Tombstone Diesel Turbo Drain Line Kit w/ AN Fittings + AN Drain Lock (Cummins 1994–2024)
Upgrade your turbo drain system the right way. This kit replaces the factory corrugated drain tube with a leak-resistant, AN-style braided line and is compatible with our AN Drain Lock to positively retain the block fitting under boost or crankcase pressure. Works with single or compound setups and factory VGT or fixed-vane chargers.
Why Replace the Factory Drain?
On 1994–2024 Dodge Ram Cummins trucks, the OEM corrugated drain tube is easily deformed, prone to leaks, and offers no secure retention into the block. Heat, vibration, and boost can cause the drain to back out or weep. Our kit eliminates those weak points with a serviceable high-temp AN braided line, precision fittings, and ready to adapt to the block-secure Tombstone Diesel AN Drain Lock's (Sold Separately).
