i'm going to change my fuel filter in a few minutes. the chiltons manual says to relieve the pressure through the regulator or some other line. i dont have the tools to this. its says that you need a fuel pressure gauge for both procedures. is there a easy way that i can do this and not make a mess and smell like gas for three days? also, i'm going to change the fluid in my tremec tranny. is there a filter that should be changed at the same time or should i just drain and fill? and i'm using gm syncromesh fluid

thanks for the advice
