aux tank mod
I have an M4-220C with standard two tank 40 gallon fuel system. I would like to have the aux tank configuration. What am I looking at as far as cost, man hours and difficulty to do this modification. The 40 gallon set up has worked fine but would like to have more reserve for some extended IFR and VFR to more remote areas i.e. up to Alaska. If anyone has done this mod it would be nice to hear your thoughts. Thanks.

Mauleairinc may have a price for the aux tanks kit.
Some wings were produced with the extra tubing installed (vent and feed to main tank). You will need tank bay bottom skin supports, tank top cover, tank, tank cap, tank cap fairing piece, tie in straps and turnbuckles, tank bay side rib change or nut plate installation, aux pump, anti siphon valve on vent line, wiring to aux pump and to sender and for gauges and panel switches.
Might be cheaper to buy used M5 wings with tanks and do the M5 to M4 wing mod.
