Helped a friend pull his gas tanks last Sunday. This GMC had sat for 11 years, and ended up with a coating of a gooey gunk on the tank bottom. Then rust up above the bottom. So I told him to used a Hotsy to clean the inside by way of the tank sender opening. Worked very well. Then put vinegar in for two days. During that time. Shook the tank around. Then a power washer. How need to use a small fan to blow air into it for a few days. Looking really good. Bob Dunahugh

I took the fuel tanks out of The Blue Streak to a company that strips car bodies chemically and they came back IMMACULATE!
Unfortunately one of them has been seriously attacked by metal eating rust worms and it's going to be a PITA to fix.

The top of the tank has condensed gue as well and it will get in the fuel
sooner than later, so do'nt thing it is a done deal.
We know this by experience.

There are lots of ways
To clean tanks.
The key item in a diy tank cleaning, is to get them back in and get them full of gas. Then keep them topped off for a while.
Vinegar may leave them clean, but a acid cleaned tank will flash rust worse then it was before you started in a short time frame. (Within a week)
At least that is what I have observed many times with motorcycle tanks, and I cant see gmc tanks any different.
