Your cart is empty.When converting your fuel system to a return style EFI setup, the biggest challenge can be plumbing the fuel lines. Holley continues to be the leader in fuel system development to make your life easier! The new Holley EFI Filter Regulator assembly simplifies your installation by combining the fuel filter and regulator in one assembly that can be mounted in the rear of the vehicle. Thus making your return line much shorter. The aluminum assembly contains a 175 GPH 10 Micron filter and a regulator preset at 59. 5 psi. The filter regulator comes in 3/8" NPT or 8 AN port sizes to match most EFI fuel systems.

It is a Play-N-Play item. You will need to make sure the old filter comes out with the old one land that the new regulator is installed complete in and without crushing the outer frame. That will change the pressure within the system and can cause it not to perform correctly. Highly recommend getting a fuel gauge to monitor the system’s pressures.

Pressure is still 5 to 6 lb higher than it's supposed to be for highly sniper. Very disappointed I'm going with an inline adjustable like in the photo going to work way better don't have to deal with bad productions

Had one of these regulators fail after spilling water on my engine and EFI unit while hot. Bought a second one, but it promptly failed due to a dent (blocking flow) in my return line from towing the vehicle while the first regulator was broken. Had to get a second replacement to get my vehicle running again.Definitely carry one of these in your vehicle as a spare if you're going on any long trips.That said, I doubt I'll be regretting converting to EFI when winter rolls around and my vehicle starts right away.
