I've got an 82 F-150 with a 351. Wasn't paying attention and ran it out of gas. Filled the tank up and now it won't start. It has an electric fuel pump and I thought maybe it was weak so I replaced it since they're cheap. Replaced the in line filter as well. I'm not getting any fuel to the carb. It'll run with starting fluid but why am I not getting any gas to the carb? Do I need to prime the system some how?

Priming the system is as easy as turning the key. The pump should come on for a few seconds right after the key is turned. That should fill the bowls of the carb almost instantly.

Are you sure that the pump is coming on? Also is the filter keyed? Or one way only? It could have been put in backwards.

But yes, fuel related if it'll run on a shot of ether.

The pump comes on, the filter is on the correct way but it's not getting any gas up to the carb.

You can remove the line to the carb and have a helper turn te key on and visualize the gas coming out of line and then reattach.

Not sure what carb you have.

I'm not even getting fuel to the pump, so I know it's not making it to the carb. I've pulled the line off after the pump and not getting any gas. Is there a pump in the tanks as well? Or an in tank filter?

I looked on Rock Auto and it looks like it comes from the tank through the sending unit to the pump and then to carb. So at this point your sending unit might be plugged. Do you have any way of sucking on the sending unit without using your mouth?

You might need to jolt it up into the pick-up.

No pump in tank until FI engines 85+. (Some F250+ have tank pumps but not F150).

Do you have dual or single tank?

The sender in tank should have a 'sock' filter.

stevebuchta

It's a dual tank truck... So possibly a clogged filter in the tank or a clogged pick up in the tank?

klricks

Or the tank selector valve and/or wiring/switch is broken.
Are you sure you have the switch set to the proper tank?

Any updates?
