The lead substitute octane booster chemicals are very volatile, with low flash temps - and are brutal on traditional rubber hoses.

So i've used AVGAS all my life - a habit from Colombia where the mogas is poor quality.

I recently started using mogas - just easier really I go past a gas station on the way to my hangar.

Now I understand the gas smell comments!  I means it's not terrible but it is certainly noticeable.

Why the difference?

Will,



I used Gates Barricade hoses as recommended by Bud. Still get a whiff of smell once in a while. I noticed that I get it only at some specific speeds and traced it to the air from my vent looping around the baggage compartment and pushing air at me at my back.  



Discovering the leak at the tank vent boss and fixing it helped. Time will tell if it is really gone.



Hoping that one day unleaded avgas becomes more readily available and it doesn't smell like dead dinosaur poop so much

Sounds like you're on the money.  I also still have some smell after replacing with solid + barricade, likely via the PTFE (underflouranated tank) - Although doing the sniff test, my filler coupling rubber hoses (with the alum elbow) appear to be contributing as well.

FWIW, my still not information kit's tank (which was flouronated at the factory) I had re-flouronated by the same industrial folks in Atlanta who do the fuel tanks for the auto industry, shampoo bottles etc etc.  After the tank was done to their "automotive" level/standard, it's surface has become significantly/markedly  "frosted" in texture.  So there should be some improvement over the factor tanks - I can hope at least 

Cheers,

 Will,

 

 I use mogas almost exclusively and have lived with the smell for 20 years.   While it has been discussed on this forum that it is the hoses that are the culprit, I wonder if it isn’t the PE fuel tank that is emitting the majority of the smell.   I say that because, I have mostly aluminum fuel lines in my plane.  Yes, the transitions from the tank fittings and the fuel pump/filter assembly are hose, but that’s about it.  

 

 I fuel the plane with 5 gallon PE fuel cans, filling them up at the local station on the way to the airport.  It is surprising how much odor an “empty” fuel can emits while briefly stored in the car enroute to the fuel station.   I remind my wife of this fact when she smells fuel after opening up the canopy.  She always ask if we have a fuel leak in the plane!

Thanks guys.

I sort of vaguely remember a thread about the smell but smuggly paid no attention because MY PLANE doesn't smell unlike other people's planes.  How wrong I was!

Anyway on another note I have a Colombian homemade turbo on my 912.  It doesn't have a TCU.  I was wondering about detonation.   The chap who installed it said that nobody as far as he knew had the issue provided they used AVGAS (in Colombia mogas is "variable" quality) and indeed the only plane that I know of which did have a serious detonation in Colombia was a 912S.   It broke a piston - high compression with poor quality mogas was the verdict.  

Does anyone with a 914 have an airbox temperature sensor and if so has it ever gone above 88C?

Will

Will,

We have airbox temp and it never approaches the intervention temp - later TCU.  I know Erich has the older TCU and does watch airbox temp.
