What is a big line kit and do I need this for my install? If you are driving a 1998.5-2007 5.9L, 2007.5-2009 6.7L, or 2010-2017 6.7L Dodge Ram Cummins then you may want to install this kit to get the most accurate readings on your Fuel Pressure Gauge. A Big Line Kit replaces the factory restrictive line from the fuel filter housing to the injection pump and allows your Dodge’s fuel system to supply more fuel to the injection pump. A big line kit replaces the narrow OEM fuel line with a larger diameter fuel line that allows for a better flow of fuel.
For 98-07 5.9L and 07-09 6.7L Dodge Ram drivers a Big Line Kit is not required for installing a fuel pressure gauge. These Dodge Ram drivers can choose between installing a banjo bolt or a Big Line Kit to receive the most accurate readings from their fuel pressure gauge. A banjo bolt adapter will replace the stock banjo bolt on your Dodge and provide access to the injection pump for those accurate readings directly from the source. Whether you choose a Banjo Bolt or the Big Line Kit for your 98-07 or 07-09 Dodge Ram, GlowShift has you covered as we offer both thread adapters of your choice. As for the 2010-2015 6.7L Dodge Ram Cummins drivers, a banjo bolt is not available for your truck and the best option to properly monitor your fuel pressure readings is to invest in a Big Line Kit.
Maybe you are running an aftermarket lift pump in your Cummins and are not sure if a Big Line Kit is for you. In this case, you will not have to purchase a banjo bolt or Big Line Kit. Either install the Fuel Pressure Sensor directly into your lift pump sensor port or buy an inline T-Fitting adapter to install your Fuel Pressure Sensor in line to get a Fuel Pressure reading.
GlowShift includes all necessary parts to complete the installation, as well as instructions for a successful install.
