How to Check a Fuel Pressure on a Jeep Wrangler – Low fuel pressure in a car, truck or SUV can be caused by a number of reasons. Leaking or clogged fuel lines, a malfunctioning fuel pump or a clogged fuel filter can all cause a loss of pressure. Fuel pressure is especially important in off-road vehicles such as the Jeep Wrangler, where operating on rough roads and at odd angles forces the fuel system to work much harder.
Tools Used: Tools, Wrench set, Fuel pressure gauge, Fuel line t-fitting, Rubber fuel line, Wheel chocks or wooden blocks
