I would suspect your sending unit is defective ,as mine was. Mine shot
craps in about 8 months. Disassembly of the sending unit(with a hammer )
revealed a cheap misaligned impeller,that had worn off one of the sides thus
giving inaccurate readings and then finally,none. I have a replacement
sender(warranty) coming but they are behind in their orders.(many months) After
looking on the net,I believe failures of these sending units are fairly
common.
If I ever get mine working again,I will just use it as a reference for
bouncing fuel gauges as it has never been very accurate or easy to adjust.It
just beeps and the digits don't change without constantly pushing the
buttons. I guess you get what you pay for.

Jack,
Leonard is right. I had forgotten but mine did that too. It just
swapped over to liters all by itself and my readings were also bad. I did the
reset and until it crapped out,it was back in the ballpark.

THANKS ALL.....
I will double check the settings. (I thought I had it set on Gal/Hr). the sender
is a new replacement working with the old guage. I did find a funny loop/bend
in the fuel line near the transducer that I will remove this week and also install
the new guage (just in case the new transducer and guage both have both
changed 'as a matched system' over the last 2 years.

Thanks again to all.

Hi all.
I just went to the hanger and looked at the F210. I do not know how but it got
set to lit/hr. I reset it to gal/hr and will double it later this week when I
get a chance to fly. I have added this to my preflight checklist.
Jack
Thanks for suggestion

Chris,
As noted by Jeff, being nose heavy does make a difference in your speed. I carry
my tools and ground anchors, etc as far aft as possible in my luggage area.
It does make a difference...just how much will depend on how far forward your
CG is.
Another easy place to check are the flaperons. If they are trimmed to low, they
will create a lot of drag and slow you down. That would not require a level
floor, etc. Refer to your assembly manual and step through setting up the deflection
on the flaperons.

| Subject: | Fuel Flow Problems, Again! (Vixen, Series-5) |
We just returned from an 800 mile trip to our favorite flying destination, High
Valley Resort in north GA. We developed a fuel flow problem while enroute.
A little history. Two years ago I had a fuel flow problem (actually on the same
trip!) that was caused by my new paper filters (located between the wing tanks
and the header tank) air locking and not allowing fuel to flow. We completed
the trip using just one tank. After returning home, I discovered that if I
blew up through the fuel line, causing the filter to fill with air, it would
not gravity flow! After either sucking on the line ( or blowing on the gas cap
vent tube) to force the fuel to flow, it would flow without restriction. This
was repeated numerous times, on both tanks with the exact same results! The
filters had been replaced just prior to this event. This was also tested with
new filters with the same results. After that, I returned to using the filters
with the glass sight tubes.
OKpresent day... I filled both tanks to the brim prior to our 400 mile, one way,
flight. After about 45 minutes Kathy noticed there was no fuel in the header
tank vent line. The right tank level was low and the left one was full (could
not see the fuel levelabove the sight gauge). We checked and both fuel valves
were on and we cycled them several times. I reduced power to the engine
and set it up lean of peak to reduce the fuel flow. Shortly, fuel appeared in
the vent tube (yes that was a relief!). Fortunately we were at 9,500, talking
the Atlanta Center and had an airport with easy gliding distance (which also
provided some peace of mind).
After going back to full cruise power, the fuel level in the vent line started
dropping. We turned the working tank off, pinched the vent line so it would force,
hopefully, the fuel in the right tank to be sucked. After a few seconds,
the left tank filter (which was filed with air) starting showing some fuel movement
and slowly filled about way. I kept the vent line pinched for about
a minute. Fuel flow was established on the left tank, but still not enough to
fill the vent line. I turned the right tank back on and the vent line filled.
I closed it again and then slowly opened it to allow partial flow and kept
the fuel level in the vent line visible for about 30 minutes. After several gallons
of fuel was pulled from the left tank, I opened the right valve completely
and the vent tube filled. After that fuel flowed from both tanks and was
not a problem.
Heading Home We stopped for fuel while heading home. This time the same thing
happened, except the tanks were reversed! Right tank would not flow. We did
the same thingpinching off the vent line and forcing the system to suck from
the non-flowing tank. Again, this was met with success.
I am at a complete loss! The vent lines on the gas caps are open (checked with
each fill-up and also with a pipe cleaner, etc). All my flexible fuel lines
are 3/8 marine grade lines (vent line is clear Tygon). No lines are pinched.
Once flowing, they flow with no restriction. There are no loops, etc in any
of the lines. I would appreciate any helpful information regarding this problem!
AlsoOn the return leg home this afternoonMy charging system went out! I just hope
it's not another alternator coupling/clutch thats gone bad!
