[QUOTE="Rob D, post: 970155, member: 705"] It is def. in the fuel system you can hear the hissing stop as soon as the pump stops priming with KOEO. I am going to try aftermarket flex fuel lines to the front of the heads. No way I am pulling the manifold off. If that doesn't fix it I will buy a new stock housing and upgrade to blue spring and replace all orings etc. I am pretty confident fb leak is happening at the fuel bowl area. [/QUOTE]
