The CAT 1R-0750 Fuel Filter is an advanced efficiency fuel filter designed to remove small contaminants that can potentially cause the most harm. Any filter can remove some abrasive particles, but where many competitive filters fail is the ability of capturing and retaining those particles which are most damaging to sensitive fuel system components. 

With a strong one-piece can design and non-metallic center tube, CAT Fuel Filters maximize cleanliness, improve performance, and protect vital components. This leads to longer life and higher resale value! If your GM Duramax, 5.9L or 6.7L Cummins is equipped with an XDP CAT Filter Adapter, this is the filter you need to service it.

Great Filter, Much Better Than Stock

The CAT filter is a must have. Filters much better than stock. Gives me peace of mind knowing I have that kind of my protection for my injectors specifically. Definitely recommend this to anyone with a diesel.

Most Popular Questions

What do I do with water sensor that screws into stock filter if I use conversion?
View Staff Answer 
The Water in Filter (WIF) sensor at the bottom of your factory filter is disconnected. This sensor can be saved or discarded as it will not be re-installed. (Removal of the WIF sensor will not trigger a check engine light.

The Cat 1R-0750 is one the best alternatives to running a factory filter. The XDP Cat Filter Adapter is required to run these filters though. The XD171 adapter kit can be found by clicking HERE. It even includes a filter!
