Big Line Kits

GlowShift’s Big Line Kits upgrade and expand your diesel truck’s restrictive fuel pressure line, enabling you to easily install a fuel pressure sensor for extremely accurate readings. By gaining access to the injection pump inlet and replacing the restrictive line from the fuel filter housing to the injection pump inlet, you’ll give your vehicle’s fuel system the chance to flow properly. Each kit is designed for a specific make and model and all parts required for installation are included.
