Aeromotive 13301 Fuel Pressure Regulator for EFI and Carbureted Engines, Adjustable 2-60 PSI, Universal, Return Style, 3-Port 3/8" NPT

I was having issues with my fuel boiling off in hot conditions. This regulator has a return line which allows excess fuel to return to the tank and cool off there. Had a regulator without the return....after changing to this unit my issues went away. Holds pressure, fine adjustment to set pressure. Very well built. Would use this again.

I have a few older vehicles I work on from time to time, modifying and or upgrading them. Recently I upgraded my 1964 Buick Skylark to in-tank electric fuel pump, which was Aeromotive as well (tank and fuel pump), which was pretty darn expensive but I decided to go "cheap" on the fuel pressure regulator (had to have one with by-pass return) - so I bought a Mr. Gasket regulator for about $ 65.00. How tough could regulating the pressure be? The Mr. Gasket regulator would not hold a steady pressure (varied between 7-12 lbs), and was really noisy. This Aeromotive regulator is more than twice the price of the Mr. Gasket - but it WORKS!! When adjusting it - I could actually see the small micro-adjustments I was making on the fuel pressure gauge, and it held steady. The car actually starts easier - not sure why, but it does - almost as if it has fuel injection. AND, that is another reason to buy this 13301 Regulator from Aeromotive - it comes with another spring for higher pressures required by EFI. No need to buy yet another regulator down the road. Thank you Aeromotive!!

Had to refit my electric fuel pump from EFI to carb, so this worked great as a bypass regulator. Gave up on the FiTech EFi 600, dues to constant ECU issues with a hot big-block engine -- it does not work !Word of advice though, make sure you use NPT tapered aluminum fittings with Permatex High-temp thread sealer for the regulator fittings, otherwise be prepared for leaks... I learned the hard way.

needs one way valve for carb to hold pressure when pump is off

The lowest I can get this to go with the low pressure spring is 6psi. My Weber needs 3.5.

Real areomotive regulator. Not a repop. Works great. Using it on a blow through carb build. Boost reference works well as well.

Works great on my blown gto and looks great too.

1990 jeep wj upgraded fuel tank and electric fuel pump. This is the only regulator that was adjustable and did not flood the carb bowl. Someday when I upgrade to fuel injection it will be ready.

Installed this on my 85 land cruiser fj60 with a Weber 38 carb. I have the redline fuel pump that is 3-6 psi but has pretty consistently been putting out about 8-9psi. I've been running a pancake style regulator with no return and wanted to go bypass.From the first drive until I removed it, it leaked from the adjustment screw on the top. Took it apart and tightened everything but to no avail. I should add I plumbed it per the instructions with correct fitting size.

Works great keeps Steady fuel pressure

Did not come with the high pressure spring, so i have yet to mount or use =(

Used this for blow through turbo. Pump was that of a fuel injected car but kept it perfect @5psi until boost. Was rather surprised.

Heard good things about aeromotive products. Installed their fpr and it varies 4-5 psi at idle... not ideal or even usable...

top quality as usual. Bought it because it came with a low pressure spring for use with carbs. May go to fuel injection in the future so it is convenient that you can just change the spring out. Great addition to my collection of aeromotive items.
