So I’m having fuel supply issue. I’m thinking I have a plugged fuel supply line. I have an electronic fuel pump mounted on the frame.

It was running fine then slowly started supplying less and less fuel until finally supplying none. I swapped out pumps and still same issue….. im
Think something is plugged form the pick il in the tank to the inlet side of fuel pump…
Best way of going about this? Already has All new rubber lines from the sending unit to the fuel pumped. I was going to try and charge the line with air and see if there was free flow?

Pull the inlet line off the pump put a piece of hose from the pump to a lawnmower can. Do you get fuel now. Well you just confirmed you can't pull it from the tank,but the pump works. No? You just confirmed you've burned up two pumps. External electric pumps don't live long most of the time. What brand? Where did you mount it? How did you supply power to it?Did you put a filter on the inlet of it? Are you running a return line? If the pump is verified to work, verify you installed it to manufacturers instructions,if so make sure all lines from pump to tank are in good shape and can't suck air. If all that checks out,you need to drop the tank 20 minute job if you have a cordless impact,a cordless drill,and some compound leverage cutters.

Well, factory is a in tank electric. When converted, did they remove the pump inside? If not, it probably still has a "sock", and it is plugged.

Well you are not using the in tank pump. So, did you remove the in tank pump, use a different year sender/pickup unit, or remove the pump, and just add a piece of fuel hose, or just slap the outside pump on?

I'm sorry I thought you were OP,asking us if they removed the original pump. I was like,What? How do we know what you/they did. Sorry. O.P. we need more explanation. Questions from post 2 and 4 and are you still TBI
