Stealth Fiberglass LP Tanks
Some time ago, some of the folks on these boards indicated that they were concerned about loosing their new Fiberglass LP Gas bottles, as they do not fit in the original Plastic Cover, leaving them exposed and subject to theft.
We badly needed to either re-certify our 2003 LD’s tanks, or get new fiberglass tanks. We opted for new tanks. However, I didn’t want to leave them visible, so I took a few measurements, and decided it could be done.
It turned out to be reasonably simple. The plastic base rings of the Fiberglass tanks fit (just barely) in the original steel frame for the metal tank base rims. However, the diameter of the fiberglass tanks is larger than the steel ones, so the original tank cover would not fit over the new tanks, without drilling out at least the two bottom rivets in the cover. Even then, it was virtually impossible to fit the cover back in place, and it forced the tank cover to stay open at the bottom. The problem is the cover shape. The cover is smaller for the last couple of inches at the bottom.
My solution was to cut the bottom of both pieces right at the point that the cover reduces in size. It then fit easily over the new tanks. That created a new problem. The tank cover was now about 2 inches shorter, and the threaded rod and the original tank hold-down clamp were also too high to fit under the tank cover.
That was solved by (1) cutting the threaded rod to fit under the tank cover, and (2) making a new tank hold-down clamp.
The last change was to bend the “ears” of the original “winged nut” up enough to clear the new hold-down clamp.
The new tanks are safe from prying eyes, and fully secured.
