electric fuel pump
I can get a 15 lb, 125 gph electric fuel pump mine is starting to leak around the pump, but i have heard that anything above 8 lbs is bad for these trucks. Could somebody define "Bad." What exactly does it do to the truck because ive heard it would change the timing; if so couldn't I just adjust the timing to fit, or does it get more complicated than that.

Pressure increases in the fuel inside the IP advance the timing.
That pump is way more than is needed.
Stock lift pump will go maybe 7 PSI max and under 40 GPH for flow.
Between the 15 PSI and 125 GPH, you may have more fuel than the return line can handle.

Is 4#'s bad at 850 rpm?
That's what I had when I checked it yesterday. Thinking the cam is worn down.
I have an AcDelco EP12S that I am really seriously thinking about installing. If for no other reason, than to eliminate the PITA pump N' bleed crap every time I work on anything fuel related. And I have a hard time leaving anything alone(mechanically) until it works perfect... (Oc anyone? lol)
Also, if I bypass the fuel pump, and run strait up to the filter.... Do I still have to remove it? I was just thinking about putting a short loop on it and letting it recirculate on itself, or just capping the ends and let it go.
Sorry for the hijack, but it's a pertinent thread, and I didn't think this deserved its own thread.
Oh yeah, I put a holly red on my Kubota. Thats where the AcDelco came from. A used one I had sitting around. No idea where it came from. Would this be better suited for this application?
