Back on line now, been in hospital for a week with pneumonia, etc. There is
something very simple you can do about this ethanol stuff. Go to Wally
World and get some Sta-Bil ethanol Treatment. Made the trip to Kentucky
with it in my RV tanks, put it in my lawn mowers, little honda scooter, BMW
road bike, and -- used it in my gas of the 912 slingshot. Been using
Sta-bil for years and years and it is great on everything. Now, this new
stuff is meant for the ehanol deal. Go on the websites about this stuff and
read it. Use it or weep later. There are also brands for Marine use which
has more water hazard than we do. This is one additive that will mix with
oil or not, dont matter. Check it out. You wont be sorry. I think it
makes the 912 start better and if you were at the factory, you KNOW it
performs. Hope this helps. Check it out!!!! Ted Cowan, Alabama Slingshot
912.

Ted, Glad to hear you're back in service, pneumonia is no fun. Good tip on
the Sta-bil, thanks.
We're lucky, perhaps because of the aircraft industry here in Wichita, we've
not been subject to the ethanol swindle yet. Water in fuel, or the fear of
it, can still be handled by a 99 cent bottle of gas line drier.

I googled Pournelle -- here 'tis
Pournelle's Iron Law of Bureaucracy states that in any bureaucratic
organization there will be two kinds of people: those who work to
further the actual goals of the organization, and those who work for
the organization itself. Examples in education would be teachers who
work and sacrifice to teach children, vs. union representative who
work to protect any teacher including the most incompetent. The Iron
Law states that in all cases, the second type of person will always
gain control of the organization, and will always write the rules
under which the organization functions.

Grant -
Following the advice of someone else on this List, I made a homemade
gascolator using PVC. As you correctly observe - simple, cheap,
effective! (I'd like to give credit to whoever it was that I copied it
from, but I forgot who it was! Was it you, Richard P?)
I used a 2-inch long piece of 1-1/4" diameter schedule-80 PVC, with end
caps glued on. Drilled two 3/8" holes opposite each other near the top
(thru the end cap), and screwed a brass fuel barb into each hole. On
the bottom PVC cap, I drilled another hole in the center, and threaded
into it a Curtis drain valve. I installed the gascolator so that the
drain valve pokes out thru the fabric, on the belly of my Kolb. (Which
also happens to be the lowest part of my fuel system.) Easy to take a
fuel sample from on preflight.
I used fuel-proof thread sealer goop (a Permatex product) on the 3 holes
where brass hardware is threaded in. It's been installed for over 3
years now, and I've never had a leak. More details are in the archives
- this thread has been discussed before.
To answer the question of gasoline vs. PVC - before making this homemade
gascolator, I set out to prove to myself that PVC would not be affected
by gasoline. I filled a glass jar with gas, and dropped in a short
piece of PVC pipe. I let it sit for several months. No discernable
degradation to the PVC.

"pj.ladd" chides: << You can get too hung up on all the little things

Where are you going to stop? All this fuss a few weeks ago about fitting
an extra fuel pump. What for? Pat >>
Pat -
I am one of those whom you speak of who gets all hung up!
In 1992, I was forced to make an emergency off-airport landing in my
Tri-Pacer because of vapor lock in the fuel line. I was trying to climb
over a mountain range in the middle of a hot summer in Arizona, and
things got so hot in the engine area that bubbles began to form in the
fuel line, causing the engine RPM to begin surging up and down (mostly
down). The Tri-Pacer has no fuel pump - it relies on gravity feed from
the wing tanks. I firmly believe that, had a fuel pump of any kind been
installed, that Lycoming engine would have kept running.
So now, I'm making up for it by having TWO fuel pumps in my Mark-3 - the
mechanical pump on the 912, and a Facet electrical pump. Just because I
can! (Since I built it.)

The connection at the bottom of the strut has lots of slop in it. The bracket on

Do I need bushings to take up the slack or is it supposed to be this way?

No ****. Rotax and HKS both allow 5% ethanol blended gas. 8 ounces in 1280
to 1536 ounces (depending on whether I'm flying the MkIII or the trike) is
.625% and .521% respectively. I don't think it's going to hurt anything and
I've watched it blend in a water drop caught in the fuel filter almost as
soon as it hits the tank, so yeah, I want to do that.

I'm not terribly worried about ethanol, since all I can get here is 10%
ethanol gasoline, and I've had no problems other than the need for jetting
adjustments, but since the first part of the message referred to concern
about ethanol, I was pointing out that drygas IS alcohol (isopropyl, or
sometimes methyl).

That's encouraging. All the chemical compatibility information I've found
shows PVC compatibility with unleaded gasoline and ethanol as only
"fair"... "good" for leaded, and "excellent" for "high aromatic gasoline"
(whatever that is). CPVC (the typical tan plumbing pipe) is listed as
worse, only "fair" for all types of gasoline. Makes me leery.

If the connection rattle bothers you or you figure the wear might be

squeeze a little RTV in the area. -that is if you don't do a regular

I'll be transporting it to the airfield at least till spring so lots of folding

I don't understand the design if thats the way it's supposed to be. There's an
extra 5/16" of play in there right now.

Make for easy alignment of the fittings when setting up. I think John H said

There is an equal amount of play at the main spar connection although
the aft connection prevents
any shift other than normal expansion.
The lower (strut) play is exclusively lateral so doesn't change
geometry.
It usually finds a happy spot to rest and you won't notice.
