Some block assemblies are supplied from the factory with a 3/8" by 7/8" bolt with (2) thick washers under the head allowing the OEM bolt to be re-inserted without the washers to secure the rod in place. Once the (2) fuel pump mounting bolts are tightened, the bolt securing the push rod can be removed and re-inserted with the washers under the head thereby preventing contact with the rod but sealing the hole. |
The longer bolt is to gently hold the fuel pump push rod in the retracted position- pushed in towards to center of the engine. | The longer bolt is to gently hold the fuel pump push rod in the retracted position- pushed in towards to center of the engine. | ||
