Wehrli Custom Fabrication 100279 Cummins 2nd Gen Swap Turbo Oil Feed & Drain Line Kit

The Wehrli Custom Fabrication (WCFab) Cummins 2nd Gen Swap Oil Feed & Drain Line Kit (WCF100279) is a complete turbocharger oil supply and return solution engineered for Cummins-powered trucks running a high mount 2nd Gen turbo swap configuration. Designed specifically for use with S300 or S400 style turbos mounted in the high mount 2nd Gen position, this kit eliminates the guesswork from custom turbo oil plumbing with precision-made, USA-manufactured components.

At the core of this kit are Teflon-lined stainless steel braided lines — a #6 / -6AN feed line and a #10 / -10AN drain line — engineered for reliable, long-term performance in demanding diesel applications. The extended oil drain fitting assembly features a black anodized billet aluminum construction that simplifies installation and future maintenance access. The engine block connection uses a press-fit billet aluminum fitting with a double O-ring seal and wrench flats for a leak-free, secure connection.

Kit Includes:

• Teflon-lined stainless steel braided #6 / -6AN turbocharger oil feed line
• Teflon-lined stainless steel braided #10 / -10AN turbocharger oil drain line
• Black anodized billet aluminum extended oil drain fitting assembly
• Black anodized billet aluminum press-fit engine block connection with double O-ring seal and wrench flats
• All necessary fittings for turbo, oil pan, and engine block connections

Compatible with: S300 and S400 style turbos in the high mount 2nd Gen swap configuration on 1998.5–2007 Dodge/RAM Cummins diesel trucks.

Built in the USA by WCFab, this kit reflects the same high-quality craftsmanship found across the entire WCFab product line — making it an ideal choice for 2nd Gen swap builds, custom turbo upgrades, and performance diesel builds.
