OK great thanks so much!
What about the fuel filter manager psi?
We did a little bit more searching and found that the fuel pump / lift pump attached at the bottom-front of the engine outputs about 8-9 psi, so the thought crossed our mind to just use this lift pump instead of getting an additional one. However, to do this we will probably need to get an additional 3 port valve in addition to the 6 port valve we already have in order bypass our Chevy G30's original fuel filter which is located directly above the engine right behind the injector pump (IP).
We ran into a hiccup though when we found that our G30's fuel filter is part of a "fuel manager":
http://www.thedieselstore.com/template/ ... dIXBxUju1E this "Fuel Manager Complete 'Top Load' Assembly" is a fuel filter & water sensor/seperator and has the following OPTIONAL features which I'm not sure whether or not our Chevy G30 utilizes:
In-unit heater. (heater only heats fuel to 45º F (then shuts off) & NOT designed for use with SVO or WVO alternative fuels)
Electronic "water-in-fuel" indicator.
Hand primer.
Electric lift pump
Filter change indicator
The psi of the lower lift pump is around 8 or 9 psi, but we don't know about the psi coming out of the fuel filter/manager up top.
Do you think the fuel manager is utilizing it's built in lift pump?
Does anyone know the psi needed before sending fuel to the injector pump?
Thanks so much!
