This refresh kit and a good cleaning is pretty much all you need if your pump is in good condition. The check valves in these fuel pumps can normally be flipped upside down and reused. 


Please study the above picture of the type of fuel pump this gasket set fits to make sure it looks like yours It is an AC Model B and has the bolt on stem/actuator shaft.

The AC model B fuel pump will fit many applications including Chrysler/Dodge/Plymouth of the thirties to forties and Dodge trucks from the thirties to the sixties plus some industrial applications. The main differences are fuel inlet and outlet locations whether straight in and out or 90 degrees to the fuel pump, location or the placement of the fuel pump cover on the lower mounting housing and/or the configuration or type of the camshaft rocker arm.

This is a fuel pump gasket set with diaphragm and screen to fit vehicles and antique trucks using the AC Model D fuel pump. This kit fits the old style fuel pump that has check valve retaining nuts on the top cover and a 3 bolt spring cover on the bottom housing as shown in the picture of the complete fuel pump. The break down of the fuel pump shown is for an AC Model B fuel pump but the AC Model D fuel pump is of the same construction except for the 10 bolt instead of a 6 bolt diaphragm. Kit comes with a complete instruction manual on how to rebuilt the fuel pump.

The pictures of complete fuel pumps are for reference only and not for sale. These pictures show you what your fuel pump should look like although the location or orientation of the cover to body may be different.   

There is a replacement fuel pump that was made that uses one piece unitized check valves inside the fuel pump and the diaphragm is swedged on instead of bolted on the actuating rod. This kit will not fit a fuel pump with a swedged on diaphragm

The diaphragm in this kit has an outside diameter of 4 inches and uses 10 screws to retain it between the cover and the body.

This kit includes modern nitrile diaphragm that handles today's fuel types, 3 bolt spring cover gasket, glass fuel bowl mounting gasket, fuel pump mounting gasket and brass fuel bowl screen as shown in the picture. ALL NEW reproduction; spring cover and fuel bowl mounting gaskets are NEW high quality rubber impregnated cork, engine mounting gasket is high quality paper.
