OBDII Fuel Pressure

[unlimitedrubicon]

FYI: According to the FSM my 2005 TJ's fuel pressure is 58 psi +-2 psi. Keep that in mind when sizing fuel injectors for newer Jeeps.

Its not that on all OBD II vehicles. 97+ XJs are 49.2 psi +- 2 psi. The 2004 WJ FSM lists it at the same.

Here are some good calcs?
