My 9U D6 is leaking fuel out of the vent lines by the fuel system tower where the fuel filters are located. I'm not quite sure why this is happing, but any advice and help how to fix this would be greatly appreciated.

Thanks Woody

Most likely transfer pump seals leaking, also can be seepage from injection pump housing.

While working on the Thermostats I managed to bump the bleeder valve for the top of the fuel housing and it did that same thing

Some times the vent/drip lines all come together to one so its more difficult to tell whats leaking
