Fuel tank woes

[TimberHole]

I can’t understand why your current tank cannot be cleaned. Did they use a light acid like vinegar? Did the fill it with nuts and bolts and then tumble? A slosh coat should encapsulate anything that remains. To me, the only reason to replace a tank is if it is leaking and can not be repaired.

we used to put a piece of chain in the tank and spend some time shaking it around. when its as clean as possible took it to a radiator shop to have it boiled out. then after flushing it with clean hot water and fully dried put a can of tank sealer in it.

I have cleaned a few gas tanks and found that after getting it as clean and dry as I could dumping in about a quart of WD 40 and sloshing it around real good was good insurance against any residual moisture. For the younger group here, WD 40 was developed during WWII as a water displacement formula for equipment being shipped over seas.

There were several companies competing for the govt. contract but a company in San Diego,Ca. came up with WD 40 and won the contract.

I'd take it to a radiator repair shop and have it boiled out. Then some tank sealer. Just like Rebeldad1 said.

I dont understand where all the debris is coming from? Is the tank so rusted and rotten that it is still flaking off chunks inside? Or is there a problem with the fuel going bad, or is there moisture or bugs and dirt getting into the tank?

Fuel tanks are quite susceptible to condensation. Any enclosed space vented to atmosphere accumulates condensation.
