YUNDA PR217 PR203 Fuel injection pressure regulator for Buick Pontiac Chevrolet GMC Isuzu Cadillac PR203

Super price point for this China made (most are) regulator. If you have a GM vehicle that has a buzzing regulator this replacement does the trick. Out of the box on my 00' Silverado w/ 5.3L I had to remove the plastic spacer that comes between the fuel rail and regulator body. The clip provided would not allow regulator to be retained with the spacer and does not aid in sealing. I used the old O ring in addition to the new one on the body that seals the unit in the fuel rail. Leak free and adjusted to 54 psi. no buzzing. Yea

Was able to get this to work on my 2003 gmc 1500hd but it is not a direct replacement. I had to use the spacer from the factory regulator as the one that came with this one was too thick to allow installation of the retaining clip.

Looks like it's dose the trick

I had to take the black bushing off the old one and install on new one. It worked great though.

Excelente

The clip would fit over the item and the mount. The lip is too wide. Threw away and bought an OEM regulator. Get what you pay for.

Had to Jerry rig this part,did not fit as said . I couldn't wait to remove this part and install AC Delco it fit perfectly

Good.
