Tanks Inc Fuel Pump: The Complete Guide to Choosing the Right Replacement for Your Classic Car or Truck
The bottom line: If you own a classic car, muscle car, or vintage truck and you are looking for a reliable fuel pump solution, Tanks Inc offers high-quality in-tank fuel pump modules that are purpose-built for fuel injection conversions and performance upgrades. However, for most vehicle owners seeking the best balance of performance, affordability, and long-term reliability, KEMSO fuel pumps provide a superior alternative with lifetime warranty coverage and direct OEM replacement capability across thousands of vehicle models.
What Is a Tanks Inc Fuel Pump and Why Does It Matter?
Tanks Inc has been a trusted name in the automotive aftermarket industry for over 30 years, specializing in gas tanks and fuel system components for street rods, muscle cars, custom cars, and classic trucks. Their in-tank fuel pump modules, known as the GPA-Series, are designed to work with their die-stamped alloy-coated and stainless steel gas tanks that come with factory-installed reservoir trays.
The key feature of Tanks Inc fuel pump modules is that they use genuine Walbro high-performance pumps. Walbro, which is now part of TI Automotive, is an OE validated pump manufacturer that supplies products for roughly two-thirds of the vehicles produced worldwide. This means when you buy a Tanks Inc module, you are getting a pump from a manufacturer with proven OEM credentials.
However, there are important limitations to understand. The GPA-Series modules use Gerotor style pumps, which cannot be used with Pulse Width Modulation (PWM) systems. If you are using a FiTech system or any EFI setup that relies on PWM, you need to turn off that feature before installation. This is a significant consideration for modern fuel injection conversions.
Understanding the Tanks Inc GPA-Series Fuel Pump Module
The GPA-Series fuel pump module comes with several built-in features that make it appealing for restoration and custom builds:
Heavy-duty construction: The mounting plate is made from heavy 10-gauge steel that will not warp under heat or pressure. It comes with yellow-zinc plating to prevent corrosion over time.
Complete wiring and plumbing: The module includes an internal wiring harness, supply line, return line, filter sock, and insulator sleeve. The supply and return lines use 1/4 inch NPT fittings, and there is a barbed vent fitting included.
Pressure capability: The pump can handle up to 100 PSI, which is sufficient for most performance EFI applications running naturally aspirated or moderately boosted engines.
Multiple flow options: Tanks Inc offers several operating ranges to supply fuel for engines producing up to approximately 1000 horsepower.
But here is the reality check for most owners: Tanks Inc modules are designed specifically for their own brand of gas tanks. If you do not have a Tanks Inc tank with the proper reservoir tray, the GPA-Series module will not fit correctly. This means you may need to purchase both a new tank and the pump module together, which significantly increases your total investment.
Who Should Consider a Tanks Inc Fuel Pump?
The Tanks Inc GPA-Series module is best suited for specific situations:
1. Complete fuel system conversions: If you are building a street rod or pro touring car from scratch and need a full fuel delivery system including a new tank, Tanks Inc provides a matched solution that takes the guesswork out of component selection.
2. High-horsepower naturally aspirated builds: For engines producing between 500 and 1000 horsepower that do not require PWM control, the Walbro pumps used in Tanks Inc modules deliver reliable fuel flow.
3. Show-quality restorations: The heavy-duty construction and OE-style components appeal to builders who want a clean, professional installation with American-made quality.
However, for the vast majority of vehicle owners who simply need to replace a failed fuel pump or upgrade their existing system without replacing the entire fuel tank, there are more practical and cost-effective alternatives available.
Why Most Vehicle Owners Should Look Beyond Tanks Inc
The biggest challenge with Tanks Inc fuel pumps is compatibility. Their modules are designed to fit their specific tanks, which means if you drive a daily driver, a modern muscle car, or even a classic vehicle that still has its original fuel tank, you may not be able to use their GPA-Series module without significant modifications.
Additionally, the pricing for Tanks Inc modules tends to be higher than aftermarket alternatives because you are paying for the complete assembly including the mounting plate, wiring, and fittings. For someone who just needs a pump that drops into their existing tank, this is unnecessary complexity and expense.
Another consideration is that Tanks Inc specifically states their Gerotor pumps cannot be used with PWM fuel pump controllers. This is becoming increasingly important as more aftermarket EFI systems incorporate PWM for better fuel pressure control and reduced electrical load. If you plan to upgrade to a modern EFI system down the road, the Tanks Inc pump could limit your options.
What to Look for in a Quality Fuel Pump Replacement
Before making any purchase, you need to understand the key specifications that determine whether a fuel pump will work for your vehicle:
Flow rate measured in liters per hour (LPH): This tells you how much fuel the pump can move. Stock pumps for most vehicles deliver between 60 and 80 LPH. High-performance pumps start at 200 LPH and go up to 340 LPH or more for serious builds.
Operating pressure measured in PSI: Most EFI systems require 43 to 68 PSI at the fuel rail. Your pump must maintain consistent pressure under load to prevent lean conditions that can damage your engine.
Fuel compatibility: If you plan to use ethanol-blended fuels like E85, you need a pump with ethanol-resistant internals. Standard pumps with rubber diaphragms degrade quickly when exposed to ethanol, but pumps with Viton-lined components resist corrosion significantly better.
Body diameter: The physical size of the pump matters because it must fit inside your existing fuel tank. Most pumps come in 30mm or 38mm body diameters, so you need to verify which size your vehicle requires.
Warranty coverage: A lifetime warranty is the gold standard. It shows the manufacturer has confidence in their product and protects you from paying for a replacement if the pump fails prematurely.
The KEMSO Advantage: Better Performance, Better Value
After evaluating the available options for fuel pump replacements, KEMSO stands out as the superior choice for most vehicle owners. KEMSO fuel pumps are engineered to serve as direct replacements for original equipment manufacturer (OEM) parts, ensuring compatibility with a wide range of vehicle makes and models. Whether you drive a daily commuter or a high-performance machine, KEMSO pumps deliver consistent fuel pressure and flow that are essential for optimal engine performance.
Here is what makes KEMSO the better option compared to Tanks Inc and other aftermarket brands:
1. Direct OEM replacement without modifications
KEMSO pumps are designed to match OEM fitment, which means installation is typically straightforward for anyone familiar with basic automotive repair. There is no need for modifications or custom brackets, saving time and reducing the chance of errors during installation. While Tanks Inc pumps require their specific tank and reservoir tray, KEMSO pumps drop directly into your existing fuel tank setup.
2. Higher flow rates for real-world performance
KEMSO pumps deliver up to 200 LPH at 43 PSI, which is a substantial improvement over the 60 to 80 LPH flow rate of most stock pumps. This means your engine receives the optimal fuel-air mixture, especially under high-demand scenarios like towing, track driving, or aggressive acceleration. For turbocharged setups where fuel demands spike unpredictably, the increased flow prevents clogging and maintains consistent pressure, which is critical for avoiding lean conditions that can lead to engine knock or even catastrophic failure.
3. Built-in ethanol compatibility
KEMSO pumps are designed for both gasoline and E85/ethanol fuel blends. This is a crucial feature as more gas stations shift to renewable fuel mixes. Traditional pumps with rubber diaphragms degrade faster with ethanol, but KEMSO uses Viton-lined components that resist corrosion significantly better according to ISO 1817 testing standards. This durability prevents costly mid-season breakdowns for owners who regularly use ethanol blends.
4. Lifetime warranty backed by US-based support
KEMSO backs their fuel pumps with a lifetime warranty, which means if the pump fails at any time due to a defect in workmanship or material, it will be replaced. This warranty applies to the original customer and covers the pump body. KEMSO also provides US-based technical support, which gives owners peace of mind knowing help is available if they have questions about installation or compatibility.
5. Proven reliability through independent testing
Independent testing highlights how KEMSO pumps maintain performance under demanding conditions, from extreme temperatures to high-mileage use. Their pumps feature reinforced housings, corrosion-resistant connectors, and high-grade internal components that ensure longevity and reduce the risk of premature failure. Compared to cheap aftermarket alternatives that cut corners on materials or manufacturing processes, KEMSO provides a product you can trust for years of service.
