I could be the hickey, I saw picture of that somewhere, it's similiar, but looked a bit different. Mabey they had different models. Dunno, this one has a skid plate built into the bottom of it as well, it has a beavertail on the back...it's 50 gallons almost exactly, when I had it-renu'ed, (before I tore the truck down to it's current condition which is still being built with glass body and all..), from bare empty, I remember I put a full 5 gallon gas can in, drove 3 miles down the road to the gas station, and it took just over 45 gallons more. The renu is supposed to take a bit from overall capacity as well, my 20gal chev pu side-saddle exploding tanks were 19.8 before renu and 19.0 after...I do tend to "fill" it up (gotta test that send unit 0-ring you know)...
the renu guy told me never to lose that sending unit, you'll never find one to fit it if you do, he said...
