In some cases, when installing aftermarket turbos in your Cummins can quickly become a headache. Especially when you are trying to couple aftmarket parts with factory parts. This Oil Drain Adapter from Fleece Performance at least solves one headache. This adapter is made from high quality 6061 aluminum and anodized black for a superior appearance and includes two o-rings for a proper seal. It fits into the engine block drain tube location just like the factory drain tube and allows you to route your own 7/8" ID hose turbo drain line.
