Review on TP1015 Fuel Filter: Perfect Fit for 6.6L Duramax Diesel in Chevrolet Silverado 2500HD/3500HD & GMC Sierra 2500HD/3500HD 2017-2019/Chevrolet Cruze 2014-2019, Replace 23304096 by John Jones

Buy the original AC Delco TP1015 and you won't be disappointed. The filter media was nowhere near AC Delco in thickness or quality, so it's cheap. Try looking for the certifications listed there that relate to actual filter performance, not environmentally friendly manufacturing processes. Need to take a closer look at the SAE USA standards, which list them as the 1839 Standard Society of Automobile Engines? no typo. Frustrated by the sheer volume of Chinese junk they advertise their engineers as internet sales professionals. I believe that. Filter weight significantly lower than OEM = less material. I'm glad I only bought 2. I will not use them on my Duramax, not worth the risk.
