48 chevy 1 ton gas tank

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.
