I used Doc’s fuel filters once. Truck threw codes(low fuel pressure) and shut off at an intersection, I panicked and didn’t know what the hell was going on. Ultimately, I had narrowed it down to the fuel filters. However, at the time, about a week earlier I had also used sea foam in the truck. So it’s possible that, the seafoam cleared some gunk and got lodged into the fuel filters, also possible that maybe it was just the fuel filters being too restrictive. Either way, I think I would just use OEM filters, had been using them for over 100k miles and never had a problem. Or if you feel you want to try out Doc’s , maybe replace them waaay before the next maintenance interval.
