Hello,

I have a 2001 Ranger 2.3 liter 5 speed. 173k miles
How do I depressurize the fuel system? There is a hose coming from top of engine going to a round device with a 2" **** on it. On the side of this device is a small "bike tire" air stem.
Is this bike tire stem how I would depressurize prior to changing fuel filter?I want to avoid fuel spray.

Thanks

 

Start truck.
Pull cable on Inertia switch for fuel pump.
When truck dies, fuel system is depressurized...
Turn ignition off and plug the cable back into the Inertia switch.

There is still some pressure in the fuel line so wear goggles and wrap fuel line with cloth when opening to replace filter.
