differance between LBZ and LB7 CP3

[Dallas S]

whats the difference as far as fittings and there location between an LBZ and a LB7 CP3?

reason for asking is I have a LB7 CP3 that I was going to use with ATS twin kit on an LBZ. obviously the hi pressure line has to moddified. but after looking down in the valley the LB7 pump is visually identical to the LBZ(06 truck) pump sitting down there... what gives?

truck is an 06 "LLY"

Only difference is one regulator has a 90* bend on it.
Fittings are the same

thanks! I thought they were supposed to be different, but I was wrong.

Now is there any difference in flow rate between the two? I know the LB7 is limited to 23000psi and the LBZ's can go up to about 26000psi. But how about lpm or gpm however they determined the amount per minute. I have an LB7 and wanted to make a little upgrade and was thinking either getting and LBZ regulator to increase the rail pressure but is it worth it or should I just save the $200 and put that toward a built CP3?

An LB7 CP3 can go up to 26k PSI. You just have to tune it for it.

Only thing on the LB7 pump that looks different is the regulator and there is also a port that is not located in the same spot as the LBZ. One is on the top side and the other is on the bottom side. I just had my LBZ pump off from a leak at one of the TQ plugs that came loose some how. and was going to swap in a LB7 pump but seeing if this fixed it. I have to wash under the hood but I think its fixed.
