Fuel Leak

[KenE]

Hello everyone, A litle fuel problem.
1993 6.2L
I have a leak at the top of the filter mount assembly. I replaced the water bleed screw about 6 months ago. When i blow fuel residue off filter block, and start the engine i am getting some diesel mist when i hit it with compressed air again. Is it possible that the heater is leaking or should i go ahead and get a new bleed screw?
The rubber on the bleed screw is still soft.
Suggestions?
Thank you,
Ken

Could be the heater leaking, there are a few places that it can leak. I'd suggest removing the whole assembly from the back of the engine and taking a closer look. You may just end up replacing the whole assembly.

Look for wires that are swollen going into the WIF sensor and the heater assembly.
