Can you have too big of a lift pump?
Can you have too big of a lift pump?
No it will not hurt the pump. But it could cause you headaches down the road. Running way too much fuel to an injection pump that can’t handle it can cause an increase in fuel pressure, which on some trucks could cause damage to that injection pump and possibly cause it to fail.
What’s the difference between fuel lift pump and high pressure pump?
Modern fuel pumps allow automobiles to operate at higher speeds and improve fuel economy in cooperation with a fuel injection system. Lift pumps add to that system by helping raise the level of fuel into the engine block by creating suction and managing air flow.
Can you over size a fuel pump?
To answer your question, yes you can go to big with fuel pump. An oversized fuel pump can be bad if you don’t have the proper components to call for it.
Can a lift pump be used as a pre pump?
This low pressure, high flow submersible lift pump is mounted inside the main fuel tank and can either feed fuel to a surge tank or an external high pressure fuel pump directly. It will not handle being run under any significant pressure, but for its intended application as a lift or pre pump it is ideal for many applications.
What kind of pressure does a lift pump need?
The job of a lift pump is to supply low pressure fuel (from the tank) to the injection pump on the engine. Most lift pumps, aftermarket or OEM, provide between 8-to-15 psi worth of supply pressure (aside from the 7.3L, 6.0L and 6.7L Power Stroke engines, which call for 45-to-65 psi).
Where is the lift pump on a VDO?
Furthermore, when using an external surge tank, a low pressure lift pump is essential to fill the surge tank. This low pressure, high flow submersible lift pump is mounted inside the main fuel tank and can either feed fuel to a surge tank or an external high pressure fuel pump directly.
Do you need a suction tube for a lift pump?
For most fuel system installs, dropping the tank is a requirement for an aftermarket lift pump system install. This is especially true for fuel systems that employ what’s known as a draw straw, or suction tube (pictured), which is what the lift pump pulls fuel through.

What is the lift pump and filtration system?
The AirDog is a lift pump and filtration system, that enhances the fuel delivery to your engine with a commercial duty system. Your high performance diesel engine demands higher fuel flows. Yet higher fuel flows increase the vacuum at the fuel pump and agitation in the fuel tank.
What does a lift pump do on a diesel truck?
In this day and age, it’s actually rare to peer under a diesel powered pickup and not see an aftermarket lift pump system bolted to the frame rail. The job of a lift pump is to supply low pressure fuel (from the tank) to the injection pump on the engine.
