I'm new to this whole resort thing. I got a 1948 Chevy Thriftmaster (1 ton) on a "barn find". I'm 0-19 in my efforts to find a gas tank (under bed) for it. Does anyone know where I can find one? Preferably new, but at this point, used will do.

Hello Trent, I haven't found a source for an exact replacement tank. I think your best bet is to place an ad here in the 'Parts Wanted' section. I've had pretty good luck finding things there.
Those tanks are difficult to find. I got lucky with my trucks in that good cleanings and a couple of small repairs were all that was needed.

You might be able to fit a behind the seat in there, new ones are available. Would have to make filler neck.

You are going to be hard pressed (near impossible) to find a custom fit tank for that 1 ton. If you're dead set on getting one back there, you are going to have to take measurements on the frame rails and find a fitted universal tank that will fit. In my opinion, just use the original behind the tank. If you have new hoses and a solid tank, the dreaded fumes don't exist. I have my tank behind the seat and I can't smell fuel.

The under bed tank became so hard to find we started making our own. A lot of people showed interest but we do not fabricate for any but our own projects so I did a write up on fabbing one up with home tooling. Not as pretty as the ones we do for shop customers with all our sheet metal equipment but it is cheap and out of sight anyway. Don't know on 1 Tons but on 1/2 and 3/4 the tank measures 13x13x21 inches. We use 18g cold rolled coated or 20g stainless which requires a TIG machine.

Common tools and using table edge to make bends:

18g cold rolled broke into a 13x13x21 box:

13x13 end plate with 1/2" flanges to fit into box section:

Pick up tube and fuel line fitting are brazed/welded into front end plate and pick up tube tacked to bottom of tank:

Would recommend anti slosh baffles before final end plate welded in place but not mandatory.

All seams are welded and frame brackets are fabricated. (pics if interested).

Is your tank missing? I have a 47 3600 and my tank looked like this. Not anything like a 1/2 ton. It measures 12x 7 x41. It sits under brackets from the left side frame. I was able to repair my tank as only the top was bad from dust sitting on the top.

As stated, the bigger trucks had different sized tanks. Here is a 3100 tank on a 1948.

🤪🤦🏼‍♂️

My apologies, Trent. I totally forgot about the 47-48 tanks being under the bed side.

I believe I have a good used original tank. You will probably need to coat the inside but there is no holes or rot. If you can provide measurements I can verify. Please PM me your zip code and I can get you a shipping quote.

Thank you and my apologies. Since the member is new and cannot PM I guess I will just post a for sale ad and hope they see it.

1947-54 Suburban gas tanks are available at the usual vendors. Don’t see any reason why a Suburban tank can’t be mounted and possibly modify the filler neck if necessary. Just an idea

I'm in southern MN. Zip is 56171. I am terrible at figuring out how respond/be notified someone answered me. My cell number is 507-236-5067. I just can't find one. I'm a farmer who is working on my 48 this winter. Please feel free to text or call.
Thanks.

Publishing your phone # on a public forum is not recommended. If you click on your username a drop down menu will appear. Click on posts and it will take you to every post you have made and you can see if anyone has responded. Looks to me like you have received 11 responses to this thread.

You are correct. I have no idea how forums or swap meets work. My apologies for being naive.

I have looked in the "swap meet" as I was instructed. I haven't seen anything. This forum is crazy confusing for me. I don't believe I have gotten any pm's as well. But I will say this, you guys are very helpful with your thoughts and I thank you very much.

Trent, in the upper right corner of the page next to your username you will see the image of a envelope. If that image is flashing you have a private message. Click on the flashing envelope to open the message. You can also go back to your profile and change your preferences to send you a notification email when someone sends you a PM.

One of the problems is the gas tank for the 1 tons is not being reproduced and used tanks are hard to come by, plus if you do find one it more than likely has had a visit from mister rust. Good luck.

Trent. Did you ever find a gas tank ? I am working on a 48 GMC 1 Ton which I suspect has the same tank. Unfortunately, previously in its life someone partially cut off the filler spout when a hoist was added to the truck. I have now removed the hoist and I am looking at fabricating a filler spout. Would it be possible for you (or somehow else) to post a picture of the gas tank filler spout? Note that there are no holes in the box (unlike the 1/2 and 3/4 tons) and hence I suspect that the filler spout goes up between the box and the back of the cab. Thanks.
