Fuel tank sight gauge routing

[Richard Iddon <riddon@btinternet.com>]

I have been surfing the archive ref. the fuel sight gauge positioning and
tubing routing.  The favourite seems to be to route the sight tube up the
seat back then take the tube across the seat back and connect it with a 'T'
fitting or a dual vent fitting outlet to the tank vent.

Am I reading this correctly,  are there any problems with this set up and is
it an 'approved' mod or is approval not needed for this?

Also any other suggestions??
