I am going to do the spark plugs and fuel filter this weekend, and I had a few quick qestions...
What should I gap the plugs at? (Standard Champion copper plus)
Also, what is the procedure for doing the fuel fliter as I have never done this before?
Any tips or tricks to either of these projects would be most appreciated! |

Spark plug gap for the 4.0 is .038. I do not know if that is different for the 3.9 or not, since yours is a 95. |

Kyle:
Make sure you are in the right state of mind for the fuel filter swap!
The bump fittings are almost guaranteed to be seized. If you break one loose from the filter canister, you probably won't be able to break the fitting nut loose from the metal tubing. What then ends up happening is that the rubber tubing begins to turn and when you pull the wrench off, it will recoil and tighten back up on you. After you have fought with this for awhile (my brother in law says it works better if you swear at it in Serbian and call RN and AB to whine about the injustice), you might just be able to get one end off, but you won't be able to put it back together as the metal tubing and the fitting nuts won't cooperate.
Sounds pretty bad, doesn't it? Well, there is a solution. Using your handy dandy tubing cutter, cut the metal tubing as close to the crimped fitting as you can on both ends of the filter-not right next to the filter, but where it initially goes from steel to rubber. Now, you have the filter in your hand with little pieces of tubing and fittings attached. Carefully remove the fittings from the filter-they will unscrew much more easily now that there is no tension on them. On the other end of the bump fitting, there is a crimped fitting. If you very carefully cut the outer metal crimped part off and remove the tubing, you'll find that there is a cool hose barb beneath. Screw the bump fitting back into the fuel filter and use the hose barb on the ether end as you would any hose barb-buy some fuel line and hose clamps and bolt back together and Rover on!
I've been told that there is a retrofit kit that Rover sells that essentially does the same, but I got creative with my brother in law's rangie and came out OK.
As for plugs, the 3.9 gaps at 0.032-0.038 ~0.035.

Damn Paul, are you serious? I might have to put off the fuel filter change until I am emotionally prepared, lol. |

I believe the 3.9 is .033, and the Bosch I bought were pregapped to .032
I have a 95 disco, and the Fuel filter looked like it had never been replaced.. the most disgusting crud came out of it. I had no problem removing it though, just make sure you know which way you're turning ;) |

It's a lot easier to remove the Fuel filter with the tire off, but I did it without removing the tire. It just took a tad bit more patience. The fuel filter removal is pretty easy, just grab 2 wrenches. You need to hold one of the nuts, while you loosen the other.
The nuts should break free, and slide down the fuel line, out of the way; and you just have to kinda tilt the fuel filter over, down, and out. It should come out with some ease.
Expect a little bit of fuel to come out, as well, so keep your eyes clear of the filter. |

Wow guys...thanks! This board never ceases to amaze me and after reading what Paul had to say, I may wait until AFTER the job is done before I dip into the Sam Adams cooler. Thanks again,

You got lucky! I live in Indiana, where those cad/zinc plated steel nuts don't last long after they start salting the roads.
