Which And Where To Buy A Fuel Pressure Gauge

Owning a fuel pressure gauge is now becoming a must. All vehicles now use an electrical fuel pump to deliver fuel (under high pressure) to the fuel injectors and the best way to diagnose this fuel pump is with a fuel pressure gauge.

As mentioned earlier (in fuel pump test 2), in all of the Ford 4.0L V6 equipped vehicles... Ford was kind enough to put a Schrader valve on the fuel injector rail where you can tap into the fuel system and check its performance.

A fuel pressure gauge can cost you as little as $40 (US) or as much as $200 (US). The price difference depends on what type of fuel pressure gauge set you buy, this means either buying a Non-Professional Technician grade tool or a professional technician grade too. Whichever one you buy, it's an investment that will pay for itself many times over.

Your local parts house will have a fuel pressure gauge set to sell you, although you'll pay more for it and it won't be a professional grade tool (if that's what you're looking for).

Not sure if the above fuel pumps fit your particular 4.0L Ford? Don't worry, once you get to the web-site they'll make sure it fits (by asking you for the specifics of your vehicle). If it doesn't fit, they'll find you the right one.
