ACDelco Professional 217-3299 Fuel Injection Pressure Regulator

Fits right into my 6.0l LQ4 on my 2500 sierra. Includes all hardware needed. I had trouble starting it after warm, it would take 2 key cycles for it to start and after replacing this it fires right up on the first start. No weird noises coming from the engine bay. And took about 15 minutes to install.

dispite the bad reviews, this one worked for me. I bought 2 of the other ac delco units, they both let me down.

This fuel regulator fit my 2001 5.3L Suburban perfectly. It installed easily and is solid as a rock.

Fit my applications but didnt fix my problem

Fit was fairly snug, but worked like a champ with no buzz. Solved the rough start issue on my 2002 Silverado Just make sure you remove the old small O ring before installation.

Good quality, good fit, but wrong part. This item is listed to replace oem regulator in 7.4 vortec 454. Fits, but Does not allow for correct fuel pressure. These 454’s need 60 psi this regulator is set to allow 45-50psi. Engine will run ok, but on hills or towing you’ll notice the difference. This will be the second one I’m installing with exactly the same results to find out from forums the correct part. Don’t know part number off top of my head but the pressure regulator for 4.8, 5.3, or 6.0 LS motor is the correct part.

Works as promised

Good quality no noise value was fine
