Barry Grant 220 Fuel Pump: Powerhouse Performance for High-Demand Fuel Systems

The Barry Grant 220 Fuel Pump is a high-performance electric fuel pump designed specifically to meet the substantial fuel flow requirements of serious street machines, drag racers, oval track competitors, and high-horsepower forced induction applications. It represents a significant step up in capacity from common street performance pumps and even many "race" pumps, delivering the robust, reliable fuel supply essential for making big power reliably. If your engine demands a large volume of fuel under pressure, especially under sustained high-load conditions, the BG220 is engineered to be a cornerstone of your fuel delivery system.

Understanding the Barry Grant 220's Core Purpose

Unlike standard replacement fuel pumps or even many pumps labeled as "high-performance," the BG220 is purpose-built for engines with extreme fuel demands. Think large-displacement naturally aspirated V8s pushing well beyond 600+ horsepower, high-boost turbo or supercharged engines, nitrous oxide setups requiring massive additional fuel, or engines running aggressive alcohol-based fuels like methanol or E85, which consume roughly 30-50% more volume per horsepower than gasoline. When inadequate fuel flow becomes the bottleneck limiting your engine's potential or risking catastrophic lean conditions, the BG220 steps in as a solution designed to flow enough fuel to support over 1000+ horsepower in gasoline applications (depending on pressure and system design), and correspondingly high levels with alcohol fuels.

Key Technical Specifications Defining the BG220

The BG220's performance stems from its robust design and engineering:

  • High Flow Rate: The defining characteristic. It can deliver fuel volumes significantly higher than most competitors in its class. Official ratings often cite flow rates like 425 liters per hour (LPH) or approximately 112 US gallons per hour (GPH) free flow. Crucially, it maintains very high flow rates even at elevated system pressures (like the 43.5-58 psi commonly required by modern electronic fuel injection), which is where many lesser pumps falter. Flow varies with voltage and pressure, but even at 13.5 volts and 45 psi, it delivers well over 80+ GPH – immense capability.
  • Compact, Rugged Design: Engineered to withstand the harsh environment of racing and high-performance use. Its compact dimensions make it suitable for various mounting locations, including in-tank (with proper modifications and sumping) or as a main inline pump. Built with durability in mind to handle constant vibration, heat, and the demands of high fuel volume movement.
  • Reliable Electric Motor: Utilizes a robust, brushless DC motor technology designed for longevity and consistent output under demanding conditions. This contrasts with lower-cost pumps that might use brushed motors prone to wear, especially in high-cycle applications.
  • Dual Outlet Option: Many BG220 configurations feature dual outlet ports. This provides significant installation flexibility. Outputs can be "T"-ed together for a single large feed line, or split to supply separate lines for complex fuel systems (like feeding dual regulator setups or distinct rails). Using both outlets maximizes flow capacity.
  • Fuel Compatibility: Designed for use with pump gasoline (including ethanol blends like E10, E15), racing gasoline, methanol, and E85 (Flex Fuel). This versatility is critical for racers and performance builders who may switch fuels or require compatibility with corrosive alcohol-based fuels. Its materials and seals are selected to resist degradation from these fuels.
  • High Pressure Capability: Easily handles pressures far exceeding typical EFI requirements (58+ psi) and can be used effectively with systems requiring higher base pressures or rising rate regulators common in forced induction with mechanical fuel injection or carburetor blow-through setups. This pressure capability ensures adequate flow even as system pressure rises under boost.

When is the Barry Grant 220 Fuel Pump Necessary?

Installing a BG220 isn't typically for mild street upgrades. It's targeted at specific high-demand scenarios:

  1. High Horsepower Engines: Naturally aspirated engines reliably making 700+ horsepower or forced induction/nitrous engines exceeding 600+ horsepower (levels vary significantly with fuel type, pressure, and system efficiency, but this is a general benchmark).
  2. Fuel-Hungry Applications: Engines running methanol or high-percentage ethanol blends (like E85). These fuels require substantially higher volume flow rates for equivalent power compared to gasoline. A pump that suffices for gasoline may be dangerously inadequate for alcohol.
  3. Extended High RPM/Load Operation: Road racing, endurance racing, or high-speed street applications where the engine sustains high RPM and load for prolonged periods. Consistent, high-volume flow under these conditions is critical to prevent fuel starvation and potential engine failure. Drag racing, while intense, has shorter duration demands, but high-power levels still necessitate pumps like the BG220.
  4. Large Displacement or High Cylinder Count Engines: Big-block engines or engines with many cylinders (V10s, V12s) naturally demand more fuel volume than smaller or fewer-cylinder engines at equivalent power levels.
  5. Complex Multi-Pump Systems: Often used as the primary "lift" or "supply" pump feeding larger mechanical pumps in dedicated race setups, or as the sole powerhouse in sophisticated high-flow EFI systems.

Installation Considerations for Peak Performance and Safety

Merely bolting in a BG220 isn't enough; the entire fuel system must support its capabilities:

  • Adequate Power Supply: This pump draws significant current. It requires a dedicated high-amperage relay, heavy-gauge wiring (typically 10 AWG or larger for the feed from the battery to the relay and relay to the pump), and proper grounding. Running it through undersized wiring or a factory fuel pump circuit is a fire hazard and will starve the pump, reducing performance and lifespan.
  • Proper Filtration: Clean fuel is paramount. A quality, high-flow pre-pump filter (like a 100-micron stainless steel mesh) protects the pump from debris in the tank. A high-flow post-pump filter (10-micron or smaller, depending on injectors/carb) protects the rest of the system. Filters must be rated for the pump's flow and pressure capabilities.
  • Sufficient Fuel Line Size: The feed line(s) from the pump(s) to the engine must be appropriately sized. For a single BG220 supporting serious horsepower, -8 AN (½” ID) is often considered a minimum. Using both outlets often requires dual -6 AN lines or potentially larger single feeds (-10 AN or bigger for extreme applications). Insufficient line size is a major cause of flow restriction.
  • Robust Fuel Delivery: The pump must have an unrestricted supply of fuel. This means tank modifications are frequently needed: large sumps, multiple or enlarged pickup tubes, surge tanks (swirl pots), or dedicated fuel cells designed for high-flow pickups. A baffled tank is insufficient alone for sustained cornering or acceleration forces when moving large fuel volumes. Fuel starvation kills pumps and engines.
  • Correct Mounting: Follow Barry Grant's guidelines. Pumps should be mounted below the tank level when possible to aid priming. Vibration isolation is recommended. For in-tank mounting, ensure proper submersion and pickup positioning. For inline mounting, ensure it's positioned away from extreme heat sources and protected from road debris and impacts.
  • Reliable Regulator: A high-quality, appropriately sized fuel pressure regulator capable of handling the pump's flow and pressure range is mandatory for EFI or systems requiring precise pressure control. Bypass-style regulators must return sufficient fuel volume to the tank without excessive restriction.

    **Robustness and Durability:** Built specifically for the harsh conditions and sustained high demand of racing, not adapted from a street application. Materials and motor technology enhance longevity.
  • Reliability Under Pressure: Maintains high flow rates consistently at the elevated pressures required by modern EFI and boosted applications, where lesser pumps see dramatic flow falloff.
  • Alcohol Fuel Compatibility: Engineered from the ground up to handle the corrosive nature and higher volume requirements of methanol and E85.
  • Dual Outlet Flexibility: Provides superior installation options for complex fuel systems or maximizing flow with large single feeds.

System Sizing and Potential Need for Multiple Pumps

While the BG220 is potent, some applications demand even more flow:

  • Extreme Horsepower (1200+ HP on Gas, 900+ HP on E85/Methanol): Depending on pressure and system efficiency, a single BG220 might approach its limits. Multiple BG220 pumps (or stepping up to larger pumps like the BG400) become necessary.
  • Very High Boost Pressure or Large Displacement Forced Induction: Systems requiring very high base pressure (e.g., 60-70+ psi) for mechanical fuel injection combined with high boost levels place enormous demands on flow capability. Multiple pumps are common.
  • Redundancy (Safety Critical Applications): Some race series or high-value engines employ dual BG220 pumps for redundancy. If one fails, the other can often supply enough fuel to get the vehicle off the track safely without causing a lean meltdown.
  • Complex Fuel Systems: Engines with staged or independent fuel systems (e.g., primary and secondary injectors, dual nitrous plates) might utilize multiple BG220s for dedicated circuits.

Barry Grant 220: Compatibility Notes

  • EFI Systems: Primarily designed for high-pressure EFI systems or complex multi-pump layouts (like feeding a mechanical pump). Requires appropriate EFI regulator and large lines/injectors.
  • Carbureted Applications: Can be used with carburetors but requires a high-quality bypass regulator to reduce pressure to the low (4-8 psi typically) level carburetors require. Its high flow volume is often overkill for most carbureted engines unless extremely powerful, heavily nitrous-injected, or running alcohol. Simpler pumps suffice for many carbs. Exceptions are carbureted engines with extreme forced induction (blow-through) setups requiring high fuel pressure under boost.
  • Standalone vs. In-Tank: Can be mounted in-tank (needs proper pickup/sump setup) or inline. Inline mounting requires careful consideration of suction head to prevent vapor lock or cavitation.

Maintenance and Care for Longevity

To ensure the BG220 serves reliably:

  • Fuel Quality: Always use clean, uncontaminated fuel appropriate for the pump and engine. Stale fuel or debris accelerates wear.
  • Filter Changes: Replace pre- and post-pump filters religiously according to the manufacturer's schedule and your inspection. More frequent changes are needed in dusty environments or after engine work.
  • Electrical Connection Integrity: Periodically check connections at the pump, relay, and battery. Loose or corroded connections cause voltage drop, reducing pump performance and potentially damaging the motor. Protect wiring from chafing.
  • Monitor Performance: Pay attention to fuel pressure readings under varying load conditions. A noticeable drop in pressure, especially under peak load, can indicate pump wear, clogged filters, or other system issues. Unusual pump noise can also signal problems.
  • Storage: If storing a vehicle, follow recommended procedures like using a fuel stabilizer and potentially running the pump with stabilized fuel in the lines before storage. For very long storage, consult Barry Grant guidelines.

Verdict: The Go-To Pump for Serious Power Demands

The Barry Grant 220 Fuel Pump stands as a cornerstone component for high-horsepower, fuel-intensive automotive applications where lesser pumps simply cannot deliver. Its robust construction, exceptional flow capacity under pressure, and compatibility with aggressive fuels like methanol and E85 make it a trusted choice among professional engine builders and serious enthusiasts. It addresses the critical need for reliable, high-volume fuel delivery that prevents lean conditions and unlocks the full potential of powerful engines.

However, realizing its full benefits requires commitment. Installation must include a supporting ecosystem: adequate electrical power with dedicated wiring and relay, large enough fuel lines, superior filtration, and a tank setup guaranteeing a constant, air-free fuel supply (often requiring sumps or surge tanks). While not a universal solution for every performance car, the BG220 is the essential choice when your engine's fuel demands push beyond the capabilities of common high-performance pumps. For forced induction beasts, all-out race engines, big-blocks on nitrous, or vehicles dedicated to high-percentage ethanol or methanol, the BG220 delivers the foundation necessary for both peak power and engine safety. Its reputation for reliability under extreme conditions reinforces its position as a critical component for those building and maintaining serious horsepower.
