Hi Everyone

I have the bladder style fuel tanks in both of my M29c weasels. Was the bladder tank add by the Norwegian Army? Both tanks have an electric fuel pump inside the tank. Has anyone rebuilt one of these pumps? The tanks are stenciled on the top mfg by Firestone

Dan,

These tanks are actually called "bullet sealing rubber cells".

As the name suggests...they were designed to seal bullet holes in the tank. They have a "almost" liquid rubber center between the outer and inner rubber which will seal the bullet hole.

This change to the rubber cells came about at the same time as the in tank electric fuel pumps. This was a later Studebaker production change and not Norwegian .

IMPORTANT NOTE NEVER, EVER, EVER....USE GASOLINE CONTAINING ALCOHOL IN THESE TANKS !!!

The alcohol in gasoline will eat away at the rubber and soften it. Small pieces will separate and clog your fuel system. The inside of the rubber cell will eventually turn to a gooey mess.

Just another caution here........

DO NOT run the fuel pump without it being submersed in gasoline!

Gasoline lubricates the pump and running it dry will damage the pump internals. It is OK to do a very quick test to see if it works when dry but never run it more than a few seconds.

Also...this pump is basically the same as the pump in the M-18 Tank Destroyer and the M-135 & M-211 GMC 2-1/2 ton 6x6 trucks. Those pumps are 24 volt but the internals are the same.

Rebuilding of the electric pumps is covered in a carburetor and fuel pump rebuilding TM available from Portrayal Press. I don't remember which TM number it is but Patrick should be able to tell us.

Just look in your TM 9-1772 Weasel manual on page 127 and there is a photo of the cell. In addition , pages 126 to 140 cover the fuel cell and how to inspect and repair it.

If you guys don't have that TM.....you REALLY need to have it as it covers the repair/rebuilding of the major components of the vehicle !!

Of course you can get an excellent printed copy of it from that Portrayal Press outfit...............
