1934-36 Chevrolet Low Cab Gas Tank Changes

Monday, June 29th, 2015


If you have one of these unique low cab Chevrolets (made about 6 months) you might have not realized there are two gas tank locations.

For ½ tons (116”WB) the 16 gallon gas tank was positioned between the frame rails and just behind the rear axle. The mechanical fuel pump on the right side of the engine pulled the gasoline about eight feet distance to the carburetor.

A change was made with the 1936 low cab 1 ½ ton trucks. Chevrolet continued to realize it was not acceptable to have the tank so far from the fuel pump on a long wheel base. Therefore, a 17 gallon tank on both the longer 131” and 157” wheelbase continued to be placed under the seat cushion.

Remember: The cabs are almost the same on the ½ and 1 ½ so the only universal place available was below the seat cushion! On the longer wheel base 1 ½ ton trucks the passenger door was opened to get access to the gasoline fill that was inside the cab. This had been the way to add fuel since 1934!

The late 1936 1 ½ ton (low cab) were all the same except in the gas tank related area. Here is why!

EDITORS OPINION: In 1936 and earlier, the USA was experiencing the height of the Great Depression. Car and truck sales we show and most everyone was feeling economic slowdowns.

General Motors looked for ways to cut expenses, especially on truck production. They were workers not pleasure cars. A perfect example is changes on the 1936 Chevrolet 1 ½ ton. The new truck under seat gas tank was planned due to complaints and a side fill added. This would eliminate the inconvenience of raising the bottom seat cushion to add gasoline. Unfortunately, so many of the older designed tanks remained stored for future truck production. GM was not about to dispose of these new tanks during the depression so they used them until their supply was eliminated.

It was much less expensive to be ready for what was coming later in the year. It was a matter of economics! Therefore, the stamping in the right seat riser and scoop in the inner door panel was part of the 1936 1 ½ tons. When the extra tank supply ended, it would be inexpensive to have the truck ready for the new design.

We thought this might be of interest to the perfectionist with a 1936 Chevrolet 1 ½ ton low cab.
