HiSport Fuel Injection Pressure Regulator - Kit with Clip and Snap Ring Replacecment for Buick for Cadillac for Chevrolet for GMC, 3.8BAR, Replaces 19236428, 2173299

Worked good with few minor tweaking on Chevy 3500

Worked as it should. Direct fit. Easy replacement at a fraction of the cost.

I’m hesitant to write this review because of what I’ve read about this part failing after a short amount of time/milage.I’m probably about 500 miles into this new pressure regulator and it still seems to be working just fine.I have much better throttle response time as opposed to my original busted one. My truck cranks right up without any issues.Installation took less than 10 minutes. It would have been quicker if I didn’t need to fish out the old o-ring from the bad regulator.Just make sure to depressurize your fuel system before trying to replace it. I thought I had done a good job at it but it still spit a little gas at me.Other than that, this part works like a dream. I’m glad I purchased it.I haven’t had any of the noise that some reviewers state but maybe that’s because I don’t have active fuel management like some newer vehicles? I don’t know. But mine works great. I recommend it.

Fast shipping ,good price and is working well

Great fit on my 2003 Denali 6.0

Pure, utter trash. First one they sent was 80psi. Then they sent a replacement and that was at 42psi. I ended up finding a og gm regulator about 25 years old in my tool box sitting for 10 plus years. I cleaned that up with some paint thinner. Now my system runs at a happy 59psi. Spec by default should be 58-62 psi. I'm not sure why 2 different extremes on pressure between two units.

Had a hell of a time trading a random misfire code ever after replacing coil packs plugs and plug wires so I took and change ordered this got it the next day and installed problem solved

I got this from 99 Silverado it was easy to install there's been no leak everything's been good I have no problems with this
