View Full Version : Fuel pressure regulator

We have been taking short test drives with the new engine. Tonight we noticed fuel around the top of the fuel pressure regulator, it did not appear to be on the side where it enters the rail but on the top and is not squirting but "seeping". Anyone else had this and was it the regulator itself?

Sorry for the bump but did your car have hard starts when warm?

No, it didnt have hard starts when warm but after fixing it the idle's is much better and it doesnt "hunt" for an RPM when you let off the accelerator quickly now.
