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?

Anybody, anybody?

You might contact http://kennedydiesel.com/ He knows all about these lift pumps.

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.

Thanks for the info. I must be dense but what does IIRC stand for. I see it every where and have never been able to figure it out.

If I Remember Correctly

CS-Dmax,


Thanks!!! Boy do I feel stupid now.http://www.dieselplace.com/forum/smileys/Confused.gif

Dave, the FM100 series is rated at 80Gal/hour (1.33gal/min) and 350HP. The FM1000 series is 180gal/hour (3 gal/min) and 600HP.


No idea on the delco pumps.
