I've search everywhere I can think, but I cannot find the maximum and/or nominal flow rate of the 2004 lift pump. Does anyone have this information or know where it can be found?

Thanks!

I could not find any spec either. The manuals say it always provides adequate flow. That is a crock.

They do not want you to know what it is supposed to supply re flow or pressure anymore.
I guess with the CP3 being a 2 stage pump they think the transfer pump is just a helper.

In the 2003 Service manual all it says is Min of 9.5 PSI. I assume that is at idles, it doesn't say.

Mine pushes 6-8 at idle and cruising. At full throttle it drops to 0!! Under moderately hard acceleration it drops to around 2.5psi.
