Relive Fuel Pressure
Need to change out the fuel fitler in my 89 Cherokee 4.0. I've heard I need
to relieve fuel pressure before disconnecting the filter. I don't like the taste of gas. How do I relieve pressure? Do I need to? How do I restore fuel pressure? Thanks Carl |

There's a Shraeder valve (like a big tire stem valve) on the fuel rail
between the injectors. Unscrew the plastic cap covering the valve and after placing a rag underneath to catch the fuel, depress the little pin to relieve the fuel pressure.

Thanks, Jerry. Can I assume it will re-build pressure on it's own with a bit
of extra cranking? Carl "Jerry Bransford" > wrote in message news:hldTd.21770$Tt.9403@fed1read05... > There's a Shraeder valve (like a big tire stem valve) on the fuel rail > between the injectors.

Yep, no problem... all automatically.

You can remove the fuel supply line from the fuel rail. Fuel will spray, so
cover the connection with a rag. The obvious admonitions of closed areas and smoking should be observed.

In the event it does not rebuild the pressure, you can disconnect the fuel
supply at the fuel rail, direct the hose into a container, and cycle the key a few times until fuel comes out of the hose, then connect it back to the rail.

Hi Carl,
Cycle the key on and off many times as it only pumps for about three seconds and shuts off without the engine running to save us in an accident.
