HI
Why not make your own it's not hard just drain your tanks and get a bit of wood 25/5mm or so and tape a bit of clear tube to the side make sure that the bottom of the tube is level with the bottom of the stick and the top is the same there add the first 10 lts dip and hold the stick in for a few seconds place your finger over the tube and pull out, fuel will be in the tube at the level it's in the tank mark the stick and repeat again at 5 or 10 ltr intervals .And now you have your dipstick it does not take long.
Cheers Rory
