Im running my fuel sight gauge up the back of the starboard seat. The tube then
has to go aft towards the vent. One could run it across the top surface of the
cockpit module adjacent to the headrest. But there is quite a decent space
between
the top of the tank and the undersurface of the cockpit module, so Id like
to take the tube across the area between the headrests in that space. That
seems a neat and tidy way to keep the tube out of the way. However, I understand
that contact with fuel makes the tank swell up. Im concerned that the tank,
once filled with fuel, will expand so much that it will crush the tube and close
the vent to atmosphere.
Does anyone have any idea of how much the tank expands vertically? Will it swell
until it touches the underside of the cockpit module?
In this connexion, it occurs to me now that the flange of the analogue fuel
level
sender might also foul the underside of the ply floor in the starboard headrest
if the tank swells a lot. I think I made the hole in the ply floor just big
enough for the top part of the sender, not the flange. Has anyone experienced
any issues with that?
All information on the topic welcome.
