Considering the difference in price of gas in Canada vs US, I'd hope it's better quality ;).

I didn't realize high-test doesn't have ethanol. Years ago, i was told to always put premium gas in the toys. But that was to get a longer shelf life.

How can gas have a shelf life of only 30 days? It just spent that past 2 billion years in the ground.

Just a question, but does anyone know if they're running ethanol fuel in China?

Here's a great link to find gas stations that sell the good stuff, another source if your area doesn't list a station is an small airport.

Right now, it isn't so much the short shelf life of the gas, it's the ethanol additive in the gas causing problems.

Looks like that the tarp has to go . Still not sure why the additive didn't do it's job but maybe more condensation then would ever be expected to do. If it was from condensation , would that travel all the way down the fuel line ?

I would think, the lines should be fine, provided they were ful of fuel. No air means no condensation.


Food for thought..
We buy cheap products, made in china. When they fail, we simply throw them out, curse a few times about
"Made in China junk". And run out and buy another one. (because it's cheap enough.)
Is the problem the junk they sell us, or, is it, that it won't work on our fuel?

Al, looking at that picture I have three thoughts.

1. Aw, nuts
2. Your tank will vent (and suck in moist air less) if it's full
3. If you shake that peanut jar, how long before it settles back out? I have seen some misc stuff online about shaking your gas can or stirring what's in the tank before running, just to mix everything back up...

That's the strange thing , it wouldn't even fire at all until I drained the fuel bowl and lines and replaced with fresh gas .

It starts at the tank, a little at a time gets into the system,settles in bowl, collects until there enough to cause either gunk, or won't fire. I'm in the oil business and see it a lot (water), but with fuel oil it turns into a black slime product that clogs the filters.
It's just a matter of time until someone comes out with a cheap drainable aftermarket water separator for small engines.

I have read that the ethanol is only a 30 day shelf life.....yes it did spend millions of years in the ground, but all the additives screw it up.
I don't have to worry about the fuel going bad in my truck at 15 MPG!

That's a great idea :thumbs: I did a web search but didn't come up with anything I thought would work. Might be hard because it's a gravity system .

I wish all fuel tanks had a low spot, or "sump" for the water & alky to settle into, along with a petcock to allow easy draining of the stuff! Having the fuel valve in the bottom of the "main floor" of the tank, above this sump.

There's another good idea , run a second pickup a little off the bottom for the carb feed and use the original lower one for a drain-off . How about one of those motorcycle petcocks that have " OFF-RUN -RESERVE" You could use the reserve as a drain . I think the bung would have to be 3/8"pipe though , Al

Sounds like water to me. If you leave the tractor sitting for a fairly long time with the fuel tank partially full that will happen.

A partially filled tank will allow condensation to form, and with yours being under a tarp, that probably contributed to it.

if you are going to leave a tractor sitting for a long time, you should either drain the fuel tank or fill it completely. It would also be a good idea to shut off the fuel and let the engine run to use the fuel in the lines and carb as well.
