Great OE filter
Purchased this to do a annual service on my Cummins ISL9 on my 2017 Tiffin. Great price and easy to install. Saved a ton of money doing it myself.

Great quality filter
Can’t go wrong with Fleetguard filters. I use them on all my diesel trucks and Class A camper and they work great. Nice purchase

Water fuel, separator filter
I bought this filter for my motorhome. They were good quality and cheaper, and what you could buy them at the parts store would buy them again.
