Rockwell Posted February 15, 2018 Share Posted February 15, 2018 2011 MP8 suddenly started losing prime. This did not happen slowly over a period of time, but rather very instant. I can now see it is leaking fuel and it seems to be coming from behind the CCV turbine separator on drivers side of engine. Almost as if its coming from the lower mounting bolt of the separator. Very tough area to see. Pump is dry, everything above is dry. Anyone know what's back there? Fuel line or fitting or something? Thanks for your help!

Rockwell Posted February 17, 2018 Author Share Posted February 17, 2018 Just a simple follow up in case it helps another down the line. Turns out there is a small metal fuel line that runs behind the separator along side the block. In my case though, oil was leaking from the gasket between the CCV separator and the block. Needed a new gasket. Simultaneously, the vent tube from the CCV had rubbed a small hole into a fuel line below, hence my fuel leak.
