[rebel-builders] - fuel venting

Post by Mike Davis » Sun Feb 19, 2012 10:39 am

I plan on venting my Moose like the factory demonstrator was done... one of
the aluminum threaded plates like is used for the fuel outlet and site
gauges is mounted in the top forward corner of the fuel tank... screw in an
AN fitting, flare a J tube and screw it onto the AN fitting. If the tube
gets bent or damaged, unscrew and replace, simple. Put one of these on each
tank, then a cross vent line between the tanks.

If I may suggest, take a look at a Cessna 177 it has very little
dihedral as does the Moose. It vents at the wing tips as I recall the
right tank is vented from the outboard high point over to the left wing
tip. The left tank set up is the same and vents at the right tip. This
reduces the 150/152 type of drip problem when parked on the ramp in a
left wing low condition. The 210 also vents at the tips but I don't
think it cross-vents as the 177 does.
Some of you may want to look into the ideas that Cessna used here to
help with a proven idea. A look into the service manual and pilot
operating hand book of these models will give you block diagrams and
schematic diagrams, and the parts manual will show the complete lay out
of all the lines, parts etc.

Also take a look at the inside of the gas caps. In the event of a vent
problem the little silicon rubber "mushroom valve" is designed to allow
air to enter the tank as fuel is used and blocks the out flow if the
tank is trying to over-flow when parked on a slope and fuel is trying to
flow from the high tank to the low one (it's a gravity thing. This was
a service letter item years ago and I think a darn good idea.

I plan to look into the two systems before I close up the wings on mine.

I have used Cessna, Piper and Beech systems ideas in the planning for my
Moose. Mostly I like the idea of using proven engineering in areas
where mistakes can cost you in more ways than just the pocket book, if
you understand my drift here!

[rebel-builders] - fuel venting

I used to have a Cessna 170A years ago. It had no wing
dihedral. It used a J tube on the center of the
fuselage top (half-way between the wing tanks). I t'd
into the fuel tank cross-flow line. I think this is
similar to what Murphy recommends in the SuperRebel
builders manual.
