I installed a mechanical oil pressure gauge on my truck and I didnt tighten down the hose to the block very tight fearing I might crush that little compression cone. Well it held fine for a few mile but when I started the car up when I was about to go home, it came undone and sprayed oil everywhere. I didnt realize what was happening yet because it was dark and I hadnt turned on the lights yet. When I switched the lights on I saw the oil pressure gauge read zero. I had sprayed out about 4.5 quarts in a matter of seconds all over the ground and under my hood.
