Good oem filters
Same as the OEM filters that come in my AD 100 GPH, will have to crimp the line from the tank to stop flow when changing them, I have a sump so that may be the reason I had to.

Great prices. Quicker delivery than anywhere else.
I use these on my 03 Dodge Ram 5.9 diesel Cummins motor. It filters out the smallest dirt particles which destroy your fuel injectors, fuel rail and pistons. Much higher quality than original manufactured fuel filters.

Stop putting it off and do it
No issues like other reviews? Came in a box wrapped in brown paper and then in a bag with each sealed in plastic individually. No visual defects. Will update if it seals properly. It sealed properly. Primed great clearly lol. No issues at all. 1-13-2026. If any issues with filters then self rise this will be updated.

NO RESPONSE ABOUT RECEIVING ONE FILTER THAT WAS DENTED
BOTH WATER SEPARATOR FILTERS WERE OK. ONE OF THE DIESEL FILTERS HAS A FAIRLY LARGE DENT. NO DAMAGE TO THE BOX. MY PRIOR ORDER ABOUT ONE YEAR AGO WAS FINE.
