Is there a fuel dip tube available for the Piper Warrior II
(specifically, pa28-161)? When I flew the 172 I used a fuelhawk dip
tube to measure how much fuel I had. In the warrior there are tabs in
each tank at 17 gals but other than that it seems like guesswork. I
sure would like to find a way to more precisely measure the fuel aboard.
I searched google but could not find anything.

This is triggered because last weekend I told a Signature FBO to fill
the tanks up "to the tabs." The lineman topped the tank off and I had
to have fuel drained before I could leave within gross. This isn't the
first time that has happened to me. It would be much better if I could
dip the tanks and then simply say "put x gallons in left and y gallons
in right" and remove all ambiguity, guesswork, and depedency on
Signature line personell knowing what "to the tabs" means.
