Selector Valve

I have an 88 F150 302. I have a single fuel tank but there is a Tank selector housing still on the truck which i believe is holding the only fuel filter as there is no other filter anywhere(confirmed by a mechanic) My question is can i remove the selector and put a proper filter on the truck? I bought the truck in this condition im just tryin to fix another Backyard mechanics cluster#@&%

You should have an fuel injector filter mounted with the high pressure fuel pump in 1988.
Did this truck have two fuel tanks at one time?
If no then that is not a selector valve on the frame. It is a single tank reservoir and may or may not have a filter in it. With one tank you should keep the single tank reservoir as helps supply fuel to the high pressure fuel pump under times when you have high fuel consumption as in WOT.

Your fuel injector filter should be as in the photo below. It is inside the bracket and not as obvious as newer trucks that have it out in the open on the frame.

The filter in the container on the frame is just for the high pressure fuel pump and is not a injector filter.

No because as I stated above it is a fuel reservoir for the high pressure pump. If you put a filter there you still would not have and injector filter after the high pressure fuel pump.

If it is a selector valve then I would replace it with a single tank reservoir.
The single tank reservoir:

I don't see any evidence of a second tank so your correct on the Single Tank reservoir So this truck has the Reservoir then what looks like some excess fuel line then the HP Pump I've decided to splice a filter into the line today no idea why someone would remove the filter but its my problem now.

Did you look inside the bracket for a filter?
I would not go by what the mechanic told you on an older truck as he may have not knew where to look for it.

So, subford, on a 2 tank system, the selector valve would replace the reservor ? This is great info. I'm working on this over xmas break.

Yes and no.
The selector valve for the two tank system has the reservoir it it at the bottom for the 1989 and older F-series.

I realize this is out of my year model. But if there had previously been 2 tanks, there would have been a front/rear toggle switch in the cab to switch tanks in your year right?
