Fuel Pump Push Rod

The fuel pump pushrod is a device that connects the lobe on the camshaft to a lever.

Fuel pump pushrod function

The fuel pump pushrod can float similarly to a valve spring when the engine speed increases. The pushrod is usually set up on mechanical fuel pumps and is controlled by the eccentric placed on the camshaft. As the engine and camshaft rotate, the pushrod causes the fuel pump lever to go up and down, taking in fuel from the tank and transmitting it to the carburetor. It is important to note that if you have low pressure you should inspect the fuel lines as well as the filter.

Common issues with a worn fuel pump pushrod

A worn fuel pump pushrod can lead to difficulty removing the pushrod, poor lubrication, or a decline in fuel economy.
