Are you sure its leaking from the bleed screw? Do you know about the heater and the overheating problem with the housing? This is a very common problem with our fuel heads. The fuel heater wire is located on the housing on the right side "drivers side". There are 2 wire connections on the housing. I live in FL and don't need the heater, so just keep it unplugged and taped off with contact grease. These heaters can over heat and cause leaks and or fire
. in worst case..
Unplug the heater wire and if there is fuel in the plug socket thats your problem on loosing your fuel prime. If its already leaking you will need a new housing and may concider an upgrade? If its the screw seat in the housing, an o-ring for a temporary fix might help, but don't play any games with the fuel. Please let us know what you do. Oilburner
