Its in the fuel tank - is part of the fuel guage sender unit and accessible from the front of the tank. I don't think its an easy job to remove and replace without using a manual (borrow from library). Maybe do a search on this forum as removal has been covered many times. Good Luck.
Did one the othe day easier to do on a hoist if U can get use of one U have to drop the tank straps and the pump is at the front of the tank. not hard to replace the pump, just a pain with having to drop the tank straps etc. Good luck
U have to remove the float while unit still in the tank as the sender and pump will not come out with the float still attached. And the same to refit put senderand pump unit inside the tank then side float in and connect. Stupid idea by Holden But...
