Hello. That fuse is in one of two places; in the main fuse box on the driver side in the cab or on the left front inner fender. Good luck and keep me informed; if you want to.

Sounds like the selonoid at the switching valve is not working.

tank sizes are figured out by the cab style and bed size

what type of timing advance does it have? vacuum etc. you need to disconnect advancing circut to complete this task

Every time I run into a starter problem the first thing I check is where the wire meets the battery terminal for corrosion and of course the grounds.

It could be a fuel pump problem. If it isn't working correctly the engine is having to siphon fuel from the tank to the carburetor in the morning, which takes forever. The longer it sets, the fuel will eventually go back to the tank.

check the plug wires and the distured to it sounds like its not getting fire

YOUR FRONT TANK INTERNAL FUEL PUMP IS WORN OUT REPLACE IT

A FORD EQUIPED WITH DUAL TANKS THIS YEAR MODEL HAS CHECK VALVES IN THE FUEL PUMPS .THE FUEL RUNS FROM THE REAR TANK WHEN IT IS POWERED ON TO A TEE AND INTO THE SAME LINE AS THE FRONT PUMP . THE PROBLEM IS AT THE BOTTOM OF THE FRONT FUEL PUMP THERE IS A CHECK VALVE ON THE FOOT AND IT IS NOT WORKING.WHILE THE TRUCK IS RUNNING WITH THE REAR FUEL PUMP ON IT IS PUMPING FUEL INTO THE FRONT TANK . IT WILL RUN OUT OF THE NECK WHEN IT IS FULL.THE FIX IS SIMPLE REPLACE THE FRONT FUEL PUMP. THEY DONT MAKE A CHECK VALVE REPLACEMENT I CHECKED I HAD THE SAME PROBLEM AS YOU.

the switch should be under the radio on the right side of the ac controls its a toggle type switch up and down
