1981 Ford F 100 Questions & Answers
My 81 ford f100 has a 302 engine. Im having trouble when i accelerate it acts like it is straining to accelerate almost like i have filled it with bad gas. I changed the fuel filter that is under the
There are several possible causes for this problem. Two of them from the newer gasohol fuel that was not used in 1981. I believe the trucks were the last vehicles to convert from carburetors to fuel injectors which originally were hybrid carburetors with injectors in the venturies.
The gasohol can dissolve the rubber valve in the front of the carburetors. The gaskets were not made for gasohol either. The rebuild kits for carburetors use a blue gasket which can handle the new fuel. The old gaskets swell and block the passages inside the carburetors.
You could check that filter you mentioned, seems like it is a low cost guess to replace as a possible solution.
Think about your past fuel sources, like where you could have bought bad gas. There are products like "HEET" which are suppose to draw moisture out of the fuel. It might help to try before you change filters and run the tank low with the additive and then put some good gas in; maybe a midgrade to insure octane rating.

Don't know where to poor my oil in my 1981 ford f100. there is not filler tube
there shouldn't be a filler tube, just a dipstick tube for checking the oil level. to put the oil in the engine, there should be a oil cap on the right hand side valve cover. if the dipstick tube isn't there, you definitely need to get one from a parts yard or store, you can be losing oil from the dipstick hole that goes to the oil pan...
