| Subject: | Re: Fuel System Questions |
Your installation sounds very much like mine. I also used aluminum tubing with
AN6 fittings for everything aft of the firewall. I did have a few more fittings
than you are describing as this includes a fuel selector and a union in each
line going to the wing. The union was required to make it possible to get the
line in with the wing in place.
I can't stand barbed connections for almost anything in an aircraft. We are forced
to use them in boats and I don't like them there either. I have seen hose
slowly fail under the clamps. To make things much worse, the bing design forces
a sharp bend in the hose just as it comes off the nipple. This is an absolute
no-no in hose assembly even where barbed hoses are considered acceptable.
Given the thread size on the facet fuel pump, I didn't fight it and used AN5 size
hose from the facet pump to the 3300 pump and from there to the carb. You could
use AN6 hose, the 1/8" to AN6 fittings exist, they are just not as common.
The hose used everywhere is pre made Aeroquip AE466 with a firesleve molded in.
It has a very long life (probably longer than your airplane) but is expensive.
This is available from Aircraft spruce and will be $60-100 each depending on
length. The catalog part number is AE3663161FXXXX for -5 size or AE3663161GXXXX
for -6. This does not show up online but it is a custom order so you need to
call them on the phone anyway.
I modified both the carb, a bing, and the 3300 pump to take a threaded fitting
for all hoses. The pump is easy, one drills out the existing hole and tapes it
with a 1/8 inch pipe tap (of course one dis-assembles the pump to do this). The
carb is a bit more difficult. A new fitting is soldered on top of the existing
nipple. Pictures of all this are on photo.hubbles.com
Finally, I gave up on the bing and put in a Rotec. I do have the modified Bing.
I was planning on selling it once I get the plane flying again after the CH601XL
"upgrade".
The Facet pump is a flow through pump. It will allow fuel to flow with no power
applied when pumped by the 3300 engine pump. The way these pumps are made pressure
seen at the carb is the highest of the pressure either pump can produce,
not the sum. Thus it is safe to have both pumps on in series with the Bing carb,
if anything is safe with a Bing.

Check with Summit Racing for steel braided flex fuel hose. You need the
flexibility to avoid cracks from the engine moving around and they also have
the AN fittings.

I second the recommendation as far as the hose is concerned, but their
fitting selection is limited. Summit is also a great outlet for VDO fuel
senders and gauges.

Hi Guys,
I have changed my Zenith canopy for a Todd's version and have noticed the
gas struts are a little weak due to the Todd's increased weight.
Has anybody else noticed? If so did you change the gas struts?
Cheers
