Replacing Glow Plugs on my Caterpillar 303 CR and More

This time around my Dad and I get into the glow plugs. When I bought this machine it had an "extra" glow plug button. This button was directly wired from the battery (without a fuse) to the glow plug power rail. I am guessing that this was done because the old ones were getting weak. We remove all that extra stuff and re-install the old power rail, along with some brand new glow plugs. While we were working on it we discovered a fuel leak and fixed it. We changed the oil and found some broken brackets on the hydraulic cooler. I used the plasma cutter and drill press to fabricate new pieces.
