I'm not sure what your level of comfort is with being under your car, but as
you can see you're definitely headed for a possible "I need to drop the
tank" scenario.

I was pretty freaked out at the idea of removing and replacing the gas tank,
but I was under my donor van trying to extract some hydraulic lines on
Saturday, and I think I've decided that taking the tank down is going to be
a lot less work than figuring out how to get the hydraulic clutch line out
without taking the tank down.

Also, although I don't think it will matter because my donor van is probably
not ever going back on the road, while I was thus engaged I noted that the
fuel lines appeared to have been "done" already--meaning someone had
replaced them...but when I reached up there to try to figure out what the
clutch line was hanging on, I felt what I thought was an old, broken up,
dryrotted piece of hose, which I only found by reaching up into the saddle.
 I would therefore echo others who are highly recommending taking the tank
down to anyone who is considering doing this for the first time.

Here is a write up on just taking the tank off:

Although I haven't done it, this guy claims that it's only a 2.5 on a scale
of 1 to 10 (10 being an engine swap/rebuild).  He has a whole reconditioning
procedure:
