My 1950 1300 has the gas tank in the cab. I have to keep the tank topped up until I fix the gas gage. When I leave the truck out in the sun on a hot day I see gas dribbling out the filler cap at an alarming rate.I figure this is due to the gasoline expanding.Aside from the cost of gas I worry about a fire. Should I invest in a new cap ? It looks like the original one to me.Or does any one think it's something else ? Thanks for any help . Jeff
