The Full Send Diesel FSD-18-B replaces the factory heater hoses and hard lines on 1989-1998 Dodge trucks with the 5.9L 12 valve Cummins using black braided hose and billet AN fittings.

The kit bypasses the heat exchanger on the side of the block. That cooler is known to fail and mix coolant with transmission fluid, so removing it from the heater circuit eliminates the risk.

• Braided Hose: Black braided AN lines.
• Billet AN Fittings: For a leak free system.
• Heat Exchanger Bypass: Removes a known failure point.
• Complete Kit: All hose and fittings included.
• Lifetime Warranty: Full Send workmanship warranty.
