Recently finished a tub swap and now have a dilema. My old gas tank was an aftermarket one (of unknown origin) which mounted using long bolts down through the bed. After spending so much time & money on getting good sheet metal, I'm not thrilled about drilling out the "new" bed floor. It's a decent tank, ~40 gallons and I don't really want to toss it. How are the strap-mounted tanks secured? Do they have a recess in the tank to locate the straps? Just wondering if I could fashion some straps for my existing tank. Also I'm going to be doing a TPI swap, so was thinking if I do go the new tank route it'd make sense to get one with in-tank pump support. Anyone know of a place which makes 'em for Blazers? Thanks.
