new or NOS m37 gas tank or substitute

I pulled my m37 gas tank yesterday to clean it and it is so rusty and has been patched so many times I decided I need to replace it.
I checked my vpw catalog and they don't list a replacement tank. Does anyone else make one? It does not have to be stock as the rest of the drive train was significantly modified before I got it. I use it quite a bit so don't want to try to seal the one I have
The penny patches are holding up pretty well but the other 13 patches are starting to rust through around the patches!!

I've used this stuff to resurrect a bag of rust in the shape of a gas tank:

It works great.

My son used a fuel tank from an '88 Isuzu Trooper as a replacement and it fit very well ('53 M37).

Bjorn,
I will try locating a Izuzu Trooper tank, thanks. Most junk yards in Colorado don't want to sell you a used anymore. Is that the same in other states?

Don't know, we have a parts Isuzu Trooper.....

I have the M37 tank as used in the M101 trailer for generator sets.. $400 here in VT...

I've also heard people using a tank from an S-10 truck fits also. They should be common to find in the junk yards.

If you run a 12v fuel level sender in the tank unit in the gas tank to the 24v gas gauge (12 volt truck) will the gauge read 50%??

Word has it that the s-10 is almost a perfect fit, right down to the sender location? The fill neck might need some adjustment?
My 2 Cents,

Anyone know which year model S10 tanks fit? I too am in need of a replacement tank for my M37.

I have a very nice original if anyone is interested...

More than likely it won't read at all and if you get the wrong sender it stands a very good chance of damaging your gauge. The gauges depend on sender resistance ranges from empty to full rather than on voltages. There are many many different resistance ranges in use and gauges that use them. The military long ago when laying out the groundwork for the M series decided to use custom ranges and values for their senders and so forth to keep folks from taking the stuff to use it on their tractor or stationwagon at home. Fuel tank senders for the standard M series gauges run a nominal 2 to 24 ohms. GM had at one time used a 0 to 30 sender but they are extinct and I don't remember if they were backwards from the military senders, 0 to 30 or 30 to 0 . An option might be to cut out the area of your present military sender and solder it into place on your replacement tank. Pull N Save costs a dollar to get in and Colorado Auto Parts is free, you might roam around with a tape measure and write down some notes on what might be the best vehicle or vehicles for your donor tank. Come on Craig, do some grunt work for us.
