Description

237-255MYL Tillotson High Volume(Double Stack, Alky) MylarFuel Pump Diaphragm is the diaphragm pumping fuel for the carburetor. 

The High Volume, also 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 made of Clear Polyethylene Terephthalate(PET, Mylar®) used on many of our built carburetors. 


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.
