I have a preheater on mine. they also have a fuel backcheck for obvious reasons. all davco parts can be bought at any freightliner dealer. they have a great detailed websight, with all the part numbers & illustration of all parts. compared to laying on the ground & changing the other type fitlers, this is a no brainer for me. e-bay had a new one for sale cheap last week.

ebay has a brand new one for 100.00+ 15.00 shipp. just type in davco.

I think that Davco makes and brand labels for the Cummins - Fleetguard Fuelpro. Mine has 120v and coolant preheater.

Sure look the same.
