Relatively simple question: fuel filter upstream from the pump, or downstream?
Particulars:
-Relatively low horsepower application, on road. Less than 75 hp, probably less than 50.
-Carbed engine, electric fuel pump; so this is a low-pressure pump. Maybe 5-7 psi.
- pump mounted within 2 feet of tank, pushing fuel 6 feet.
- No filter or sock in tank, straight straw feed.
This is a project vehicle, about which I will make a thread later. The problem: I acquired it non-running, probably due to electrical problems (dash was in the front seat). I've sorted the majority of that, now it's time to get it running.
Do I set up the filter so the pump pulls gas through it?
Or, should the pump pull straight from the tank and push the fuel through the filter?
I've seen it both ways on various vehicles, from the factory. I have no idea how this was originally set up, and it's odd enough that detailed info is hard to find.
Opinions ?
