If you've recently installed a new camshaft, ported heads, supercharger or any other horsepower increasing mod on your Jeep or Durango, then you need to seriously consider this new Plug and Play pump. Do not starve your HEMI of fuel! This new single pump HEMI fuel system is perfect for pump gas (93 octane) boosted builds under 750HP, as well as naturally aspirated vehicles wanting to run E85!
