What parts fit from a 1994 to 1991 f150

fit a breather to the inlet pipe of the tank.

Okay I've had my Ford Truck for coming up on 18 years, and well it's been great truck... That being said I will say troubleshooting a Ford with all the issues around the electronics, relays and ect. can be a real pain... Make trip to junk yard and get few things.. 1st try swapping out fuel tank selector switch, then fuel pump relay... switch is in cab and relay is in engine compartment on drivers side... if neither does it i bet you anything its the computer itself.. mine was acting up it was doing same thing for awhile.. when that computer starts acting up the problems can vary and all together change... makes troubleshooting next to impossible good luck.

Fords were pretty interchangeable, I believe there are parts from trucks 87-96 that fit such as beds, doors, mirrors, etc. As far as engines and hardware go everything should be changeable. The 5.8 was one big one whether its the modified, the cleveland, or the windsor. Also the 5.0 (302) from Mustangs or trucks could be interchanged pretty simply as long as you used the original transmissions.

should be an easy swap if you are using the same size engine. 302-351 then you will need to do some changes.

I understand that the sending unit is the sensor,if im right,look for it in the engine,where the top hose of the radiator is connected to engine,around the part you are going to see the sensor .

sounds like your old mounts were going bad. The rubber parts can degrade over time, especially if they get oil on them, which it almost certainly has at some point. This is a fairly common occurrence, so it's nothing to worry about.

IF MY MEMORY SERVES ME RIGHT THE 5.0 IS A SMALL BLOCK AND THE 7.3 IS A BIG BLOCK. IF THIS IS THE CASE NO THE TRANY WON'T BOLT UP

Go to an auto wrecker. Take the broken one with you and try to find the right one. Somebody may have changed the head or the whole motor on that truck at some point. Maybe you're getting the wrong parts because of it.

that is easy to replace if u can do all that u can remove 2 scrws lol right on top on enggo to parts store and get part and if they told u 40$ thats cheep more like 70.$

Sounds like its Not Advancing this is Electronic and if you mix match parts this way these are the problems you run into sir I can not Advise you on a Repair or fix As it is not All STOCK FACTORY EQUIPMENT So Sorry
