You are doing such a great job with your people hauler. Just great.
Concerning the issue of air in fuel line:
I'd rather suspect a gasket to be the culprit (e.g. fuel filter), rather than an actual pinhole in the line. Other than the rubber pieces in your fuel lines are really porous.
This issue might even be caused by the cold as it makes object shrink and rubbergasjets be less flexible.
To find the leak, you may spray suspect areas with starter fluid or brake cleaner: If it revs up, you found it. (Make sure the material sprayed at resists the solvent!)
However, with really tiny holes, this doesn't work either.
Good Luck Ralf
