Hi,

I've just been looking at your website and wonder if you could help with my project. I'm currently restoring a WW2 SAS European jeep but am having problems identifying the fuel tanks used above the rear wheels. I think they are CMP made but for which vehicle i don't know. The approximate size of the fuel tanks would be about 31" long X 10" high X 11-12" wide, with the fuel cap located on the top of the tank on a very stub filler neck and also the fuel line on the top. I have also seen a lot of pictures with the tanks having no stamped 'X' re-enforcing to the tank ends like British Bedford type tanks. I have included some pictures of the tanks, if you can identify which vehicle they are from that would be great.

Best regards,

Tim Taylor

most of the CMP tanks I know of have the filler coming out of the side of the top and not in the middle like those ones.

Pictured is a CGT tank which shows where I mean.

BUT..... having said that there is no reason why Army workshops could not have modified the tanks to suit their new purpose!

You're right, though some earlier types had a top filler:

The tanks in the SAS Jeep seems not to have the prominent fuel sender cover, though. I wonder if these tanks weren't simply purpose-built?

tank size is 31 3/4 inch long by 12 wide and 10 deep. This looks to me like a pair of early CMP tanks. The location of the filler is the same as those tanks fitted to short bodied C8 and F8 and also I believe to 11 /12 cab quads with the fuel fillers set into the floor inside the body. The large brass cover plate on the very early tanks and the fuel change over switch were dropped fairly early on i seem to remember reading some where because its difficut to tell what the setting is, (ie if you are running on the reserve or the main tank) certainly I have been caught out before now with the C8. The fuel lift pipe is also in line with a other cmp tanks although the sender unit is not present? I wonder does a higher quality pic show it as capped off?...

anyway just my pennies worth

kind regards

Nick

On the Jeep picture there is no fuel sender unit fitted , CMP,s tanks have usually a Ford or GM sender in the top . But Early no. 12 cab Quads have a tank with the filler neck sticking out of the top, like on the picture.
13 cab ones have double capacity.

Ford CMP tanks also have a seam folded over on the long side of the tank on the top nearest the chassis. Not saying if the SAS tanks are Ford or not, but there doesn't appear to be a seam. This could mean that the SAS tanks are:
1. Not Ford, or
2. Not even CMP, or
3. Turned upside down with a new filler and pickup tube fitted to the BOTTOM?
I also don't see any strapping holding down the SAS tanks. How are they held in place?

In the thread Cab 12 FGT for sale , there is a pic of a Ford FAT fuel tank. You can see the Ford seam on the tank and the top mounted vertical filler tube.

The fuel tanks with the top fill location where common to both the Ford and GM Pattern 11 and 12 FAT. This required opening the door to refuel through a hole in the floor. Can you imagine pouring gas from a 5 gallon flimsy in the dark. There is a GM field service bulletin about problem of getting your hand around the filler cap because the hole through the floor was only 4” later increase to 5” across.

The Photos are from both the Ford and Chevy Parts books.

As to the fuel selector valve this is a stock fuel selector valve common to CMPs, They are still used on duel tank trucks today and are available from various suppliers. The only difference is in the handle which on CMPs was a cast part and now is a stamped steel handle.

Thanks, Hanno, Phil and every one who has helped with this thread, i finally got registered to ask the question on the fuel cross over switch myself, does anyone know of a supplier where i could get one from? i've tried all over....

The tanks on the jeep sure look like carrier fuel tanks

Keith Webb · #13 23-01-05, 06:46

Is this an Australian Carrier tank?

It's Ford, looks like it's a modified CMP tank, with a fancy brass filler.

Hanno Spoelstra · #14 23-01-05, 08:30

I'm still not convinced the SAS Jeeps were fitted with CMP fuel tanks, guys. In the pictures I've seen there are no clear fuel sender covers in view.
