Show original supplier description
The Modern Muscle Xtreme single pump fuel system is an upgraded drop-in fuel pump module engineered for 2011-2023 5.7L and 6.4L HEMI Jeep Grand Cherokees and Durangos. This system is designed as a direct replacement and offers a plug-and-play installation. It is recommended for vehicles that have undergone significant modifications, such as the installation of a new camshaft, ported heads, or a supercharger, to ensure adequate fuel delivery. This fuel system is suitable for naturally aspirated applications looking to utilize E85 fuel. For boosted applications, it is rated for builds up to 750HP when using 93 octane pump gas. The system has dimensions of 8x8x14 inches and weighs 3.00 lbs. Installation instructions and operation manuals are available for download, and buyers are advised to check local and state laws for emissions compliance before purchasing.
