They say any particles larger than 4 microns can plug your injectors, an expensive pain to replace even if you do it yourself, do this job once and you’ll stop at nothing to ever risk having to do it again. The $99 OEM AC Delco filter GM recommends only filters to 12 microns, obviously they like selling you injectors and service, this filter is rated down to 2 microns, they don’t sell injectors or service so they only have to focus on selling you the best filter they can make. Here’s the downsides... You’ll need to first buy the adapter kit to use this, adapter not included, this is just the replacement filter for those of us who already have the adapter. The good news is the adapter kit is simple to install, just screws on like a filter, this screws onto the adapter. You’ll spend less for this filter and the reusable adapter than you’ll spend for just one OEM filter at the GM parts counter. You’ll then be able to buy 4 of these filters for what you’ll pay for just one of the OEM ones, and the CAT is a much better filter. The other downside, if you replace your OEM filter with this one you’ll no longer have a water separator since that’s part of the OEM filter. You just leave the wires for the water in fuel sensor unplugged. The downside is you’ll want a water separator in your diesel fuel system and will have to get one. Most of us just install “lift pumps” that also have their own fuel filters and much better water separator system built into them. This is the idea way to go, you’ll have redundant fuel filters, a separate (more effective) water separator and your fuel system will then be pushed (pressurized) into the injector pump instead of being sucked (vacuum). The plus in that is if you get a fuel leak in a line it will spray out and be easy to find, where as with the suction system it will just suck air into your fuel system causing poor performance, expensive damage, and a lot of difficulty in finding the source of the leak. I personally like the AirDog II 165GPM system regulated to push my fuel at about 12psi. I run a fuel low pressure gauge before my injector pump and a fuel high pressure gauge after it on my fuel rail. Monitoring the pressure lets me know when I need to change my fuel filter. These CAT filters last me a year before I change them even if I’m not seeing any pressure drops on my gauges, your own mileage will vary depending on the fuel quality you buy. The entire system, CAT filter with adapter, Glow Shift high and low fuel pressure gauge (optional) and AirDog lift pump system still costs less than what you’ll pay just in parts for a single CP3 injector pump or new injectors. You can also install it all very easily and quickly yourself, new injector pump or injectors not so easy, in fact their a pain to install and anything but a quick job to do. Review: Well worth it - I bought these in place of my ac delco fuel filter on my Duramax, you do have to get the adapter kit but it's well worth it, it's cost effective, good filtration compared to stock, seals good and easy install, i remove my fender liner for easier removal and install, highly recommend ## Features - Genuine CAT 1R0750 filter - Quantity of 1 - Thread size (inch): 1-14-2B - Height: 181.5mm - Diameter: 85.7mm - Advanced efficiency 2 micron absolute cellulose media filter.

The threads on both these Cat filters are 1'-14. **Q: Does this come with the two o rings?** A: No. I only saw one o ring rubber gasket glued onto the filter. **Q: How many miles can i get on my 2002 duramax lb7 before changing the cat 1r-0750 fuel filter?** A: Most web diesel formums advise 20 K miles. Since injectors on an lb duramax are a problem I change mine every year or 10K miles. **Q: Is this filter rated for suction?** A: This is a cat fuel filter on the return side. This is not a suction filter ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Filter, you probably need the adapter kit to use it *by R***R on January 19, 2021* I use one of these in place of the stock GM fuel/filter on my LLY Duramax.
