1992 Park Avenue base: various tuneup questions

[TheRedSharon]

Hello folks. Today I decided to give the old girl some love and change the oil, spark plugs, fuel filter, and air filter. I've been searching for almost an hour now, but I can't find three things:
1) Spark plug gap setting for the 1992 3800 base
2) Spark plug torque
3) Fuel filter replacement procedure.
If I do happen to run across these things, I'll post my findings here for the next confused person.

1) Spark plug gap setting for the 1992 3800 base

Gap @ .060

2) Spark plug torque

14mm Taper Seat 7-15 ft. lb.
Installation Guide

3) Fuel filter replacement procedure.

IIRC, the '92 has has quick disconnects at both ends. Relieve the fuel pressure by removing the gas cap, unplug the connects while holding a small can or cup to catch residual fuel, then remove the 1 mounting bolt. Put the new filter into the mounting bracket (be sure it faces the right way) and bolt bracket back into place, then push the line connectors onto the new filter. Don't forget to put the gas cap back on!
