Doc's Diesel 6.6L Duramax Filter Set — Fuel & Oil Filters for 2001-2016 Chevy/GMC (Replaces TP3012)

Doc's Diesel two-piece service kit replaces TP3012 and delivers matched fuel and oil filtration built specifically for 2001–2016 6.6L Chevrolet and GMC Duramax engines.

This filter set packages a high-efficiency fuel filter (DPS9059) and a premium oil filter (D5399) so you can perform a coordinated service without hunting for separate parts. Both elements were tested to specific particle-capture levels and engineered to meet the fit and flow characteristics required by 6.6L Duramax installations. The kit is intended as a direct-replacement service pair for owners who want reliable filtration that aligns with factory mounting and service intervals.

How does this set fit my 2001–2016 6.6L Chevy or GMC?

The kit is built for the 6.6L Duramax family produced between model years 2001 and 2016, designed to match OEM filter housings and threads so the parts install without modification. Verify your year and engine configuration using the fitment tool on the product page before ordering to ensure compatibility.

• Direct-fit replacements for common 6.6L Duramax filter locations
• Thread, gasket, and sealing dimensions engineered to OEM tolerances
• Includes both fuel and oil filter elements for one complete service

What filtration performance can I expect from each component?

Independent testing reports the fuel filter delivering high micron efficiency for contaminant removal, while the oil element is rated to capture much smaller particulates to protect engine internals. These performance figures represent lab-tested capture rates and help reduce wear from abrasive particles when replaced at recommended intervals.

• Fuel element rated for high-efficiency particle capture down to small micron sizes
• Oil element rated to retain fine contaminants commonly found in diesel engines
• Both parts tested individually to verify consistent filtration performance

How often should I replace these filters during maintenance?

Service frequency depends on your vehicle use and manufacturer guidelines; fuel filters are commonly replaced more often under heavy duty or contaminated-fuel conditions. Follow your truck’s warranty and maintenance schedule, and consider more frequent fuel filter changes if you operate in dusty environments or use off-road fuel sources.

• Follow vehicle manufacturer intervals for warranty compliance
• Typical fuel filter refresh: every 5,000–10,000 miles, up to 15,000 in light conditions
• Oil filter changed every oil-service interval per your truck’s maintenance plan

What comes in the box and why buy the matched set?

The package contains the DPS9059 fuel filter and the D5399 oil filter, both selected for the same Duramax application so one purchase covers the most common routine service needs. Buying the matched set simplifies maintenance planning and ensures replacement parts are compatible with one another and the vehicle’s filter mounting systems.

• Included: one DPS9059 fuel filter and one D5399 oil filter
• Pre-tested combination reduces guesswork and streamlines a single service visit
• Eliminates the need to source separate filters that may vary in fit or performance

Who is this for? This Doc's Diesel filter set is aimed at Duramax owners, independent mechanics, and fleet managers who service 2001–2016 6.6L Chevrolet and GMC trucks and want a coordinated fuel-and-oil replacement option. Choose this kit when you need OE-style fitment, lab-verified filtration efficiency, and a straightforward two-part service solution that keeps your maintenance efficient and predictable.
