Fuel pump is not pumping gas from fuel tank....

[OilPatch197]

I replaced the fuel sender about a year ago with a used unit. Today I started it up and was NOT getting any fuel, so I disconnected the mechanical fuel pump and installed a electric fuel pump, it could only pump a few droplets of gasoline!

So now I am not getting gas in the fuel line at the pump, so I am thinking I either got a pinhole in metal tube(the sender), a plugged strainer, or a crack in the hose at the sender. (OR a empty gas tank, but it SHOULD BE FULL the last I checked)

Would you agree that if I put my mouth to the fuel line where it connects to the pump, and I SHOULD be able to blow back, if not something is plugged. But If I can blow fairly easy, then I got a air leak.

Do you agree with this?

and what would be the harm of forcing compressed air back through the line to "maybe" unplug it?

that sounds right. i have serious doubts that your lungs could cause any damage whatsoever. if it works, you still may have to take the tank out and get the inside cleaned out really good though. just my $.02.

yea most likely a leak in the steel lines somewhere just sucking air I used compressed air to find a leak in an old mustang fuel line wont hurt but it will most likely find any weak spots in the fuel lines

Blew air through my dads and it unclogged it. But you may have to clean your tank out and get a new in tank strainer. Later we got a new tank for his truck.

Also: there is a product called Quick Polly that seals gas tanks if youtank is only questionable.
