Troubleshooting a stuck fuel pump

If your fuel pump is stuck and won't come out of the tank, it may be too big. This could be because the gas has expanded the plastic or the pump is a replacement that was put in with the tank off. It could also be that the pump is swollen. Be patient and keep pushing back and forth until you get an edge caught and can get it to come out. Try to bow it if possible. Once you get the edge caught on the side of the hole, you can push and bow it.
