Get the most out of your machine and improve your bottom line with maximum filtration efficiency and protection.

This fuel filter 1R0750 is specifically designed to capture the smaller particles that do the most damage to fuel injectors, fuel pumps, and other engine parts.

Fuel can become contaminated at many places: directly from the distributor, during operation, or through maintenance work.

Without a proper fuel filter, your engine can become clogged with unwanted debris, such as dust and rust. The result is restricted fuel flow and diminished performance as your engine struggles to draw ample fuel to continue operating.

The Caterpillar 1R-0750 Fuel Filter filters provide the superior quality and protection you need to maximize your engine's life.

Authentic Caterpillar 1R-0750 fuel filter made in the USA. Don't settle for any other brand! Cellulose media filters particles as small as 2 microns. This filter is commonly used for Duramax diesel fuel filter adapters and conversions.

 1. Is this filter rated for suction?

This is a cat fuel filter on the return side. This is not a suction filter

2. What is the size of the gasket like diameter?
2.8 inches

3. Is CAT 1R-0750 a diesel filter or a hydraulic fluid filter? Also, is this equivalent and interchangeable with cat part# 1p-2299?
It is a diesel fuel filter. A CAT 1R-0750 is a 2-micron filter, while a CAT 1P-2299 is a 6 micron.

4. What is the difference between this 1R-0750 vs 1R-0751?
The 1R0750 has a 1-inch thread port. The 1R0751 has a 7/8 inch thread port.

5. This filter still separates water correct?
Yes just doesn't have a drain on it. I use it in conjunction with an air dog system that has a water fuel separator and emulsification filter and it filters down to two microns.

Works beautifully.

I modified my Jeg's 40 gallon parts washer to include a Carter automotive fuel pump because I am using the PSC 1000 solvent sold by Tractor Supply. Naturally I needed a quality fuel filter that would meets the needs of my build. After studying the topic and considering the alternatives I chose the Caterpillar 1R-0750 for its filtering ability and reputation and have been very pleased with my choice. To match my color scheme I sanded the filter, primed, painted, and clear coated the filter black. It looks great and works great. Who could want more?

Caterpillar products have performed very well for my boat and truck. These filters have been installed on every diesel motor vehicle we have and no issues.
