I plan to add an electric fuel pump to my truck, excessive cranking to purge air after sitting is just a drag, and the thought of having to do a filter change on the side of the road sounds bloody awful!
I have a side-by-side relay mount I harvested from the local junkyard to run the pump, and the pump I have in mind is 4-7 PSI and 35 GPH.
I have read https://www.oilburners.net/threads/electric-pump.91673/ and https://www.oilburners.net/threads/e-fuel-pump-hose-splicing.92327/ for hose size and fitting rubber hose onto the stock fuel lines but still have specific questions concerning routing and filter placement.
I was planning to splice into the fuel lines after the selector valve so I can maintain the stock tank supply switching, so the rubber hose would run from the FSV to the E-pump. Should I use a course filter immediately before the pump and then have my 'primary' filter post pump? That would keep the pump cleaner and happier and still let the pump operate in a pusher configuration as it is designed since the coarse filter I intend to use is plenty 'open' enough. I have the first check valve circled in red because it might not be needed, but the second one could be needed there since if the E-pump is nnot needed while driving the mechanical pump can pump through the check valve and the filters.
Also, the consensus and advice is to block off or provide a true bypass of the mechanical lift pump, though I don't intend to do either . . . yet.
Advice on filter placement and routing is appreciated or input from others installation and how well everything runs is appreciated.
