Can anyone tell me if there are any differences in lb7 vs lly vs lly/lbz/lmm cp3 pumps other than the regulators?

Cp3 differences

Anyone? Reason I'm asking is I put a cp3 on my 06 lly that had the wrong regulator on it. So I put the rite regulator on it instead of changing the pump.......now that ive got it together it builds about 360 psi of fuel. Just wondering if there is a difference in the pumps or if it's just the regulators.

There is a physical difference in the lbz+ pumps but they all should interchange given the correct fpr is installed too.
Ok. That's what i was thinking. Just didn't want to have to pull the whole pump back out if it's not necessary. Guess I'll start checking injectors.
