Put a sensor in there, your best insurance for leaving out a out of fuel situation
I mouted a sensor from Wema
Y can get the sensors lengh
t from 150mm
and up, mounts realy easy.
Get the depht of the tank, order the nearest sensor, before drilling eny hole in the tank make a ring that have the hole pattern as the sensor, transfer the holes to the ring and make threads for mounting skrews.
Cut the ring in the middle witout damaging the threaded holes.
Drill the hole in the tank + the skrew holes (cleanup the mess)
the ring can then easy be let inside the tank and secured with some petrol resistant sealing.
Put in the sensor, tighten the skrews , leave a thin layer of sealing all over, and you are fri to go.
My experience is that the tank (and boat) would be out of service not more than 2-4 hrs.
