What is a Big Line Kit and why do I need this for my install?

If you’re driving a 2017-2020 Ford Super Duty 6.7 Powerstroke, 1998.5-2007 Dodge Ram 5.9 Cummins, 2007.5-2009 Dodge Ram 6.7 Cummins, or a 2010-2017 Dodge Ram 6.7 Cummins, we have truck-specific Fuel Pressure Big Line Kits in stock. You can install this fuel pressure adapter to get extremely accurate readings on your Fuel Pressure Gauge.

Big Line Kits replace the factory restrictive line from the fuel filter housing to the injection pump and allow a diesel truck’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.

Whether you need a Dodge Ram Fuel Pressure Big Line Kit or Ford 6.7 Powerstroke Big Line Kit, each set comes with Rubber Fuel Hose, a T-fitting, Brass Push-On Hose Connectors, Hose Clamps and more. But allowing the fuel system to flow more freely you’ll gain access to better fuel pressure readings.

Add a 6.7L Powerstroke Big Line Kit, 12 Valve P-Pump Big Line Kit, 5.9L Cummins Big Line Kit, or a 6.7L Cummins Big Line Kit depending on your make and model. These fuel pressure adapters go hand-in-hand with installation of an aftermarket fuel pressure gauge that keeps you alerted to any unusual dips or spikes in the fuel system.

GlowShift includes all necessary parts to complete the installation for each Dodge Ram Cummins Big Line Kit or Ford Powerstroke Big Line Kit, as well as instructions for a successful install.
