Hi,
Thanks for all your replies. I've been correctly informed that the parts I have
are pre-mod 67 but all the manuals I have refer to post mod 67.
I actually want to do this mod and so I'll need new pushrods.
At least I know what the aluminium rods are for now!

Several years ago I submitted a Modification request to PFA Engineering to
cover a revised fuel system with aluminium pipes and home-brewed tank
fittings, much like Graham's. The return feed went back via a drain outlet.
Francis made several comments. One of them was that this return route was
not the best as in the event of a serious engine bay fire in which the
flexible hoses were destroyed it would be possible for fuel to be fed from
the tank along this return line which could not be turned off. In theory
most of the tank contents could feed the fire. Raising the return point to
the vent inlet removed this possibility (unless you came to rest on the
ground inverted, tail high).

Thank you John. Hadn't thought of that. Wonder if a check valve could be
used? Andair quotes < 0.7 PSI (< 0.05 bar), Rotax requires < 0.25 bar
for whole return line. Bad idea? Clogging would give carburettor
overflow. Two in parallel?

I also submitted a modification request to the PFA along similar
lines to John but with the return into the vent inlet. It has been
agreed by the PFA subject to fuel flow tests which I have not yet
done (nor pressure).

Rick,
One kit should do for just wing closeout if the top is on. Send USPS
mailing address. It will be shipped Wed.

It is in the 2 pound can. (Yes the can of hardener or part B is a
pain to pour from, so use a 1 pint vinegar bottle with a tight fitting

the bottle though.

Hi All,
Graham's fittings, aluminum pipes, andair fuel cock and andair gascolator before the pumps, fuel flow 130 liters per hour, only one pump running. Measured that with an open return line in a bucket. That information agreed with the fuel flow indication of the plane. Added a push button to switch off the return transducer. Now, during preflight it's easy to check what the raw throughput is. There was no noticeable difference with the return line connected to the top of the tank, using the vent tube. Some pics are at http://www.europaowners.org/kit600 However during the winter stop i will put the return-flow line near the top of the filler snake, because i would like to improve the tank vent for filling. At the moment it's difficult to fill the tank to the brim.

And some other opinion on previous messges in this thread:
The andair mesh is 80 micron, not 120.
Placing the gascolator after the fuel pumps does not protect the fuel pumps and
return valves from debris from the tank. There is some kind of mesh in the pump,
and if it caches debris, it will be cluttered pretty soon. The gascolator
is designed to do just that. IMHO it is not a good idea to put the pumps before
the pumps and return valves. The dry head suction of the pump is more then then
the lowest possible level in the tank. As a test i switched from an empty
main to an almost empty reserve with only 2 liters, and it took 4 seconds to build
fuel pressure back to normal. Before the carbs are filled and the engine
is back to normal life however, takes another 2 seconds of missing heart beats.

Jos Okhuijsen

tank breather needs to be at least 3/8 aluminum (to avoid static build
up) and best place is near the top of the snake. Is that where you have
it Jos?

Hi Graham,
You made it yourself, and supplied me with the materials remember ? :-)
I think it's smaller then 3/8. To resume: In the smaller top opening of the tank
i have an adapter with a breather tube and a siphon tube for the long range
tank. The breather part goes to the side of the top of the snake. An air vent
tube is connected to the top of the snake, with a 5 way manifold that adds the
sight tube, the long range tank vent and a return valve to the cockpit air.
That return valve should save my butt in case the vent tube opening to the outside
world gets blocked by insects or ice. At the moment i have a T splitter in
the pipe from the tank to the filler side, and the fuel return is connected there.
All works. But i will give the fuel return line it's own top of the fuel
snake entry, and do away with the t junction. That hopefully will improve the
ease of fueling up.
Regards,
Jos Okhuijsen
