Ok, what fancy new tool can I buy, or what diy frankentool have you used to get at and tighten the nut for the the fuel vent line elbow fitting that goes through the 902 bulkhead (R9A)? It's so tight that I can barely get my fingers in there, let alone a crows foot or socket. I know there's probably a painfully obvious answer, but I haven't found anything that will fit.
