Adjustable Carb Fuel Pressure Regulator Kit Universal Manual 1-5 Psi Fuel Pump Pressure Regulator FPR for Carburetor Engine with 8mm 10mm adapters

Worked as described. I’ve used this device twice and both worked to solve my problem with fuel pressure being to high causing flooding issues with the engine.

Like all parts inspect. I don’t recommend using provided hose it is not fuel line grade.The reducer its self works fine. First flip it over inspect the screws are present and tight, inspect for debris.Wrap the brass fitting of your choice with teflon tape in the opposite direction as threading direction.Insert and tighten to approximate 10ft lbs.Slide on hose clamps, I do not recommend the provided ones but they seem to be ok.Power on the fuel pump prime the line and inspect for desired flow rate. I would install a fuel pressure gauge after the regulator.

It works great once you install it in the correct direction one is in and 4 which maybe looks like an arrow is out.My machinist said the did a good job making it. Left us Teflon tape to help seal it up and it had extra ports to fit. We did not have to clean it or find burrs.

Great deliverirs, product seems to be first class.

This did not regulate my fuel pressure I still have 9 psi of pressure with it turned all the way down and it leaks fuel out of the nob do not buy it it is total garbage

Worked good

The fuel pressure regulator does not regulate the pressure of the fuel as described. My carburetor gets overfilled even on the lowest setting. It does not seem to affect much the pressure. Maybe I have a defective one but I can not know for sure. One thing I knew before buying is that I also read some comments saying that this product does not work but I ignored them when should not have.

It does list 7 PSI as recommended max input pressure. My setup had input of 8 PSI and this regulator didn't work at all. My bad but you'd think there would be a little leeway....
