I did one on Falcon years ago I used and electronic one drill out the four inch plate like Dennis and then put the meter in the Nav station and wired it in to the VHF circuit total time about and hour and cost was about 50 bucks Well worth it nothing to move etc.to see how much is in the tank
Note the tank is not a square shape so the bottom 1/3 of the tank will be used up a lot faster
