80 250 fuel pump
I have an 80 f250 and it has some fuel issues. I have decided the fuel pump is my next step, it's an inline set up, what should I be looking for psi wise. It's a 400 all stock by the way

Around 5 psi. Another good test, take the line off and put a rubber line on it and put it in a bucket. Crank the engine over, it should send strong spurts of gas into the bucket when the engine turns over.

If this truck has been on the road and running on a regular basis, I would wait and do some more testing. If you just drug this thing out of a field or a backyard where it has been sitting for several years, I would go ahead and replace the pump. The ethanol fuel is bad on the fuel system when it sits around. The fuel pump and the carb will probably need a kit also.

Ethanol fuel or not, if the fuel lines are degraded then their is good chance the fuel pump diaphragm is also degraded. They don't last forever, a good rule of thumb is every 5-8 years replace it, it's cheap insurance to avoid being stranded or it puking fuel all over the place when the diaphragm fails.
