 |
|
Filled the tank in stages and checked the sight tube as its been a bit odd and I thought I may have made a mistake in marking. At about 4/5ths full the reading goes down but the vent tube stays full. I presume due to wiggles in the pipe and when the surface tension matches the force of the air wanting to escape the bubble stays and it misreads.
I am thinking putting a larger dia pipe from the tank to to vent would cure it or maybe just a wide section (like a filter glass with no filter) might do it.
I only use if for ground fuel state assessment.
Found the seal on the electric qauge is seeping slightly, wretched thing wish I'd gone straight to the FPL5 fuel flow gauge.

I did put a glass filter body in the sight gauge on the top of the tank in the headrest and that has cured the bubble problem/false reading caused by the long low gradient back to the vent.
