Lift pumps have several applications beyond automobiles and are also used in sewage systems to pump out waste from a full sump pump. A lift pump can be defined as a low-pressure pump whose core functions is to transport fuel to a high-pressure pump.

Fuel lift pump diesel engine. A diesel fuel lift pump is a lift pump that transfers fuel from the tank to the fuel injection system. Because in modern vehicles the tank is located below the engine the fuel has to be lifted up from the tank to the engine which the diesel fuel pump does. Three types of lift pumps common in light vehicle diesel engines are the diaphragm-type.
Practically every diesel engine has a fuel lift pump. It lifts fuel from the fuel tank and primary fuel filter then pushes it through the secondary fuel filter and into the fuel injection pump. A few engines are fitted with electrical lift pumps which are almost always sealed and cannot be rebuilt but must be replaced when they fail.
Lift Pump Purpose. The Fuelab Velocity 200GPH fuel system uses a lightweight high-flow brushless DC motor to ensure long pump life especially when used with todays Ultra Low Sulfur Diesel fuels. Anytime you plan to pursue more power than what your truck made in stock form a lift pump is a good idea.
Because the injection pump and injectors are arguably the most vital components in a diesel engine keeping them supplied with plenty of fuel keeps them cool lubricated and functioning properly. Lift pump assemblies bring fuel from the fuel tank up to the fuel pump via filters. Lift pumps are part of a more dated construction of diesel engine as modern day common rail diesel engines use either electric or vacuum pumps to deliver diesel to the fuel pump.
There are many varying types sizes and manufactures of lift pump assembly but the most common manufacturer is. 1- Displayed below for identification purposes are the most common Fuel Lift Pumps used on some popular Perkins Marine and Industrial diesel engines as well as Cummins Marine Engines. 2- Please use the corresponding reference number when calling for a replacement pump or parts.

Pacific Performance Engineerings Diesel Fuel Lift Pump is capable of pumping up to 160 gallons of fuel per hour it is compatible with bio low and ultra low sulfur diesel fuels.
The Pacific Performance Engineering Diesel Fuel Lift Pump is a key component to a reliable fuel system. The primary fuel or lift pump moves the diesel fuel from the tank into the fuel system and provides the initial fuel pressure. Designed by Perkins to ensure the correct flow rate and pressure to prevent the cavitation and vaporization that can lead to damage.
The main job of a lift pump is to draw fuel from the tank and supply pressurized fuel to the engine. Just about every diesel has a lift pump of some sort from the old mechanical injection systems to newer common-rail rigs. Most lift pumps OEM or aftermarket provide between 6-to-65 PSI worth of supply pressure depending on the application.
Lift pumps are part of a more dated construction of diesel engine as modern day common rail diesel engines use either electric or vacuum pumps to deliver diesel to the fuel pump. There are many varying types sizes and manufactures of lift pump assembly but the most common manufacturer is AC Delco who were an original equipment manufacturer.

What is a Lift Pump. A lift pump can be defined as a low-pressure pump whose core functions is to transport fuel to a high-pressure pump. In older engines fuel pressure is directed into the injection pump where higher pressure boosts it through an injector.
The case is slightly different for new engines that are electronically controlled. A diesel fuel lift pump is a priming pump that transfers fuel from the tank to the fuel injection system. They are called lift pumps because in most equipment the tank is located below the engine the fuel has to be lifted up from the tank to the engine.
Simply put a lift pump is a supply pump that transfers fuel from the tank up to the engines injection system. Virtually every diesel has a lift pump of some sort from the old mechanical injection systems to Fords HEUI system to newer common-rail rigs. In automobiles the fuel lift pump works to build pressure or suction in the gas tank thereby encouraging the fuel level to rise to the injection systems and on to the engine block.
Lift pumps have several applications beyond automobiles and are also used in sewage systems to pump out waste from a full sump pump. A typical rotary injection pump on a Diesel has to not only supply the fuel precisely to the injectors it also has to lift it from the fuel tank through all the filters etc. Wear and Tear eventually means the lift pump inside the injection pump cant do it efficiently anymore and as it slowly loses its ability to suck fuel the main part of the pumps operation suffers with lowering internal pressures resulting in lower fuel delivery and reduced pump.
