Look on the passenger side frame rail. Pull the fuel pump fuse, then start engine and let it run until it dies. That will eliminate most of the fuel in the line under pressure.

Also, unhook the battery for safety's sake. It's real easy to introduce a spark under there while working with tools due to the relatively close location of the starter solenoid, knock sensor heat shields and other components.

Thanks Julian.
Have changed filters on many different vehicles, so know the safety routine.
It is always great to get the location of the filter before putting it up on stands. Never fails, that if you raise the left front, the filter will be in the right rear. Get my drift?
Again thanks, now I have some filter changing to do.

Loosen the gas cap also to relieve pressure. Easiest way to reach the filter is to pull the engine!!! Not really it is just hard to get wrenches on it. Donf

I got so frustrated trying to change mine, I took it down to my friend's shop and had them remove it. Having a lift makes it that much easier to change (but not by much)!

the bottom connection on my 92 was relatively easy, but until I asked for help on the Forum, I could not get tl the top connection.

they said to lift the hood and disconnect the clamps holding the fuel lines to the firewall or fender well (can't remember exactly). then pull it up. worked like a charm.

Good luck
