Fluctuating Fuel Pressure
Just had fuel filter changed and now fuel pressure fluctuates between 52 and 58 during normal driving. Normal pressure was 58 befor the change. This is the second filter. 1st one was Napa. 2nd was AC Delco. Any suggestions of what could be causing this?

Hi There,
It could be the fuel pump or the f/injectors leaking.However you changed the f/filter( inside tank mid year change on a 03) thats when the f/ pump should have been replaced.Since your car starts I would be looking at the injectors.
