Center tunnel - a busy area

[A2022]

this was a busy area for me. I routed all tubes and wires thru the tunnel. I haven't touched any wires in 10 years except to upgrade the transponder to ADSB. there are extra wires routed in the tunnel in case I need to add something simple. there are no wire connections in the tunnel, only straight thru wires.

this fuel flow meter in the vertical orientation and close coupled with piping bends is not very accurate, it bounces around but gives a good average. it's been there for 10 yrs. would I put it there again.... I don't know. I needed to tuck the fuel line as close as possible to the firewall to prevent interference with rudder pedal movement. grounding forest of tabs has been good.
