The Doc's Diesel Fuel Filter DCS8629OE is a perfect fit for my Ford 7.3L Super Duty (F250/F350/F450) 🚙💪. Installation was straightforward, and the quality of the filter is excellent — you can tell it’s built to last. I immediately noticed smoother performance and peace of mind knowing my engine is protected from impurities. The heavy‑duty construction 🛠️ gives confidence for long hauls, and it feels just as good as OEM, if not better. For the price, this filter is a fantastic value. Highly recommend to any Ford Super Duty owner who wants dependable filtration and long‑term engine health 🔧.

It fits, the filter specs are excellent, the top design allows instal and removal with no special tool and the price is good

Works perfectly.

2000 7.3 fit and works great

It bolted right up with no issues and builds about 70psi. I read a few reviews about the cap so when I installed the fuel bowl I used a docs diesel cap. The dd cap blew off after about 40 miles of driving. So idk if it's the cap that's the issue with this bowl or that the bowl is slightly out of spec. I put on a cheap aluminum cap that I had (I got off e bay and modified it with a schrader) that seems to be working fine.

Exactly OEM, Perfect fit 5-minute change. Tried others that said it fit, not 1/2 inch too tall Bypass the junk and buy this for a perfect fit

Not bad for the 7.3. I haven’t had any problems with the fuel filter.

Great product for the price. Nothing but the best for my 7.3

Put it in and it fits, truck runs fine

Matched picture, good quality

fonctionne tres bien

As described

This product is garbage DO NOT BUY. I bought Docs as a spare to carry in the truck BC when the fuel filter fails the truck stalls and you're left stranded at the side of the road. That's what happened. So, When I went to change the current filter (stalled on the side of the road) to Doc's first the supplied gasket did not fit properly it was to big. Don't know if it was a one off factory defect or ???whatever. Second, the filter would not seat properly in the old cap (bc Doc's did not come with a new cap-never buy a replacement wo the cap bc different brands may not crossover like this one did not) or the fuel bowl. I had to take it apart an rig up a solution with Doc's filter & the old cap & gasket all while at the side of the road. It did not work. By happenstance a diesel mechanic stopped to help. He suggested to just leave the filter out & put cap back on to get the truck home. So I did. Eventually, I put the Docs filter inside old cap and used the old gasket until I could order a new replacemt kit. Therein lies the problem. While I was waiting for the new replacement to come the old gasket failed (BC the cap fits so tight that once you take it off the old gasket is compromised & flattened and will not seat or seal properly again). THUS, a small drip leakage under fuel pressure began while driving that eventually turned into a gusher. I barely made it home with a drenched (hot) engine and smoking from fuel all over it. By coincidence my new filter, gasker & CAP arrived the morning before this failure happened later in the day. Enough said. Needless to say this all began bc Doc's gasket did not fit the cap or seat correctly (to big for it) in the bowl ridge of the fuel filter housing to begin with. Although I was reimbursed the purchase price of this failed product the extensive collateral damage & time lost was extreme & obviously not worth a crap quality product purchase. Again, DO NOT BUY THIS PRODUCT. If I could give a negative star factor this aftermarket product would get it.
