Jim,
BTW, I am surprised how much fuel escaped from the plugged tubes.
Could you describe how the ends were sealed? Do you think it is possible
that some fuel escaped around the seals?
Regards,

We cut short sections of F4040A, SE200 and C210A filled them with auto gas
and plugged both ends. The gas eventually leaked out of all of them, but it
was out of the F4040A in a day or two, C210A about a month and SE200 took 3
months. We also put short pieces in a jar of auto gas. F4040A has
discolored and gotten much stiffer in 3 months. C210A is discolored but not
stiffer and SE200 the PVC has shrunk but the teflon liner has not changed.
So we are using SE200 for our sight gauge. For the Long Range tank feed, we
used C210A. We also measure fuel quantity with a pressure sensor similar to
Tony K's system feeding an input to our GRT EIS and the EIS calculates fuel
usage from flow transducers.
Attached is a photo of the sight gauge up the back of the cockpit module.
