Fuel pressure question

[Kejtar]

What is the fuel pressure supposed to be on the fuel rail in a 94 XJ? I was going to use the values from my 98 FSM, but the fuel setup is slightly different so now I'm not sure about the pressure similarity/difference.

I think 30-40psi...

:dunno:

but I'm not positive.

[MogifiedXJ]

39psi

I'm away from home, without FSM handy, but I thought it was supposed to be 31 regulated, 39 unregulated. I could be misremembering, though.

Thanks guys.

31 regulated, 39 unregulated.
X2 - That's what the specs are on my '88. IIRC that's the correct pressures through 1996, in '97 there was a change I think. Good Luck
