I couldnt remember where I saw the mods for the fill neck and isnt there a mod to make the fuel tank vent better when filling? I think if you do this mod, you can get more fuel in it??
When/if you do the Hutch mod, while you have the sending unit/fuel pick up assembly out.. reach in the tank and cut the (ford) vent tube off (Harpoon mod).. you can then fill up.. without having to Dribble the last 5/7 gallons in... cuz the vent tube wouldn't letcha. (the Dribble factor)
AND... while you have the fill pipe disconnected.. to do the Hutch & Harpoon mod's... remove the three screws that hold the fuel fill port in-place.. remove it, jig it up in a vise.. use an 1 5/8" hole saw to cut that Small Nozzle Only.. restrictor thingy out. Clean it up real good and reinstall. THEN, you can use the Big Truck nozzles to fill up.. with no back splash, burp or beltch'n.. cuz the tank Vents like it should and the Big nozzles can be used.
