Is this tank red because it is painted in the PHENOLIC ALKYD PRIMER paint?

Willys Jeep Parts Tech:
These tanks just have a rust preventative primer coat to get it through transit and storage. You will still want to do an official primer coat.

There were dimensional problems with these M38 reproduction tanks built by MD Juan. Supposedly the errors have been corrected. Are your tanks new production tanks or older stock? Is there a date stamp or decal on the tank to confirm its build date?

Willys Jeep Parts Tech:
These are new production tanks.

I have a m38 and we ordered a new gas tank for it. Now with the gas tank installed the drivers seat touches the gas tank. Is this normal or do I need some bushings of some sort to go under rear leg

Willys Jeep Parts Tech:
Take some photos so we can see what all you have going on. Happy to try to help.

My Jeep has a sediment trap in fuel line. Does that have a replacement filter that is used or just clean it out. (As you can see I haven't opened it as yet, but looks quite dirty.

Willys Jeep Parts Tech:
Depends on the style it is. You would have to inspect.

My 51 M38 is missing the gas tank so I will need to purchase all pieces but I don't see a filler neck on your site, are they available?

Willys Jeep Parts Tech:
Sure, we can get you all fixed up. Give me a call toll free and we can do so. 888.648.4923. Thanks

I have 1953 m38a1 which I am converting to 12 volts I need a fuel tank. Which tank can I use being that it has to be12 volts the tank that I have is no good so I would like to use a tank that is made out of plastic which tank can I use to replace the original one even if I have to modify it. I would need a 12 volt pick up system and sending unit.

Willys Tech:
If you have an M38A1 you need to stick with the M38A1 tank part number: 805605 and use part number:640694 for the sendig unit for 12 volt. It will screw right in. You may want to extend its arm a bit to read fully due to the M38A1's well.

Will this tank fit / work for a '55 CJ5 under the seat installation? I like the large mouth design and the look much better than the small spout of the CJ5. Also think it would be better for filling the tank with a Jerry can:-)

Willys Tech:
If you have a CJ-5 you really need to use part number: 912008. This is a totally different tank specific for the M38.

can the fuel sending unit from my 6v 1950 cj3a fuel tank (5 hole style) be used with this m38 fuel tank on a 12v setup?

Willys Jeep Parts Tech:
Yes, as long as you are using a 6 or 12 volt gauge in the dash.

I need a new tank for my 1952 M38. Do you also sell the fuel line that connects to the pick up and goes to the fuel pump?

Willys Jeep Parts Tech:
This is the proper tank for you. The part number for a fuel line kit is: MS00202

I was looking at the dimensions of this tank on your site. The measurements are a lot bigger then what I am pulling out of my 51 M38. Mine is about 18x24ish? Its the original gas tank. Which tank do I need to get?

Willys Jeep Parts Tech:
This is an OEM tank. Please email mike@kaiserwillys.com some pictures of your vehicle and tank and I can match up. Thanks!

What are the dimensions?

Willys Jeep Parts Tech:
Dimensions are 34x21x16 and weighs 25 pounds. Thanks

Hello, My 1952 M38 has been converted to 12 volt. Do you have a 12 volt sending unit that will fir into my M38's tank? Thanks and have a good one

Willys Tech:
640694 is the sending unit I would go with. It will bolt right in.

Do you sell the fuel pickup for this tank? I already have the sending unit for the small hole on the top of the tank, I need to locate the fuel pickup which fits in the large hole on the top of the tank.

Willys Tech:
Yes, the part number for the pick up unit is: M38FUELPICKUP
