Got fuel tank lowered. Not so hard, used two ropes tied around frame and drive shaft. Removed to bolts on straps, removed straps, and lowered end closest to front of truck. Got electrical connector undone, but the plastic fuel line disconnect tool isn't strong enough. Luckily advanced auto around the corner has the metal one. Not as hard a job as i thought it would be. Thanks again to jbrew and others for advice and help.
