I have the EFH™–DM1R0750 adapter on my 2018 2500HD GMC Sierra. For over 8,000 miles I have had zero issues. Installation was 20 minutes and easier than I expected. No leaks and the money I’ll save on replacement filters will pay off quickly. Well worth the time/money and filter changes will now take a couple of minutes. Plus, the Cat 1R-0750 filter is top notch.
