4944404 Cummins Fuel Cooler

Offered is a drop-in replacement for the 4944404 Cummins Fuel Cooler. There are 2 configurations.  One is stainless steel and the other is a standard copper configuration.  The part we sell is the copper configuration. It will work for both OEM configurations and we have enough coolers to know our configuration is quite durable. 

This cooler has a 1 7/8" seawater connection and seal-lok fittings for the fuel connections. We ship this cooler with 3 o-rings.  You only need 2 but we send you one extra just in case one gets damaged or misplaced.

A 2-year pleasure warranty exists for manufacturing and materials issues and it is made with OEM equivalent materials. We guarantee all of our parts for fit and function. Order with confidence.

You will also see a version of the OEM product that is made of stainless in our pictures but the OEMs make a copper version of this part as well.  Our replacement uses a copper shell.  We've had parts in the field for some time now and have witnessed no issues with longevity.   Feel comfortable using this as a replacement for either version.   This cooler has a 1 7/8" seawater connection and seal-lok fittings for the fuel connections.  This unit has been tested in the field under rigorous load conditions and has performed well over time.   We've made a strong effort to make this equivalent in all areas.

Similar products:

There is a larger fuel cooler used by Cummins and Caterpillar but it is made differently so they are not equivalents to each other in fuel cooling.   

Both coolers can be used on the QSB and QSC so make sure you consider the dimensional diagrams when determining which part to order. 

The two parts are not interchangeable. 

The larger Fuel Cooler is the 5291460.
