I had no plug so I had to loosen the wiring, connectors and tank straps then drop the tank onto a floor jack (after I pumped all the gas into a 55 gal. drum). Had to remove the fuel neck as well. Fuel pump came right out and new one popped in. Took about half a working day start to finish. If you have someone to help it speeds the job up considerably. Pump is a lot cheaper if it's the only thing you have to replace but if it's all ONE connected piece it's going to be costly. Be sure you have a quality jack and even some heavy duty jack stands.
