Description

237-155 Tillotson Inlet Valve Diaphragm is the actual works as a check valve for the carburetor. 

The High Volume, or what is known as a double-stack, has its fuel pump diaphragm separate from the fuel inlet/check valve diaphragm. The design is the reason for the additional plate and different designs. 


This diaphragm is what you will hear us call a "snakeskin" diaphragm as it resembles a snake's skin is actually a Polytetrafluoroethylene(PTFE, Teflon®) material. 


It is common for carburetor builders to convert gas carburetors into running methanol, which usually means changing the carburetor's pump stacks. We highly recommend buying a complete EC Pro Gasket or Rebuild when converting. This pump is also required to make the conversion to use the high-volume pump plates.
