Anyone know where the fuel filter is on a 1998 Expedition, 5.4 L engine?

 

Driver's side, on top of the frame rail between the doors.

 

AND you need a special tool that you can buy at the parts store. It is made for removing those special circular connectors that Ford uses. It's about 20 bucks or so.

 

OOOPS ! I forgot about the tool...........Thansk dude.

 

How is the gasline pressure relieved??

 

There's a specified procedure (don't remember off the top of my head) but I didn't follow it when changing mine. Very little gas seeped out and the pressure was not much at all. Just in case I had a big towel wedged between me and the lines/filter. I wouldn't recommend smoking while doing the swap though.

 

Just did it. It took about 15-20 min. Very little trickle as Buzzard mentioned. No big deal. The removal tool is a must though!!

 

I paid 5 bucks for my tool

 

There is a pressure relief valve on the fuel rail over the intake manifold, passenger side. It has a black cap on it. It's a tire valve, hehe.

 

There is a simpler method for relieving fuel pressure. It is either in the owner's manual or in on of the aftermarket manuals I have. 1. Find the fuel pump reset switch.
2. Turn off the fuel pump.
3. Crank the engine. It won't start.
4. Fuel pressure will be gone.

 

If you can't find the switch, pull the fuse from the underhood fuse box. I prefer starting the motor, then pulling the fuse while idiling. This way, after the power is cut to the fuel pump, the motor will suck out some of the residual gas in the line.

 

Is that really a good idea? What affect does this have on the engine (besides the obvious)?
