Fill-Rite, the number one brand in fuel transfer pumps, meters, and accessories. We build AC fuel transfer pumps and DC fuel transfer pumps in the USA. How to Troubleshoot a Yanmar Diesel Injection Pump. Remove the lift pump outlet pipe from the injector pump with a wrench. Actuate the manual lift pump lever and observe the fuel escaping from the pipe. The fuel stream should be strong with no air bubbles present. Air bubbles indicate an air leak downstream of the lift pump and a weak stream.

Industrial Oil and Gas Fuel Transfer Pumps

For large operations such as industrial farming or mining, diesel fuel transfer pumps help refuel your equipment both safely and efficiently. Options in voltage, GPM (gallons per minute) ratings, and mobility can help you tailor your pump to the job at hand. Regardless of what kind of pump your machinery will require, ensure that you know how to find exactly what you need by understanding what to look for.

There are a few points to consider before purchasing your diesel transfer pump. First, think about the size and purpose of the equipment you'll be refueling. If you plan to refuel mostly automobiles or small construction equipment, a lower-flow model may be better suited than a large, commercial pump. However, if you do need it for more demanding use, such as in large-scale farming or mining, then you will need the increased pressure and flow of a higher-capacity fuel pump.

Though their uses are similar, the difference between lift and fuel injection pumps is important to know when selecting a pump for your equipment. A diesel lift pump uses pressure to raise the level of fuel, like how suction moves liquid in a hose. A fuel pump, however, doesn't only raise the level of fuel. It continues to pump fuel through the system. Currently, cars are made with fuel pumps that include lift pumps as well as several back-up modules. In these models, the fuel pump can also run on its own without the assistance of the lift pump in case of a failure. Therefore, though fuel pumps work with lift pumps, most do not need them to function.

Manual Rotary Fuel Pumps

If you already have a pump and need a new power supply, you will need the voltage specified for your model of diesel fuel pump. However, when looking for a pump, your use will determine what voltage you will need. For instance, consider whether or not you plan to transport your pump to different locations. You can find a 12-volt fuel transfer pump for either personal or commercial purposes. For larger commercial jobs, 24-volt diesel fuel pumps are available as well. For stationary standard uses, fixed pumps are commonly available in 115-volt models. Commercial pumps include 230-volt options as well.
