Had a sump welded onto my gas tank. For safety, the guy welding it flushed the tank out with water thoroughly, then did a fine job of welding it in place.
A year later, the rust flakes ruined one fuel pump and clogged a bunch of fuel filters.
I put an 8 gallon fuel cell in the trunk.
Now buying a new gas tank is on my list of things to do to make the Chevelle a street car again.
