That is a handy link...thanks! I'm still courious about the tube that comes out of my fender, turns in front of the battery, and goes into the front wall. Do most people leave those in? I know truck a few years before mine had a plastic tube in between the two walls of the fender that they remove, but as I under stand it GM took those out on before they built my '94. Just looking for ideas; this is interesting to me.
