There is a smaller gas line coming from the larger 'group' (top right of photo). This connects to a small 90 angle and another attachment. When I take hold of the assembly I can lift it up and push down slightly. When I do this I notice some gas drips from the black/silver attachment. Is this a problem? Does anyone know what this is called? How do I remove it to repair it?
It'* called your return fuel line. The fuel lines are not screwed on, therefore they seal with o-rings that are inside of them. There'* two in each line. If you put odd pressures on them, some fuel can leak out. It'* completely normal.
Kinda like if someone pushes on you..you'll have a reaction.
When I was installing headers, a friend of mine sat on the engine to see if he could help. I was fine with that even after I noticed some fuel leaked out. Then again, I was hoping for the opportunity to install some AN lines...
The fuel smell stayed there until the next day, and then the fuel evaporated.
