Know Its Job: The Fuel Pump

The job of the Plymouth Valiant Engine Fuel Pump is to deliver gasoline from the tank to the carb at proper pressure. This pump is mechanical and bolt-on to the engine in most of the classic Valiant models. It functions via a diaphragm system activated by engine movement, sucking the fuel from the tank and pushing it towards the carb.

Fuel pump plays a vital role and without it engine will not get constant flow of fuel and hence performance is lost or complete engine failure. Consequently, the fuel pump is an essential part of keeping older cars running.

Plymouth Valiant Fuel Pump Features

Classic Plymouth Valiant fuel pumps are characterized by a reliable and simple design. Carbureted engines need relatively high and consistent low pressure, which is what they are designed to provide.

Some key features include:

Mechanical diaphragm operation
