your fuel filter is OLD, you should probably change it
whoops, just realized admin john got to it first
and as for the box.., i am very curious myself. i was under my truck today and saw the SAME damn box! it has like fuel lines going to it...almost looks like some external fuel pump assy, but its not, obviously, because the 00s have an access hatch to that.
also...no wonder those things handle better, everything is center and balanced in them
and i'm very highly surprised at what low amount of rust you have! jees. why the heck did the 87-99 h-bodies rust so easily? wtf?
and woot, my post count rocks.
