🔧 Enhanced Delphi FP10075 Fuel Injection Pressure Regulator – Optimize Your Engine's Performance! Review

Works well. All O-rings supplied with this part will fit the 2001 S10 4.3 engine. No problems after 6 months of use. Highly recommended.

Yes this regulator was fitted and unfortunately it held less pressure than the one that was removed from the car. In fact, it doesn't hold pressure after the pump shuts off. Okay that's not true, it's reduced down to 10psi.

very good injector pressure regulator does a good job Seems well made I try to use genuine parts on my GM vehicles so it fits the bill I always adhere to keep trying factory parts, whether domestic or foreign, if i can get them at a reasonable price, the aftermarket is as good as factory parts, but i seem to have fewer problems with original factory parts, foreign or domestic cars.

Works as intended, like many replacement parts, looks different but suits the application. I noticed feedback when the fuel pressure was released after installation. If new O-rings are not properly lubricated with engine oil before installation, they may become damaged or dislodged during installation. housing as this can result in the new part not fitting properly and fuel leakage.
