Arctic Cat 700 EFI Fuel Pump Replacement: Complete Guide for a Smooth Fix

If your Arctic Cat 700 EFI is experiencing hard starting, sputtering at high speeds, or complete engine failure to start, the fuel pump is likely the culprit and needs replacement. The bottom line is this: replacing the fuel pump on your Arctic Cat 700 EFI is a straightforward job that most DIY enthusiasts can handle in an afternoon, and choosing the right replacement part is critical to getting your machine back on the trails without breaking the bank. This guide covers everything you need to know about the replacement process, compatible parts, and where to buy a reliable fuel pump that will last for years to come.

Signs Your Arctic Cat 700 EFI Fuel Pump Is Failing

Recognizing the early warning signs of a failing fuel pump can save you from being stranded miles away from home. The most common symptoms include:

  1. Engine cranks but won't start – This is the most obvious sign. When you turn the key, you hear the starter motor spinning, but the engine never fires up. If you don't hear a faint whirring sound from the fuel tank when you turn the ignition to the "on" position, the pump is likely dead.

  2. Sputtering or hesitation at high speeds – A weak pump cannot deliver enough fuel pressure under heavy throttle, causing the engine to hesitate or surge.

  3. Loss of power when climbing hills – Your Arctic Cat 700 EFI may struggle to maintain speed on steep inclines because the pump cannot keep up with fuel demand.

  4. Whining noise from the fuel tank – A loud, high-pitched whine coming from the tank area indicates the pump is running dry or the internal bearings are wearing out.

  5. Poor fuel economy – If you notice you are filling up more frequently than usual, a failing pump may be causing the engine to run rich or lean.

According to user reviews from Fuel Pump Factory, customers have reported that pumps quit working within two years of installation, emphasizing the importance of choosing a quality replacement part. One customer from Tallassee, Alabama, noted, "Just put the third pump on in 2 years. They seem to quit working pretty quickly. Starting to get expensive."

Step-by-Step Replacement Process

Replacing the fuel pump on your Arctic Cat 700 EFI is manageable with basic tools. Follow these steps carefully.

Tools and Materials Needed

  • New fuel pump assembly (preferably with regulator included)
  • Screwdrivers (flathead and Phillips)
  • Socket set with extensions
  • Fuel line disconnect tool (if needed)
  • Clean rags or shop towels
  • Safety glasses and gloves
  • Fire extinguisher (keep nearby as a precaution)

Safety Precautions

  1. Work in a well-ventilated area – Gasoline fumes are highly flammable.
  2. Disconnect the battery – Remove the negative terminal to prevent any electrical sparks.
  3. Release fuel pressure – Locate the fuel pump fuse and remove it, then crank the engine for a few seconds to relieve pressure.
  4. No open flames or smoking – Keep all ignition sources away from the work area.

Removal Instructions

  1. Remove the seat and side panels – Access to the fuel tank is achieved by removing the seat and body panels on most Arctic Cat models.

  2. Disconnect the fuel lines – Use a fuel line disconnect tool to separate the fuel supply and return lines from the pump assembly. Be prepared for some fuel spillage.

  3. Remove the electrical connector – Unplug the wiring harness from the pump assembly.

  4. Remove the retaining ring or screws – The pump assembly is held in place by a large retaining ring or several screws. Use an appropriate tool to remove them.

  5. Lift out the pump assembly – Gently lift the pump out of the tank. It may be attached to a bracket or float arm, so tilt it slightly to avoid damaging the fuel level sender.

  6. Disassemble the old pump – Remove the pump from the bracket or housing. Note the orientation of all components, including the fuel strainer, O-rings, and grommets.

Installation Instructions

  1. Install the new pump – Place the new pump into the bracket, ensuring correct orientation. Some pumps come as a complete assembly with the regulator attached, which simplifies the process.

  2. Replace O-rings and grommets – Install the new O-rings and grommets that come with your replacement kit. This is critical for a proper seal and preventing fuel leaks.

  3. Lower the assembly into the tank – Carefully guide the pump assembly back into the fuel tank. Make sure the fuel level sender arm does not bind.

  4. Secure the retaining ring – Tighten the retaining ring or screws to the manufacturer's specifications. Do not overtighten.

  5. Reconnect fuel lines and electrical connector – Push the fuel lines onto the pump ports until they click into place. Reattach the wiring harness.

  6. Reinstall seat and panels – Replace all body panels and the seat.

  7. Prime the fuel system – Turn the ignition key to the "on" position for a few seconds to allow the pump to pressurize the system. Repeat this a few times before attempting to start the engine.

  8. Check for leaks – Start the engine and inspect all fuel connections for any signs of leakage.

Why Choosing the Right Fuel Pump Matters

Not all aftermarket fuel pumps are created equal. Some customers have reported issues with fitment and durability. One reviewer from Grand Forks, North Dakota, noted that a pump was "1/2 inch too long so it didn't fit in the fuel tank," though they were able to resolve the issue by using the regulator that came with the kit. Another customer from Omaha, Nebraska, said the pump "worked great" but required "a small modification for the fuel pump grommet," after which it "worked amazing."

The key features to look for in a quality replacement fuel pump include:

  • Drop-in design – The pump should fit without requiring modifications to wiring or mounting hardware.
  • Upgraded internal components – Look for pumps with improved bushings, turbine impellers, and Japanese armature electric motors, which provide better performance and durability.
  • Advanced pressure relief valve – This ensures the correct PSI is maintained, preventing damage to the fuel system.
  • Corrosion-resistant case – A polished case helps minimize seizing during periods of non-operation, which is common for ATVs and UTVs that are stored for the winter.
  • Compatibility with ethanol-blended fuels – Many modern gasoline blends contain up to 10% ethanol, which can damage older pumps. Choose a pump specifically designed for ethanol compatibility.

Where to Buy an Arctic Cat 700 EFI Fuel Pump

You have several options for purchasing a replacement fuel pump, ranging from OEM dealers to online retailers.

Tips for a Successful Fuel Pump Replacement

  1. Replace the fuel strainer – Always install a new gradient density fuel strainer with the pump to ensure superior contaminant filtration.

  2. Use the correct O-rings – The O-rings and grommets included in the pump kit are specifically designed for your application. Do not reuse old seals.

  3. Check the fuel lines – While the tank is open, inspect the fuel hoses for cracks or deterioration. Replace them if necessary.

Frequently Asked Questions

How do I know if my Arctic Cat 700 EFI fuel pump is bad?

The most common signs include: the engine cranks but won't start, you hear a whining noise from the fuel tank, the engine sputters at high speeds, or you experience loss of power when climbing hills. If you turn the ignition to the "on" position and don't hear the fuel pump prime for 2-3 seconds, the pump is likely faulty.

Can I replace just the fuel pump motor instead of the entire assembly?

Yes, some aftermarket suppliers sell just the pump motor without the bracket, regulator, or strainer. However, most mechanics recommend replacing the entire assembly, including the regulator and strainer, to ensure long-term reliability. The OEM assembly includes multiple components that work together, and replacing only the motor may leave worn O-rings or a failing regulator in place.

How much does a replacement fuel pump cost for an Arctic Cat 700 EFI?

Prices range from approximately $99.99 for aftermarket pumps on Amazon to over $700 for OEM assemblies from Arctic Cat parts houses. Aftermarket pumps with a regulator included typically cost between $99 and $200, depending on the brand and features.

How long does it take to replace the fuel pump?

A DIY replacement typically takes 1 to 3 hours, depending on your mechanical experience and the specific model. The most time-consuming part is removing and reinstalling the seat and body panels to access the fuel tank.

Do I need to replace the fuel pump regulator at the same time?

Many aftermarket fuel pump kits include the regulator, and it is generally recommended to replace both at the same time. The regulator is responsible for maintaining correct fuel pressure, and a failing regulator can cause symptoms similar to a bad pump. Some pumps are sold with the regulator included as a single unit, such as the FPF Fuel Pump W/Regulator for 2008-2010 Arctic Cat models.

What is the fuel pressure specification for Arctic Cat 700 EFI?

The standard specification is 3.0 bar (approximately 43.5 PSI) at 13.5 volts. Most quality replacement pumps are designed to meet this specification. The FP-283-PR-010 pump from Fuel Pump Factory, for example, delivers 100-120 liters per hour at 3.0 bar and 13.5 volts.
