Factory fuel pump

Thats why we sell the correct one for the early hemis and a different one for later model ones.....FYI 06 FSM says 58 +/- 2 psi not +/- 5 psi. Anyway, I was thinking we were talking early Hemi and I have to look pressure up in FSM for the specific year the cust has as they changed at least once...which is why we carry two different filter/reg units.
Funny thing, LOTS of jeep customers running Hemi with stock TJ pump and never a problem, I must not know mopar very well, only been screwing with them and building harnesses for last 18 years, only have about 30 years as a FI tech. Sorry for being so ignorant.
