Does anybody know the difference in flow rates of the Stanadyne FM-100 compared to the 6.5 lift pumps? I know the FM-100 is rated to something like 350 HP how about the AC Delco lift pump?
Dave, I know both are running in the field. I have the 6.5 version and sdaver has the FM100 IIRC. Both seem to do fine for out application. I can turn mine up to around 6-7 psi with the bypass closed. I want to say the FM100 is about the same, again IIRC.
