Keeps the fuel clean
I ordered filters for my truck 14 days ago, I got the parts yesterday.It’s been about 36 hours since I received my order and the seller is asking me for a review of their products. I have not had time to change oil and filters yet, so I don’t know how the filters from Docs are working. But I know they were much less expensive than going to my local parts store. If you have lots of time to wait for less expensive parts, I’d surely recommend these guys.
fit perfect and took less than 5 minutes to put on. my truck runs a whole lot smoother now
Great purchase! fits perfect as all Docs filters. I can honestly say from New pickups 2023 to 1996 Docs has yet to fail my expectations! 5 stars keep up the great product, customer service & shipping.
Been using it a few weeks now and works as good as a fuel filter should
Worked great. The Napa one did not screw in?
Hello I need help returning this filter and ordering the right one, I need the fuel filter for a late model 1999
Great filter and even greater price
Haven't used them yet but did receive them if they work good will definitely re order again.
Filter worked great! Installed at the beginning of a 7hr road trip. Made the trip with no hesitation. Will be ordering from doc’s for future filters.
