Does this gas tank come primed on the outside ? From the pictures it looks like it is already has primer. Would you recommend coating the inside since many fuels may come with ethanol ? Thanks

Willys Jeep Parts Tech:
Yes, it comes primered on the outside. WE never coat the inside. As long as you use non-ethanol fuel you will not have a problem.

Is the interior of the tank bare steel, stainless, or coated with a rust proof material?

Willys Jeep Parts Tech:
I believe they are uncoated. but if you keep nonethanol fuel in them they will not rust.

I've acquired a 42 MB with a major amount of custom work. And that includes the fuel tank well. What are the dimensions of the tank. Specifically the area that sits in the well?

Willys Jeep Parts Tech:
Length 24-5/8" overall Width 18-1/2" overall Height 11-3/8 overall Length of stepped portion 13" Height of stepped portion 6"

Dose the tank come with filler cap or do I need to order separately?

Willys Jeep Parts Tech:
The gas cap is separate.

What is the correct Fuel Tank Sump to fit this fuel tank and a ´42 MB?

Willys Jeep Parts Tech:
A3497E is the proper well for your early Willys MB.

does this fit a 1940 willys jeep?

Willys Tech:
They really didnt make Willys Jeeps in 1940. None that arent in musuems at any rate. Please call us toll free. We can help you ID your vehicle.

What would be the capacity of this fuel tank? Thanks.

Willys Tech:
15 gallons just like original

What is the diameter of the small and large mouth filler hole? My MB doesn't have any thing to indicate its year of manufacture.

Willys Tech:
The small cap is really small like 2 in diameter while the small one is around 4 in diameter. It will be realy obvious when you go to take the cap off. Really big or really small for a gas cap.
