A diesel fuel bleeder pump is an essential tool for anyone who owns or works on a diesel engine. It plays a crucial role in maintaining and repairing the fuel system, saving you potential headaches and costly repairs. This article covers everything you need to know about diesel fuel bleeder pumps: from their function and application to tips for selection and use.
What is a Diesel Fuel Bleeder Pump?
A diesel fuel bleeder pump, also known as a hand primer pump or fuel transfer pump, is used to remove air from the fuel system of a diesel engine. Air in the system can lead to starting problems, rough idling, and even engine damage. The pump allows you to manually bleed the fuel lines, ensuring the engine receives the necessary fuel supply. The operation is simple: by manually pumping, fuel is drawn from the tank through the lines and filter to the injection pump, forcing air bubbles out of the system.
Why is Bleeding the Diesel System Important?
Air in the diesel system is a common enemy. It can enter through leaks, filter changes, or simply running the tank empty. Without a functioning diesel fuel bleeder pump, bleeding can be a time-consuming and frustrating process. Imagine being stranded in the middle of nowhere because your diesel engine won’t start. A diesel fuel bleeder pump can be a lifesaver in such situations. “A properly bled diesel system is key to a reliable engine start,” says renowned auto mechanic Hans Müller in his book “Diesel Engines: Maintenance and Repair.”
