Using the Pusher Max 3' Driver - side Charge Tube is straightforward. First, make sure your vehicle is a 2011 - 2016 GM with an LML 6.6L Duramax engine. Then, carefully remove the old charge tube from your engine bay. Install the new charge tube, connecting it to the factory turbocharger and the intercooler. Make sure all the connections are tight using the included heavy - duty 4 - ply silicone couplers and full stainless T - bolt clamps. Note that if you want a powder - coated tube, there will be an additional charge. For maintenance, regularly check the clamps to ensure they're tight and the couplers are in good condition. Also, keep an eye out for any signs of rubbing against the driver - side inner fender or other engine bay components, though this product is designed to avoid that. If you have any issues or need it sooner than the typical 2 - 3 week delivery time, contact the supplier to check stock levels.
