what we did, is to introduce a "Gardena"-flexible plastic hose with a
diameter of 12mm into the filler hose and forward to the tank's highest point
on ground. Filling-up 80 liters takes me now about 5 min. (before > 20 min!).
The hose has to be tied to the fuel cap otherwise it will slide into the
tank.
Yes, we tested the Gardena material during one year and it will not disolve
with Avgas or Mogas...(but of course this is not PFA approved....)
