Fuel Pressure Regulator Kit Carburetor Carb Fuel Pump FPR, Adjustable Gunmetal Fuel Pressure Regulator Universal for Carburetor Engine

The original bladder pump failed so I put in an electric pump which I also got on amazon. The pump is listed to put out 2-3 PSI. The pump was relatively close in output pressure for the carb but would the carb would eventually overflow/flood. So I thought I would try this regulator. Upon the first try I turned it to the lowest setting. No flooding, but the ATV would not idle correctly. So I clicked it up one tick. I repeatedly "tuned" it in until the ATV would idle as required. I suspect everyone's system is unique so tuning will vary. My 2006 Sports Yamaha Rhino 660 has never run better. Great to start it by just turning the key. I got every thing to easily fit behind the passenger seat. Using a multi meter, I found and used a power line that energized when the key was turned on. I left the existing pump in place, but used the existing 5/16 gas lines, only needing to get a couple of feet and some clamps.

Works great, super easy installation

Seems to be working right but I haven't pressure tested it. I replaced the junk hose clamps, and added Teflon tape to the fittings. No leaks that I can find.

Does not regulate properly at 1 psi

Just what I needed, was having issue with excessive fuel pressure causing flooding of carburetors, able to reduce pressure to eliminate flooding.

Can say much for the regulator, it seemed to help, but i only used it a week until my low pressure pump arrived. Upon removal, I had large pieces of rubber hose in my inline filter. Hoses disintegrated in a weeks time. Inside wall seperation. Get good fuel hose and hose clamps for installation.

I don’t have a guage so I can’t say forsure but it didn’t stop the car from running hopefully it’s accurately operating

Do not buy, used all adjustments and made no difference in pressure. But not all covered in gas so I can not return. Stay away from this product.
