Engine Mechanical problem
1998 Ford F150 6 cyl Two Wheel Drive Manual 125000 miles
I bought a this truck last fall and quit driving it in November. I just started driving it again. The first day I drove it I noticed something on the drive way as I backed out. I thought it was probably some water from the rain during the night. On the way to work I smelled gas and I looked under the hood once ot twice to see if I could see where it was coming from but without any luck. On the second day the same thing some drips on the drive way as I backed out and a fuel smell. On the way home I stopped to get the mail and from across the street I saw something dripping underneath the truck. So I went to look closer. Fuel was running down the transmission at an alarming rate. When I got the truck in the garage later I turned the engine off and crawled under the truck to see if I could see where the leak was. I didn't see anything obvious but did see something in the fuel line that didn't look right. In the hard line fuel line from the tank and the fuel return line there is a length of black rubber tubing about 18 or so inches long on the drivers side vertical section from the transmission up the left hand side of the engine. The lines were touching the cylinder head. I moved them around so they weren't touching and started to look for a fuel line repair or replacement kit. I wasn't sure which line was leaking so I turned on the key but neither line leaked. So I started the engine and still neither line leaked. The leak seems to have gone away. I am concerned because I don't know the source of the leak and am concerned it could return in a more catastrauphic way. Is itr possible that the engine head was heating the fuel in the line causing the pressure to increase and there is a pressure relief valve somewhere?
