Fuel system part missing ???

[koldcustoms]

I've got an '87 Ranger with the 2.9L, and the duel fuel tank option installed. The set-up is as follows: pump/pump (1 inside each tank) -> selector valve -> filter bowl -> in-line high pressure pump -> in-line filter -> fuel rail.

I've troubleshot a intermittent fuel problem to the high pressure pump. While checking all the system components, I discovered there wasn't a filter element inside the bowl, between the selector valve and the H/P pump. According to the manual, there were 2 different filter assemblies used in the Rangers with a single tank: either a filter bowl with a replaceable element (original design), or a disposable in-line filter canister (revised design). My truck has both types plumbed in, minus the element. I don't have a blow-up drawing, a parts list, or a description illustrating the duel tank option in my manual.

Was the duel tank option designed to use 2 filters?

I believe there should be a in tank screen filters for the low pressure pumps and all you need is 1 filter at the HP pump the other bowl you are looking at I believe is for keeping fuel to the hp pump it keeps air from getting in the fuel line when the tank gets low that could be your problem or check valve in pump turn off the engine with a guage on the fuel rail and see how fast it loses fuel pressure. I think it is called a accumulator or something like that.

Or the fuel pressure regulator
