217-3073 (19245530) Fuel Injection Pressure Regulator Kit with Clip and Snap Ring

I want to start the vehicle and it takes longer to crank than it normally used to but it still would start. The vehicle ran fine but I noticed certain times the cel light would flash while driving I look for vacuum leaks and everything else but I couldn't figure out what was going on. I pulled the vacuum hose off this and notice there was fuel in it so therefore the diaphragm must have failed and had been sucking fuel in through the fuel rail through the diaphragm. Vehicle always had a bit of a goofy idol but never any thing to cause alarm after putting plugs and wires on it still had that odd idle but vehicle ran fine. Once I changed this whole new vehicle. Did idle super smooth it instantly starts up no more flashing cel which means I was running very rich which can ruin your catalytic converters. I also ordered the vacuum line going to it. Do not order the cheap $7 lines. Order the gm1 or the dorman one which is about 20 bucks. They are extremely well made and formed correctly. Plus this is a GM part little better quality even though it's probably made in China anyway. It works great

Did exactly what it needed to do. If you have hot start issues, pull off that line that goes to this and see if Gasoline comes out. If it does, you need to replace the fuel pressure regulator with this. IT worked great and fixed my issue.

Seemed to work like it should

This thing makes a ton of noise, unplug it and the noise goes away. High fuel trims (15-20%) as well. Trims go down below 10% when it’s unplugged.

Works so far. Can't speak on longevity yet. Fit my 2002 GMC Yukon XL 2500 6.0L.

Pay close attention when removing clip as to not have a bad under pressure leak after replacing.

18 months ago I replaced a regulator with a Auto Box store generic. It went bad in about 12 months. I just put this on the truck this evening. I'm hoping I get a better life out of this one. I'll bump it to 5 stars if it holds up. Tips: - De-pressurize your fuel line - Remove Fuel Pump relay under your hood and run the engine until it dies to remove pressure from the line. - Make sure all the gaskets and pieces from your old regulator are out of the fuel rail. A jewelry screwdriver or scribe goes a long way. I didn't have the typical warm start problems. My problem is fuel line rattle. I hear it on take off from a stop. Not much more to say. It's an easy job. If you're looking a year from now ask me how this one is holding up.

A lot cheaper than the parts store, and it fits just the same.

ركبته وبعد كم شهر سار يهرب بنزين شريته قبل ٧ شهور

mi 5.3 estaba con mezcla rica y olía mucho a gasolina resulto ser que el regulador estaba malo y lineaba gasolina a la admisión y. posteriormente caía a los cilindros haciendo que cuando quemara esa gas el humo saliera y oliera a gasolina mucho, reemplacé la parte y se solucionó, lo recomiendo

Excellent product no issues. Took care on my off idle hesitation problems.
