Thanks for the input guys. I like the idea of air separation and I think the Cummins/Carter pump is a little overkill for the application. I might go back to an inline. 4-7psi seemed to work just fine and even when the cheap p.o.s. died it it didn't cause a restriction due to its flow-thru design. The dumb thing is it didn't die... Had the wires pulled too tight and they broke where they enter the pump.
How much does a Cummins/Carter setup run??
LOL... you know, that 'cheap pos' flow through 'clicker' type pump made by Facet.. is probably the highest quality pump out there! This company was built up in WWII for exclusively building fuel pumps for the fledgling aircraft industry.
It's main benefit is when the wires do get pulled out of its body... it'll still flow. All there is inside is a lateral moving hollow armature, with one way flap valve at each end.
The caveat to this pump is... crud. it'll stop that clicker in its tracks. But in reality, what pump isn't prone to dirt? Sometimes whacking it will jar it loose. And putting a screen on the suction side of any diesel system (other than under the hood) is problematic as well. (wintertime anyways) That is why our oem filters have the heating element.
Btw, FMI, does the stock lib fuel draw module have a sock type filter in the tank? If it does, that probably would be enough to protect the clicker pump.
The few old tractors I run with the Facets have a small 120 micron metal canister screen just ahead of those pumps, which eliminated the contamination problems
