Gas tank repair

admin

1939 Ford flatbed, put gas in and fuel line clogs. Drop the tank, rise out tank get half of a 5 gallon bucket full of crude. Look inside of tank tons of rust. Just can't clean it all out. What to keep the stock tank soooo. Cut the bottom out, now off to sand blast and and coating. Then weld it back together. Step one purge the tank hook up to a nitrogen bottle. Purge for 30 min. While purging, layout cut lines. Then use 3" cutoff wheel cut on my lines and take the bottom out.

Reply:I just saw the VERY similar tank de-rusted on FacebookThey took the tank, added enough gravel,,strapped the tank to the rear tire.Jack up the truck (enough so that the tank clears the ground)Start the engine, (with a temporary fuel supply)Let the tank rotate until you are satisfied that it is clean.  , hopefully, no welding, or purging required.
