Riveted left outer subpanel (F7105B-L) to the fuselage rail gusset (F-721A-L). Was able to squeeze two rivets, but had to use the rivet gun on the two inboard rivets. Tried to connect the ElectroAir MAP sensor to the MAP line, but was unable to due to the size of the fuel vent tubing and the inner diameter of the MAP sensor tubing. (1/4”) Will try to find a 1/4” fitting tonight. Modified a Z angle to aid in support of the bracket for the AFS SV-EMS-220 (engine sensor module). Not sure if this is the best solution, since I have to drill two 1/8” holes in the forward left gusset. Probably give Vans a call or email.
