What does a fuel transfer pump do for my Cummins engine?

The fuel transfer pump draws fuel from the tank and delivers it to the injection pump at the correct pressure. For your Common Rail Cummins, consistent fuel pressure is vital for the injectors to operate efficiently and deliver the right amount of fuel.

Yes, this pump is specifically designed to fit 2003 and 2004 Dodge Ram 2500 and 3500 models that have the Cummins CR ISB engine with a Common Rail fuel system.

Does this fuel pump come with any installation hardware?
