The aFe Pro GUARD D2 is a replacement fuel filter element for the 2011-2016 6.7L Power Stroke in F-250 and F-350 Super Duty trucks. It is a direct OE-style replacement that drops into the factory canister, so the job is an element swap rather than a fuel system modification. The Pro GUARD D2 line is aimed at heavy-duty diesel service, where aFe says it delivers increased flow and efficiency along with maximum filtration and minimal flow restriction. Compared with a basic stock-style filter, that matters for protecting the high-pressure fuel system, injectors, and fuel pump on a 6.7L Power Stroke. Searches like "6.7 Powerstroke fuel filter upgrade," "F-350 6.7 diesel fuel filter element," and "Pro GUARD D2 fuel filter 2011-2016" will match this part.
Because the element mounts in the chassis-side canister below the driver's door along the frame rail, most owners can handle the swap at home with basic hand tools. The element includes the canister O-ring seal, so the old seal should be removed and the new one checked before reassembly. Confirm the year range against the manufacturer's application list before ordering, since listings vary on whether 2017 trucks are covered.
No. This is the replacement filter element only. It includes the O-ring seal for the canister, and it is designed to fit the factory canister rather than replace it.
It is listed for the 2011-2016 6.7L Power Stroke in F-250 and F-350 Super Duty trucks. Some listings show coverage through 2017, and details vary, so confirm your year and model with the manufacturer before ordering.
The element sits in the chassis-mounted canister below the driver's door along the frame rail, so access is straightforward and the engine-side components are not involved. Because the element is designed to work with the factory canister, you do not need to modify the housing. Replace the O-ring with the one included, make sure it seats fully, and confirm the canister is closed securely before starting the engine. Install time and tool requirements were not confirmed against the manufacturer's install sheet, so check the official instructions for any torque values or priming steps.
