My 70 GMC had an aux tank mounted under the rear bench seat. Judging from the way it was plumbed and the fit and finish of the interior trim around the filler tube I believe it was a dealer added accessory. I don't really recomend driving around with 30gal of fuel under the kiddies.

My 72 sub has a 50 gallon tank the PO had installed, he was a member of an Air-stream travel club. i have the paper work and schematic of it, it is in stock location and the gas gauge works(kinda). it looks good and has the paper work for it so somebody was making them, i will take pictures after work and post them, along with the schematic and re-paint pictures.

thx Prairewolf, I would be interested to see how it fits, with a trailer hitch.

Here is onother picture of the gas tank, i guess my pdf. file is to big to send to this forum or something, i would send the drawing to a pm mail if any one wanted one.

thx for the PM, yes I would be interested in the measurements. gathering parts to build the SUPER HAULER. LOL

[prairewolf]

I will take good pictures from all sides and get all the measurements and post them, I will give myself a few days lead time, so i dont promise them over night and then drop the ball, It really is a well made tank, in the one picture it looks crooked but it is not,....... anybody who could box a frame could build one.
so finding a fabricator would be fairly simple i think.

Here are those travel tank pics and measurements.

the tank is 26 inches wide, it clears the frame rails by an inch on pass. side and a 1/2 inch on drive side approximate.

- is 37 inches long front to back on top, and 35 1/4 inches front to back on bottom. they extended the top I think to get more tank room above hitch.

- is 13 1/2 inches tall, except at back dovetail up is 10 1/2. dovetail starts to go up about 13 1/2 from back. I think it was dovetailed mostly for looks, I do not think it would ever drag.

the notch in top of tank starts 16 1/4 inches from front, is 4 1/2 in. wide, and is 5 1/2 in. down from top.

somebody reminded me to check to see if it was really 50 gallons. I went and put in 39 gallons, it was not empty. so i will say it has to be 40 something.

Its about 1.5 in. from sway bar so any extra gas room would have to come from the top down.
It looks like they tried to maintain fuel neck and lines as stock as they could.
I will always be more of a student then a teacher but i wanted to follow through on posting this stuff because i said i would. hope it may help someone....kent

It is going to run over $150 to fill that thing....

I have one of those old bolt-thru-the-floor 50 gal tanks on one of my burbs. AFAIK, they were aftermarket tanks probably available thru JCW and such at the time. That they hang low with no skid plate pretty much requres a hitch for protection if not a custom skid plate. They have no baffles so all that fuel sloshes around a lot. 50 gallons overwhelms the old, tired, original springs, especially on half tons. That's resolvable with custom springs or even add-a-leaves.

Still, they fit like a glove and hold a bunch of fuel for long range trips. They're made of ~16ga steel. Definitely not sheet metal, whatever the true gauge.

If you want one, try a wanted ad here in the classifieds or on ebay. I've seen them for sale. Expect to have to treat and seal the inside to prevent rust particles and gelled gas from ruining your trucks tighter fuel passages.

Great pics and measurments, prairewolf.

I don't know if you have found one of these tanks yet or not, but I just took one out of my sub. I am in AZ. Let me know if you are interested in learning more about mine.

Al, Here is a couple of pictures of the one in my Blazer.. I have no idea if is has baffles or not..

[cparsons]

I have a ??? guys...I just finished a 72 Blazer for my buddy's dad that has this tank in it...the only problem is the sending unit is bad and I can't seem to find one as he wants the gauge to work. Any ideas where I may get one?
