Doc's Diesel Filters are spec'd and designed to meet or exceed the quality/performance of the original filters (OEM's) that come in your vehicle. Doc's premium grade media filter paper used on all Doc's Filters is what sets Doc's above the rest.
We wanted to go one step further in customer trust by providing,SAE J1985 3rd Party Testing of our parts.We did a full upstream and downstream efficiency testing along with a single pass efficiency test method. Our main fuel filters have been 3rd party tested, and as we get more testing we will be reporting the results.
The shipping was fast and as promised. The parts are as good if not better than OE and I saved some cash.

I do not know if it was the gasket or filter but I had a fuel system failure (loss of pressure) about 300 mi after the filter exchange. The problem was coming from the filter for the water separator. I removed and inspected the filter and gasket twice. There appeared to be no physical damage to either but the truck would not build up any fuel pressure. Broke down twice, on my way to work, two days in a row. Luckily, I still had the old filter and gasket. Put them both back on and the truck has been running fine. Now, I have to go get another fuel filter. Should have just gone to the dealer, in the first place...
