Got the water separator number....it's Fleetguard FS19594.

As to where to purchase the CAT UHE filter online......probably easier to go to shop or dealer who sells CAT filters.....think my FF here locally was only $17.

 

I ordered 3 1R 0750 Cat for 20.00 each free shipping from alligator performance not bad not great for price but to save the 9.00 dollars I would have to drive 60 miles round trip. Even trying to save 15.00 not worth it.

 

The Fleet Guard filters require the gasket around the threaded port.
The Cat 1r0750 does not. It wont even fit if its on there.

 

I have been using the CAT 1R 0749 which is a longer version of the 0750. About 120,000 miles so far and on stock injectors no issues with that filtration which is good by me...

 

the cat 1R0749 with the fleetguard fs 1000 is what I use on my filter. here is a pix of the wix sub

 

I have an under the intake fuel filter system and I run the Cat 1R-0749 filter. It's long, but fits under there with no problems. This is the same filter used on the big 18 wheeler trucks! I feel more comfortable with the quality of the cat filters.

 

I run the 1r 0750 for 20k miles or more the 1r 0749 what are going to 40k to 50k miles???

 

Just checked a local Cat dealer online and price was $14.50.

 

The UHE version is part 364-5287, has the same 7/8-14 threads, seal ID is 62.3mm, OD is 71.3mm, same as the 1R0751. The 1R0751 uses cellulose media, the 364-5287 uses synthetic. The 1R0751 has a capacity of ~45 grams of contaminants, the 364-5287 capacity is 45 grams. Both have a Beta 75 rating (98.7% efficiency) at 4 microns.

Filters today are not rated any lower than 4 microns if they are using the latest multipass test standards. If they are claiming anything smaller, better ask them what rating system they are using as the 2 micron absolute (absolute = Beta 75) came to an end when AC fine test dust ceased to be used in testing back around 1999-2002. Even filters previously rated at 2 microns absolute by the old test dust such as 1R0750 have been rebadged to 4 micron. Bottom line, the filter probably didn't change but the test method did. I just wish the 364-5287 came in a version with 1-14 threads as well.

 

Probably best to use a fuel pressure gauge to monitor the drop in fuel pressure or change at a set number of miles. I have a fuel pressure gauge, but with multiple fuel filters, that still leave me wondering which filter to change. I just change them all at the same time.

Just for grins, I talked with a guy with an 18 wheeler. His truck uses the Cat 1R-0749 fuel filter and the Cat 256-8753 fuel water separator. The maintenance shop changes all the filters at 13,000 miles. The hours between changes would have been useful as he said the truck hardly ever shuts off. When the truck goes in for maintenance, they change everything at one time. The oil,the fuel filters/etc. Then the truck back on the road making money. Anyway, he has over 780,000 miles on this truck.

 

I figure i will just change my 1r 0750 once a year regardless of miles,i put on about 13000 a year----probable do it in the spring at the same time i do the Amsoil by pass filter/and aftermarket tranny filter.Easy to remember when to change it out/for piece of mind.DW

 

You can go 30,000+ miles easily with the 0749 safely with regards to filtration. Just think how much more fuel that semi runs thru at 13k miles... Has to be at least triple our little 5.9's.

 

Ok I can get Donaldson's. P551311 for 12.00 and the Cat 1R 0749 for 17.00 apiece
Which one? Are they Equal quality?
Thanks

 

Yes. And donaldson makes cat filters. I double checked because in my notes I had the p551319, so I wanted to se what the difference is.

When I first added a extra filtration system to my truck, I was undecided between the Donaldson filter and the Caterpillar filter. I did some "boots on the ground research" at the Caterpillar retail office and the motor repair shop. This place is about 15 miles from my home in San Antonio,TX. They probably work on every type of Caterpillar motor made. First, the shop was clean and orderly, looking impressively efficient. The mechanics were well trained and experienced. I was able to see about 20-25 or more trucks in the shop for maintenance or repairs. I was told, Donaldson do not make Caterpillar fuel filters. They sell both the Donaldson and the Caterpillar fuel filters in the motor shop for those who don't want to spend the few buck more. They said the Caterpillar filter's internals are better hands down. They even had cut off of used Caterpillar and Donaldson filters showing the internals. I think the Donaldson looked rusty, while the Caterpillar had plastic looking internals and no rust. Anyway, from my brief look at the internals, the Caterpillar filter looked to be of better material after being used with diesel fuel. There are slightly different numbers between the two filters for filtration, probably caused by the companies own testings. IMO, one can play with the numbers as a selling technique, but not really add the quality internals to make the product last the long haul. We all know what one can do with statistics and numbers. I think the true test of these two brands of filters is how well it filters and not break down while on the truck for 15,000-20,000 miles. You will have to cut the used filters apart and compare the difference. The mechanic in the shop, to a man, said the caterpillar filter was better. Numbers on paper don't tell you what the mechanics find when they fix engines. From my visit at the Caterpillar shop, I rather go with the product the experienced mechanics recommend than go with numbers on paper.


Hey, Maybe someone will cut the two filters apart and post the pictures!
