The Murphy Builders Site

I am trying to figure out a preliminary plumbing plan for the
between-the-seats area. I want to use an Andair valve. I will have a center
console between the seats to cover the controll cables. At this point I see
2 placement options. One would be horizontally mounted on top of the
console. This may be a tight fit with fuel lines and cables in a 4" wide
console. I will also have the hydraulic pump between the seats aft of the
console. Option 2 is to mount the fuel valve vertically, below the
instrument pannel, on a center pannel that would connect the instrument
pannel with the center console. This would put the valve about 8" off the
floor, come to think of it, either option will raise the valve up from floor
level. So my question is how is this going to effect fuel and water flow in
the lines? I assume with all the head pressure from the wing tanks, the fuel
will not have a problem flowing up hill a bit from the floor before going
forward to the firewall. I will have low point drains between the tanks and
the selector valve, so the vertical section of plumbing shouldn't be a
problem for water draining. Am I right to assume any water forward of the
selector valve will drain forward to the gascolator and be taken care of
there (assuming the line has a down slope as it goes forward)?
Thanks
Jesse

One consideration might be that inpectors could want a water drain in
EVERY low point of the fuel line which you seem aware of. And not just
water from the fuel tank as they may even be concerned about water
separating out of the fuel in the line and freezing during extended
seasonal parking. Seems unlikely to me but I guess it could cause a
partial blockage. Another is that you should avoid any high points for
air or vapour to collect in and restrict liquid flow. An upslope to the
valve and a downslope to the gascolator could be a problem. Gets more
difficult if you are catering to tailwheel and also floats. And of
course every right angle fitting will reduce the flow a bit.

The simple MAM design has its advantages.

Thanks Ron & Ken,
I have considered the extension, I just wanted to save the extra $100. and I
was hesitant to add more possible failure points to the valve. It sounds
like that might be the best option though if I do end up using the Andair.
My reasons for wanting to use it are; A) putting the selector in front of
you where it will be in your scan. B) Having a fuel shutoff closer to the
firewall in case of engine fire. C) It looks cool.
Practicality may win out, but I haven't given up yet.
Jesse




Have you considered the extension rods Andair makes for their valve
selector switches? You could place the selector some distance from the
valve. See http://www.andair.co.uk/system/index.html

Jesse,
I have just finished installing an Andair fuel valve, without extension
shaft, in the floor between the front seats, forward of the flap handle. I
made a support web of 0.040" steel to position the valve just under a short
section of the 9" wide center floor panel. The support web allows you to
get under the valve to wrench on the valve connections. Since the valve
handle and escutcheon plate are mounted at floor level, I've added a 4x4x2"
hinged box over the handle to keep the shoes and coffee out of the valve
area. The box has a plexiglass lid to view the handle/valve positions. I'll
email you a couple of pics if you like.

Jack,
I would love to see some pics. Post them to the archives if you can.
The Rebel floor is only 2" deep. I think the SR has more room under the
floor, but I would like to see your installation anyway. I have sprouted
many ideas already from looking at Moose and SR construction pics.
Thanks.

Jesse,
It's difficult to do anything under the floor if there is only a 2" space.
The SR/Moose has 6"under the floor. For info I have posted 5 pics of the
Andair fuel valve installation in the SR/Moose section, file 113 S/M Fuel
Systems.The input lines to the valve are 3/8" tubing and the Andair output
line is 1/2". I have yet to add the fuel boost pump. Trying to decide where
to put it, ie, in the cabin or on the firewall.

Jack,,, I kinda did a similar installation (I used a Cessna control valve
not real large would probably fit in a 2 inch area) on my MOOSE. I went
from the control in the center to the large area on the right under the seat
put the drains system next and then put the boost pump went up to the
firewall from there. Lots of room and was out of the heat from the firewall
area. Can post photos if you are interested.. Dale SR=033
