Fuel Leak

[Niall8or]

I have a 2000 F250 7.3 (California emissions) and I have a fuel leak when parked, ONLY when the block heater is plugged in. Any thoughts?

I dont see how this is only doing it when plugged in. You sure its not when running?

[Niall8or]

Not a drop on my driveway or my regular parking spot at work...but as soon as it's plugged in, big spot/spill on the driveway. Put cardboard under the truck when not plugged in, nothing. Plugged it in last night, fuel spill. I don't get it either!

Wow thats a strange problem I've never heard of this.

MAY WANT TO CHECK THE FUEL FILTER HOUSING DRAIN VALVE.HAD ONE CAME IN LAST YEAR TRUCK WARM DRIPPING FUEL PAST THE BALL INSIDE THE DRAIN VALVE.THE ONE WITH THE YELLOW LEVER TO THE LEFT OF THE FUEL FILTER HOSING IF YOU ARE FACING TOWARD THE FRONT OF THE ENGINE.

how do you replace "FUEL FILTER HOUSING DRAIN VALVE"? This seems to be where my leak is coming from. Does the whole assembly have to be replaced?

[bec]

you can replace just the valve that is located on the side of the filter housing.good luck on finding one, dealership around here says they are on back order.

I know you said fuel leaking, but could it be antifreeze. The only thing the block heater in connected too is the oil cooler housing just above the oil filter. Fuel leaking when the block heater. I don't have a clue.
