Direct quote from CAR 3:

(a) The word "fuel," the minimum
permissible fuel octane number for the engines
installed, and the usable fuel tank capacity. (See
§ 3.437.)

I'm cheap so I used these http://www.aircraft-spruce.com/catalog/ ... ards11.php and added "usable fuel 18.5 gal" with a tape embosser. So far they've lasted 14 years and the embossed labels were replaced by Ptouch labels about 10 years ago. My airplane is never refueled unless I'm there.

For those of you with fuel STC's, you should re-read your STC installation instructions to be certain your fuel placard meets those. (I'll bet there's an ASTM specification which must be listed.) :wink:

I'm just guessing, but I'll bet bluEldr refuses to carry any Porkers in his travels to the outback campouts to which he flys. (No Ham Fat) :lol:

Here is the page from the EAA Mogas STC that covers required placards.

Please note that the EAA placard must be in addition to, and adjacent to, the existing, required aviation gasoline and capacity placard.

I guess I'll just have to live with the consequence when they find out I have both combined into one decal! :roll:

Oh wait, Maybe I could cut the decal in half just above the "or" and then put usable gallons on the bottom of the top half of the decal. would that make it legal? I would make sure the two would not touch so you could see they were separate or maybe I should put a black line on the bottom of the top half and a black line on the top of the bottom half. But wait do I need the usable fuel as part of the top half decal or can it be adjacent to the decal. I'm sooo confused :cry: Been flying illegal all these years.

johneeb,
You will notice that the EAA STC for "Unleaded" mogas is dated back in May 1984. I believe that was shortly before the federal requirement for the removal of all lead from automobile fuel. The EAA STC program was sponsored by a particular vendor of mogas whose products were avertised as "Unleaded" even prior to the federal regulation.
This particular company did not market out west here in California and as a result we generally bought the Peterson STC, at $.50/HP., since it did not limit you to an unleaded fuel which would have been unavailable locally. We were still using leaded auto fuel here and all regular grade fuel was leaded, though still not as heavily as even 80/87 octane av gas.
I remember that when it was announced that all mogas would have to go unleaded there was a ton of dire predictions and hand wringing about valve seats and "Lubrication " of valves, etc., none of which turned out to be the case.
It was pretty much the same when they started requiring "oxygenated" fuel containing ethanol, ethyl alcohol. I have two later ('96 and '99) Fords, a '63 Ford, two 200 cc Vespa motor scooters, a 250 cc ATV, two generators, a pump, and a lawn mower, all of which seem to be thriveing on this disgusting alcohol laced fuel. I , naturally, would much prefer pure gasoline, but it is just not locally available here, so I make do with what I can conviently acquire. I never noticed any adverse effects on my airplane either.

Bruce, what material should I use? What thickness? I see cork, nitrile, urethane, and in many different thicknesses. I don't want to spend over $100 for the McFarlane gaskets, but I sure don't want to experiment, or have to do the job over, either.

I used cork. The tank gaskets as I measured indicated 1/16t" but I successfully used 3/32". I used cork but Buna-N would be appropriate. This is what I noted on my drawings at the link.

Ok, here we go! Fel-Pro 3018 cork-rubber, 10" x 26", 1/16" thick. $7 at AutoZone. I'll use the money I saved to buy a leather punch to make neat holes.

TOTAL capacity must be labelled/used at the filler (although useable may also be posted at anytime.) Useable fuel is placarded inside the cockpit.

Just curious how many gallons you are able to get into those 21 gallon tanks. 19.6 is max I can get.
