Ron,
As for the fuel vent setup in the top of the filler tube, Spruce have a rubber
barb
washer that suits a 90 degree elbow. This washer with barb attached is a bugger
to install into the appropriate sized hole, but once installed, and the
aluminium
elbow is pushed through, well it aint going anywhere! Also, it can be inspected
each time you refuel, to ensure you can still see the barbed portion of the
elbow
sticking through the internal part of the rubber barbed washer. With this elbow
you
simply push on a nylon/rubber/whatever hose that suits you, and with it not
normally having fuel in it, albeit exposed to vapours, it should last forever.
Hope
this helps. Its in the Spruce catalogue, but I don't have one handy to be able
to
refer you.
