Fuel pressure.... probably a DUMB question
On my wifes JGC with a 4.0 engine, When i check my fuel pressure at the rail what should i have? Should it read a steady reading at idle? And if i have the correct pressure does that mean that my fuel regulator is good?

.... i think ~49psi +/- 5psi at the rail
.... your line and pressure is good from the back to the front
.... but, injectors/regulator/pump/filter/tank could still be the problem
.... what you got?
.... maybe some help here.... http://www.jeepforum.com/forum/f11/9...1/#post9522790
