Fuel pressure problem
I need a little help with a fuel issue. I have a stock injected 302 (stock FPR) with a Mustang tank and pump. While working on the engine I noticed the fuel pressure at 30 pounds. It used to be 39 or 40 pounds. If I take the vacuum line off the regulator the pressure goes up to 39 pounds again. Is that the pump or the regulator that is not working correctly? I am guessing the regulator, but I thought I would get y'all to comment.
Thanks,
Steve
