20 years sitting in a barn. I do not want to, but I feel that I must do
this. The rubber lines are sure to be dry rotted, and there's a good chance
that the tanks may be full of rust or something.
The tanks need to be inspected, yes? And I must drop them to do this, yes?
And I need to drop them in order to replace all the rubber anyway, yes?
I think I will buy some 2x12s and build a ramp that will put the bottom of
the tires a foot and a half off the ground. That will give me enough room
to get underneath and do things.
I will be doing this in the driveway of my house. The weather is pleasant
enough, there are no wasps, and it's convenient. I might ougt to "strike
while the iron is hot" as they say, especially since my dear sweet wife is
so enthusiastic.
Comments or suggestions? I believe the tank dropping procedure is in X7725
somewhere? It wasn' tin the main manual that I downloaded, I need to go
find it. I would love to hear some been-there-done-thats from those that
have done this before already. Comments, suggestions, attaboys etc are all
welcome. There will be video.
Hoses will be replaced with corn-proof hose.

I use 4x4s (because siomeone gave me a truckload of them) but whatever, crib the thing up solidly. Not like you had it in the pic waiting for the brake mechanic. If it falls on you, you ain't coming back out from under it again.

Robin,
I took the coward's way out on the coach and had Jim K's folks replace all the soft lines. (My best tool is my checkbook.)
However on my daughter's Vanagon Westfalia, that had been sitting for 21 years, I replaced the fuel tank. I anticipated a heavy tank full of old fuel, however it had no liquid in it at all. I suspect it had evaporated, and the result was a tar-like goo that remained. For the GMC I would recommend finding a local shop that can boil and coat the tanks.
I would not get stuck in the "while I'm at it" game (too much.) For instance adding electric fuel pumps, though it will be nice to do at the time, is not in line with the primary goal of getting her on the road. A large fuel filter might not take too much time and might be beneficial, though if the tanks are cleaned and the hoses are new the need is lessened.
Here is some - while you're at it stuff that might be worthwhile - I really like the things guys are doing with port-holes in the floor so that they can access the tank opening. This would enable you to add the in-tank fuel pumps at a later time if you choose to. If any of your steel lines are clogged, corroded, or you just want to replace them, I would recommend PolyArmor < http://www.agscompany.com/automotive/brake-fuel-transmission-lines/poly-armour> It's very easy to work with, corrosion resistant, and should be available at your local Napa Auto parts, though they may not know it by name.
Don't forget the vent lines, the generator supply line, and the vapor canister and separator. Some have removed the vapor canister, I think it's a good thing to have. The idea of collecting fuel vapor when sitting and then sucking it into the carb to be burned is a good thing. The supply side has to be looked at too. Once all of this is back in place you'll be able to set the nozzle and fill the tanks whilst enjoying a cool beverage. Once the coach is running I expect you'll this quite often!
Good luck to you and enjoy the ride!

Yeah, my thought, too. You're the guy who was going to ship the coach off as a Burning Man sacrifice, right? If so, this is a big shift in trajectory and may need some "good times" logged in asap. That said, breaking down isn't a good time for anybody ..except maybe Ken H.
So maybe slush the tanks, replace the fuel lines and filters, mark the spots in the floor for access ports and take it around the block a few times, then out to a nearby state park or rv resort.
That's the best-case scenario, though, because the average rebooted vehicle soon starts to shake out some other problems. Whatever you do, I'd keep the wife appraised of the risks involved in having an adventure involving vintage vehicles.

Robin,
The 20 year old lines are NOT compatible with ethanol, neither are 35 year old lines! ;-)
I think ramps that are 1 1/2 feet tall are a bit ambitious for a GMC to climb. Even with the air bags fully expanded I don't know if
you'd be able to clear the body sections behind the rear wheels. I assume you would be backing in towards your house to get up on
them and that would be a bit scary if something went wrong.
I just measured the ones that John Sharpe built, they are 8" high, 10" wide and 72" long and HEAVY!
I could have sworn that you had a set of wooden jack stands when I was over there helping you with the rear brakes. Why don't you
use them? If you want them higher add a few extra "steps."
Regards,
Rob M.

I dropped my tanks pretty soon after I got my coach. It leaked out a line on top when the PO filled the tanks for my test drive. I built these ramps http://www.gmcmhphotos.com/photos/wood-ramp-construction/p5006.html
They are long and heavy, and I used treated wood, making them heavier yet. But short of a pit/lift, I think they put things at about the perfect height for laying on your back and working. Too high is a strain, makes for too far to steady the drop, and gets you in the position for more stuff to fall in your face. I love the rams, and they give me plenty of room to do what I've needed under there. I do most of my work outside on the concrete pad in front of my garage.
The tanks came out pretty easy with some vice grips and electric impact wrench, couple pieces of plywood and a floor jack. I pumped out all I could, and it was a handful but I got them off and on myself; I need more friends who have my same work schedule.

Rob "Safety Officer" Mueller persuaded me off-list to just go with the 8
jackstands I've already got instead of building expensive and heavy ramps
that will be hard to store. :)

I used this lift to remove my tanks.
http://www.harborfreight.com/1500-lb-capacity-atvmotorcycle-lift-60536.html
It requires enough clearance to slide under the coach with the handle
removed. Is good for removing bogies too.
