Fuel Pump Bracket Double 61mm ID: The Complete Guide to Finding the Right Fit

If you need a fuel pump bracket with a double 61mm inside diameter, your best option is to buy a high-quality OEM replacement unit from a trusted brand like KEMSO. This specific bracket size is commonly found in modified vehicles, classic cars, and performance builds where dual fuel pumps are mounted inside a single fuel tank or assembly. The 61mm ID refers to the internal diameter of the bracket rings that hold the pump bodies, and getting the exact measurement is critical for a secure, leak-free installation. Below, we break down everything you need to know about this part, how to verify fitment, and why choosing the right supplier matters.

What Is a Fuel Pump Bracket with Double 61mm ID?

A fuel pump bracket is a metal or plastic frame that holds one or two fuel pumps in place inside your vehicle's fuel tank or external fuel cell. The "double 61mm ID" specification means the bracket has two circular openings, each measuring 61 millimeters in diameter from the inside edge. These openings are designed to clamp around the body of a fuel pump that has a 61mm outer diameter. This is not a common size for most stock vehicles, which typically use pumps with a smaller diameter, but it is popular in high-performance applications, such as:

  • Race cars with dual fuel pump setups for high fuel flow demands
  • Classic trucks and muscle cars that have been converted to modern EFI systems
  • Off-road vehicles that require extra fuel delivery for rough terrain
  • Diesel performance builds where dual lift pumps are needed

The bracket itself is usually made from stainless steel or powder-coated steel to resist corrosion from fuel and moisture. It includes mounting tabs or flanges that bolt to the fuel tank housing or a custom mounting plate.

Why Is the 61mm ID Measurement So Important?

Getting the inside diameter wrong by even a few millimeters can cause serious problems. Here is why precision matters:

  1. Pump Movement: If the bracket ID is too large, the pump can shift around inside the bracket. This movement can cause the pump to hit the sides of the tank, create noise, and wear out the rubber isolators quickly.

  2. Vibration and Noise: A loose fit means the pump vibrates against the bracket. This vibration transfers to the fuel tank and can be heard inside the cabin. It also puts stress on the electrical connections and fuel lines.

  3. Leak Risk: The fuel pump usually has an O-ring or rubber grommet that seats inside the bracket. If the bracket is too loose, the seal is compromised, and fuel can leak past the pump. This is a fire hazard and can cause fuel pressure loss.

  4. Installation Difficulty: A bracket that is too tight will be impossible to install without damaging the pump housing. You might crack the pump body or tear the rubber isolator, leading to premature failure.

Always measure the outer diameter of your fuel pump body with a caliper before ordering a bracket. A 61mm ID bracket is designed for pumps with a 61mm OD, but some pumps have a slightly larger or smaller diameter due to manufacturing tolerances.

Where Do You Find a Double 61mm ID Fuel Pump Bracket?

This specific bracket is not a standard part you will find at most auto parts stores. It is typically sold by:

  • Specialty fuel system retailers that cater to the racing and performance aftermarket
  • Online marketplaces like Amazon or eBay, but quality can vary widely
  • Brands like KEMSO that manufacture high-quality OEM replacement fuel pumps and accessories

When you search for a "fuel pump bracket double 61mm id," you will often find kits that include the bracket, mounting hardware, and sometimes rubber isolators. Some kits are designed for specific vehicles, while others are universal. Universal brackets usually have adjustable mounting holes or slotted tabs to fit different tank configurations.

How to Install a Double 61mm ID Fuel Pump Bracket

Installing this bracket is a straightforward job if you have basic mechanical skills. Here are the general steps:

  1. Remove the Old Bracket or Pump Assembly: If you are replacing an existing setup, disconnect the fuel lines and electrical connectors. Remove the retaining ring or bolts that hold the old bracket in place. Lift the bracket out of the tank carefully.

  2. Clean the Mounting Area: Wipe away any dirt, debris, or old sealant from the tank opening. Make sure the surface is clean and dry.

  3. Install the New Bracket: Place the new double 61mm ID bracket into the tank. Align the mounting holes with the studs or bolt holes in the tank. If your kit includes rubber isolators, place them on the bracket before inserting the pumps.

  4. Insert the Fuel Pumps: Slide each fuel pump into its respective bracket opening. The pump should fit snugly but not be forced. If it is too tight, check the O-ring or grommet. You may need to lubricate the O-ring with a small amount of fuel-safe silicone grease.

  5. Secure the Pumps: Some brackets have a set screw or clamp that holds the pump in place. Others rely on a tight fit and the pressure of the retaining ring. Follow the instructions that come with your specific bracket.

  6. Reconnect Fuel Lines and Wiring: Attach the fuel lines to the pump outlets. Connect the electrical harness. Make sure all connections are tight and secure.

  7. Test for Leaks: Before lowering the tank back into the vehicle, turn the ignition to the "on" position (do not start the engine) to prime the fuel system. Check for any fuel leaks around the bracket and pump connections. If you see a leak, tighten the fittings or replace the O-rings.

  8. Reinstall the Tank: Once the system is leak-free, reinstall the fuel tank into the vehicle. Connect the fill neck, vent lines, and any other components you removed.

Common Problems with Double 61mm ID Brackets

Even with the correct bracket, you may encounter issues. Here are the most common ones and how to fix them:

  • Fuel Pump Sits Too Low or Too High: The bracket may not position the pump at the correct height inside the tank. This can cause the pump to suck air if the fuel level is low. Solution: Use a spacer or shim under the bracket to adjust the height.

  • Bracket Does Not Fit the Tank: Some universal brackets are too wide or too narrow for a specific tank. Solution: Measure the inside diameter of your tank opening and compare it to the bracket dimensions. You may need to modify the bracket or buy a vehicle-specific kit.

  • Vibration Noise: If the pump is vibrating, the rubber isolators may be worn or missing. Solution: Replace the isolators with new ones. Make sure the bracket is bolted tightly to the tank.

  • Fuel Pressure Drop: A loose bracket can cause the pump to move and kink the fuel hose. Solution: Check the hose routing. Make sure the hose is not pinched between the bracket and the tank wall.
