I'd check it again. If there is a regulator that's crapped out, or a clogged return line, it will probably be higher. A reading from a year ago tells you that you had the right pump, or a pump properly regulated, a year ago. It doesn't tell you what's happening now.
With your indicated smell of fumes, I'd be alarmed. Like the guy with high blood pressure on the verge of a stroke, your car might be on the verge of bursting into flames. bs Sent from my iPad 4 On Jul 29, 2012, at 6:10 PM, Bruce Giller <[email protected]> wrote: > I did not check the fuel pressure on Sat.
