{"product_id":"ii-4g-df-165-165-gph-fuel-air-separation-system","title":"II-4G DF-165 165 GPH Fuel Air Separation System","description":"The AirDog II-4G DF-165 is a diesel lift pump and fuel air separation system engineered for 2011-2014 Chevy\/GMC Duramax 6.6L Diesel engines. The suction side connects to the factory suction fitting in the fuel module, while the pressure side interfaces directly with the factory injection pump feed line on the frame.\n\nAir and vapor are returned to the fuel tank through a supplied filler neck tee. This particular kit is a 165 GPH (Gallon Per Hour) lift pump system, recommended for moderately modified trucks. The AirDog II-4G DF-165 is specified to support 500HP-800HP and operates at a preset pressure of 8 PSI, contributing to improved throttle response, a smoother idle, and enhanced acceleration.\n\nInstallation is described as one of the easier setups, particularly for Duramax trucks which often lack a factory lift pump, leading to significant performance gains. The system's design helps to remove air and water from the diesel fuel, ensuring cleaner fuel delivery to the injectors and potentially extending the life of the injection pump.","brand":"AirDog","offers":[{"title":"Default Title","offer_id":52686830502200,"sku":"A6SABC410","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660180228.jpg?v=1784877225","url":"https:\/\/store.motormia.co\/products\/ii-4g-df-165-165-gph-fuel-air-separation-system","provider":"MOTORMIA","version":"1.0","type":"link"}
