well, depending upon your diet I suspect. Original plastic tanks, properly
installed, have lasted for nearly 40 years. You going to need one longer
than that? Just asking.

Well I was thinking to make it a little more capacity as long it was happening. 1 3/8" deeper would make 10 gallons more so it would match the fresh supply closer. Some of the bus conversion guys are using aluminum fuel tanks as black tanks and seem OK with it. There was a GMC with an alum black tank in the description for sale awhile back. Cost compared to a new plastic tank is about the same. Just wondering if is a real bad idea.
