Fuel Injection Pressure Regulator Kit with Clip Snap Ring 3.8BAR

This pressure regulator was a great replacement for my 2001 GMC B7 School Bus with the 8.1L V8 gasoline engine. Very satisified with this purchase. The bus starts right up the first time & every time now, unlike before. The O-Ring was a bit hard to get seated, and had to use a Dremel to slightly saw the edges to facilitate getting it seated all the way. Other than that, everything was great!

Fixed my slow start on my 2009 Honda odyssey. Much cheaper than the entire fuel pump. Been working well for 6 months. I waited to review.

Works as it should. Replaced my old rusty n crusty FPR. Lubed up the o rings and the fitment was snug.

Despite what the pictures and description says, and what Amazon's vehicle fitment guide says, this will NOT fit a 1994 Chevy S10 Blazer. It's slightly too large (about 1 mm) and will crack the CPI spider cup if forced. The PR484 is for the newer fuel Spiders with MPI. I only wish I had measured old and new with a caliper before trying to install as they look exactly the same. For the older models, the PR147 fuel pressure regulator is what's needed.

Works fine so far.

Fit perfectly and corrected my fuel pressure issue. I'd purchased a significantly more expensive part (from Amazon) which failed within 2 weeks. This component more closely matched the OEM part I'd removed and the construction should help with the longevity of the part. Guess you don't always get what you pay for. Highly recommend this part at nearly 1/2 the price of others listed!!

Hi quality have used this brand several times without a send back

Item works like it should. Quick shipping.

Installed it, and it’s working beautifully. My fuel pressure was bleeding off rather quickly after I initially energized the fuel pump and saw a peak pressure of 65 psi. The old pressure regulator was leaking fuel and causing pressure loss directly into the intake. After installing this part, the pressure immediately built to 65 psi and then held steady at over 55 psi without bleeding off. Only time will tell how long it lasts but right now I am absolutely happy with this part.

Working fine so far, but the return outlet is angled incorrectly and pushes onto and jams up the fuel injector #2 connector once the hose is on. The return outlet is also a bigger diameter than the original and takes a bit of force to get the hose on. I ended up ordering an OE replacement, because the constant force put upon the injector connector from the incorrectly angled return outlet wouldn’t be good in the long run.

This regulator fits kymco like 200i perfect, no one sells this separately from fuel pump, or you have to order it directly from China for 65 quid. So thank you very very much. Appreciated

It’s fit and good for my gmc Sonoma 1994 3.4L cpi

Fits well on my 99 gmc 4.8 no leaks so far
