Customer Reviews
When I went to check my Amazon filter for dirt content inside the pleat the filter came apart! Docs are 100% better when it comes to quality. I feel comfortable to run the filter longer than 50% on my filter monitor.
Quality product for a decent price glad to see they have some aftermarket stuff that works well and fits like it’s supposed to definitely recommend
So far, so good with the fuel filter. I even got some sweet decals to plaster around my office. I will be purchasing more parts in the future.
Easy to order, quick to ship, and exactly what I was expecting. Doc’s is the BEST!!!
The filter was a perfect fit and was shipped right away. I'll be using Doc's for all my DIY applications on my truck.
I had an oil change scheduled at the dealership as my first 4 of them were included when I purchased the truck. I asked how much they wanted to do the fuel filter and was quoted $199. I decided to do it myself and within 10 minutes I had my fuel filter changed for about $30. I will be ordering all of my filters and oil through Docs Diesel. Extremely affordable and easy to do!
Ordered this replacement filter. It arrived quickly, installed without issue, and is doing its job. I will continue to buy this filter, and other items from Doc's Diesel.
The dealership was going to charge me $145.00 to install a fuel filter. Your filter cost me $28.00, it took me 10 minutes to install. I will definitely buy all of my filters from Doc's diesel going forward!!!
Good quality, fast shipping
Filter better the factory filters.
Fuel filter is fine. The plastic housing, but the fuel filter goes in. I wished it was metal.
Everything fit as it should and the price was great.

This is my second time ordering fuel filters for three different diesels, 1 jeep, 1 gmc 1500 & 1 f250, there are quick and it fits perfect havnt had any problems. This is were I buy them from for now on.
Easy install. Good weight and heft, suggesting strong filter media. Be sure to get the 36mm socket; the cap is robustly attached which is a good thing.
Easy install for beginners
Stops more trash. I change it every other oil change. Truck runs great on them.
