Loffen,

It's not that easy. The tanks have 2 baffles dividing the tank in 3 parts (center section, a left and a right section.
The corner opening on the baffles are not very large.

I've wander how a person would make sure that the tank sealer coated everywhere on the not visible baffled section.

Just thinking.



I haven't decided yet on the tank sealer vs just cleaning, the tanks don't have any kind of sealer in them from the factory so they should last another 40 years if they're not pitted to bad.

I could see the hardware and shake method on a motorcycle tank but the MH tank would be quite the dance...

Guys,
Check on youtube and look for videos for using Vinegar for cleaning gas tanks. Very good way to clean the rust out of the tanks.

Yes it is a terrible job, but it is working, I place the fuel tank on a bar stool or something like that and shake it for an hour or so (I is a great job for your wife or kids Wink ) then I let it stand over night and give it another hour with shaking before I clean it out (Yes it is a hassle to) when it is clean I mix hot water and baking soda to nutralize the vinegar and flush it a couple of times more before I place a heat gun in one of the holes for 20-30 minutes to dry it out.

If you do not want to use grawel or nuts and bolts you could use a chain and attatch one end of it on the outside, it does not work so good as the grawel but it is easier to get out.

I did not have an electric fuel pump to empty my tanks so I used a hand pump designed for transferring fluids. It did not take that long to drain about 10 gallons. Available at Walmart or auto parts stores for about 10 bucks. No risk of sparks and handy to have around.
