Fuel Regulator

[Shondue]

I came home from work last night and the explorer wouldn't start, so when I opened the hood and turned on the key I could see fuel shooting about 18" out of the intake area towards the passenger fender. The local autozone folks seemed to all think that it was the pressure regulator. Has anyone had this problem with the regulator before? How much presure is on the regulator from the pump? Is there any trick to getting the regulator out of the fuel rail? Also in an unrelated problem when the motor warms up the check engine light will come on for brief periods of time and then go back off. It is never on when the motor is cold and never has stayed on long enough to go get the code read. Any ideas and what it could be and how to fix it?

Hard to imagine

a pressure regulator leaking like that. Sounds more like a fuel injector hose connection. FPR is in that side and only mounts with 2 bolts, screw off the return line, and slide off the vacuum line. Shouldn't take more than 10 minutes and about $60. I'd verify where the gas is coming from first and use some safety glasses! Maximum pressure is 39#.

Could be a pinhole in the line. I'd check it ASAP before :fire:

Lucky you that the engine don't start! Otherwise is for sure that you get a fire under the hood and good bye X
