ill see if i can lower the tank and see if there is a access for a internal pump, but so far i havent found any wire or hosing that leed to the top of the tank at all, my manual says there isnt one installed just the external pump.
Ive already rebuilt the carb and the accelerator pump as well as other diaphragms were replaced, i had talked to a carb mechanic a while back and that was one of the things he suggested.
Those specs are the specs from the factory, i dont have a way to test exactly what it is doing at the moment due to lack of funds.
There is a pump in the gas tank, as there is not a mechanical engine-mounted pump available that can draw gas from 18 feet away and 3 feet lower than the carb. There is no fuel pump on the engine, either. Be sure to get the right pump, based on the year of the driveline, NOT the year on the title. In 1987 Fords changed the gas gauge resistance, so by installing the wrong pump the gauge will register empty when full and full when empty. I should know, I have one just like yours, with a 1986 driveline with a Holley carb.
The pump you claim that is under the vehicle is actually a fuel filter, be sure to replace the element inside, which is available at NAPA.
I am really curious as to how your carb guy didn't notice that your engine is fuel injected, Ford switched to FI in 1987.
