Before you start the process, fill up, and if you know how far you can go on a tank, run it pretty close, then drop the tank. . It is a pretty simple process, once you get the tank dropped. I did mine a few years ago, and have not had any problems since (knock on wood!). . If you need any help, feel free to PM me, and I can do my best to coach you, if needed! Best of luck, and get that darn thing working again!!! hehe
