Fuel selector location and belly drain

Mike Kimball · Post by **Mike Kimball** » Fri Feb 17, 2012 9:37 pm

I would like to use the Andair valve with Left/Right/Both/Off positions, or
a similar valve. I started looking at my fuselage and due to the elevator
push/pull tube, control torque tube, and rudder cables the only place on the
floor I found that looked like it would work was in the gear torsion box to
the right of the left hand gear mounting. It looks like it would end up on
the floor between the pilot's legs. Another possibility would be on the
left hand wall of the forward fuselage in the same spot Piper puts the valve
on the Cherokee series. I prefer the wall so that I won't have my head
under the panel while switching positions (if I ever do: if the tanks bleed
evenly it'll probably always be on BOTH). Any concerns about the fuel lines
running up the wall to the valve, then back down under the forward floor and
forward to the gascolator? Where is the valve on the demonstrator?

I want to use flush fuel drains on the belly to prevent being damaged by
rocks off the prop or main wheels. The flush drains have a stem that sticks
up and makes fitting the tee more difficult. Can the stem be up inside a
piece of pipe leading to the tee and still work OK?

I found a local company that sells a jillion fittings going from 37 degree
flare to pipe thread in any combination you can thing of. They are not AN
but they look to be very good quality. In fact they cost more than AN.
They are steel and plated so they look just like AN bolts with that sort of
gold color. They had exactly what I needed, which is not even available in
AN. Any concerns with using these fittings. (A local IA sent me there when
he could not provide what I needed in AN. He said it was a homebuilt so I
wasn't constrained like he would be with a certified airplane.)

Mike,

We installed our Andair valve (FS25x4 - this unit is for 1/2" fuel line)
between carrrythroughs 2 and 3, in the centre so that both pilot and co-pilot
can reach. We found this to be the best spot and it will not interfere with the
torque tube or cables. We ran 1/2" fuel lines down from the tanks inside the
rear door posts to the sill section where we put a tee fitting with a drain
valve (one on each side) then ran the lines up to the front (both sides). We
installed a banjo fitting on the bottom of our Andair unit as there is no room
to bend the fuel line that goes to the gascolator on the firewall. We will try
to take pictures and upload them to the builders site.

Mike you're describing JIC hydralic fittings. They're made for thousands of
pounds working pressure. If you're not bothered by the weight penalty they
are certainly able to handle a rebels fuel pressure :) This is high quality
hardware and I have several similar fittings on my plane.

Great news. I wanted to put it exactly there but thought there wouldn't be
room above the torque tube and cables. I have run 1/2" lines as well
exactly as you have done and planned on the FS25X4 as well. You have not
installed boost pumps apparently. They are probably not required. Not
knowing for sure, I was going to install them basically for peace of mind.
Maybe you can talk me out of it?

I've installed the Andair FS25x4 (1/2") just aft of the gear torsion box and
in the center. I've offset it enough to allow clearance for the elev. push
tube. 1/2" lines from the tanks to the valve, then to a weldon fuel pump
under the pilots seat with a built-in drain. I haven't settled on a location
for the gascolator, probably on the firewall but maybe between bulks 2 and
3.
