Dual / Single tank conversion
 
To renew an old thread here, any help would be appreciated.
My HP inline pump has been overheating, My thought was lack of fuel supply. Pulled line BEFORE Dual tank fuel reservoir assembly, grounded fuel pump on connector and got 8oz of gas in 5 seconds. Good in-tank pump. Reconnected and tested the engine supply port of the reservoir assembly, same method, 2 oz of gas. Bad reservoir assembly. The previous owner had removed the midship tank. QUESTION: can I take a fuel line from in-tank pump directly to the HP in-line pump? Do single tank F150's have a reservoir assembly, or some form of check valve? I don't plan on putting in another tank.

Yours is very similar to this diagram for an '89:

I put a new battery in. Now it does not start. It sound like it is not getting fuel. Maybe the fuel filter is clogged. The truck sat idle for a couple years...
