What a bummer
. Shop got it up on the hoist and found there were holes rusted through the steel lines coming out of the tank. That is separate from the pump, and is a GM-only item that I could find

Interchange book said only 98-99 SC GP, Bonn, and maybe a few others, but somewhat limited usage. Moral of the story, keep the under carriage clean in the saltbelt.
