Coolant plug to eliminate the coolant riser tube coming off of the oil cooler on your LBZ or LMM Duramax. This allows you to eliminate the coolant tube to make more room under the hood or just simply clean up under the hood! This is needed in most applications when using S300 or S400 turbos or when doing a compound turbo setup. Includes high temp silicone o-ring for a long-lasting leak-free seal.
Our Billet Aluminum Bottom Sump with Integrated Fuel Return System completely eliminates the need to run the return of your aftermarket fuel pump to the top of the tank or cut into the fuel filler neck, therefore cutting install time tremendously!
