Gravity Fed Gas Tank
79 Short box F150 4X4: Trying to convert to Electric Fuel Pump and was looking for a way to convert to a gravity fed gas tank. Should I have a new fitting welded on the bottom or does anyone know of an original tank I can use to replace this one. Thanks for any ideas.

for a gravity feed tank to actually work (i.e. No Pump), it would have to be mounted above the carburator. I guess if you really dont care about what your truck looks like, you could mount the tank on the roof then run the line down the windshield.
I actually saw a farm truck equiped with one of these once

I assume that you want to convert your tank from a high feed, stock system to a bottem feed system. If this is the case, don't! an electric fuel pump will pull just fine from a stock pick-up. If the tank drew fuel from the bottom, all the sediment and other junk will fall directly into the fuel pump and damage it.

Thank you FE4ever,I may have been misinformed, Holley rep said I needed a gravity feed because it pushes not pulls. More homework required. Thanks again.

I'm sure that the parts guy mis-stated, or perhaps you mis-understood him. But all pumps push. that is just physics. but the action of pushing a fluid results in a vacume on the intake side. It is no diferent than a mechanical fuel pump. It makes no difference what power source makes the pump function, (electricity, or mechanical action) the pump knows no difference. as long as the electric pump is mounted lower than the tank, (just like the stock pump), it will work. My only question is whay not replace the stock pump? much easier, no new conections, etc.

I want a kill switch on the fuel supply. The only security worthy of trust, http://www.powerlock.com/ , doesn't work with seperate solenoids. I need to call Holley back. Oddly enough there was a perfect spot on passengers side where the fuel line diverted away from inside the frame, avoiding the exhaust, and changed from metal to rubber. Perfect splicing spot plus there are existing holes in the frame that lined up. Thanks for the info.
