I've got two chainsaws and a blower down due to ethanol fuel. I run stabilizer, 89 or 93 octane in everything, and RUN everything regularly. I'm seriously thinking about buying gas from a bulk suppiler that is ethanol free.

I hear that Bradford, there are a few places in central Florida to buy the non-ethanol fuel. It is more $$$ and a bit of a PITA but worth it I guess. So far I have been OK using additives and using the boats often. If you let your equipment sit for long in between uses the non-ethanol might be the way to go. Problem for me now, I can't remember if I put the additive in the V last time or not.
 Five weeks since last use. How long does the fuel stay fresh?

if thats a 90 EFI Yamaha 4 stroke, then pull the intake off, its not as hard as you think, the bottom bolt is tricky. Take the throttle bodies with it. leave the VST attached to the intake. Once you have the manifold/VST assembly on the table, you can pull the screws out of the top of the vst and drop the resevoir off the bottom. Clean out the resevoir, replace the screen on the fuel pump. Take the injectors out, send them off to have them cleaned(I use injector rx), when you put it all back together, fush the mechanical fuel pump with carb cleaner, then gas. Replace the inline filter between the mechanical pump and the VST. Put it all back together, repalce the fuel line with new, install a water sep filter if you don't allready have one. I've done about 10 of these this year. I've tried every short cut, but its easier int he long run to pull it all apart and do it all at one time

Spare, that is what I have been waiting for, a definative answer to the looming question. I didn't know if the screen in the VST was servicable or not. The entire fuel system is clean/new all the way to the pump. It has a water seperator, new tank, new filters, new fuel lines and primer ball. The mechanical pump has not been touched other than to run clean fuel thru it. My local Yamaha shop is now cleaning injectors for $45 ea. I planned on sending them off to Brucato but it would be convenient not to have to. What do you think? The fuel system is nearly identical to the one on the 250 Merc EFI. I don't know why I would treat the Yamaha differently, looking for a shortcut I guess. Thanks again for your input.
Reel, not yet on your baby. Still in the planning and funds development stage.

the mechanical pump can hold a bit of trash, I ususally spray some power tune thru it and let it sit, them flush it with fresh gas. Injector RX charges $18 per injector, they have a quick turn around, but shipping takes a while, usually about 10 days from the time I ship them till I get them back. Ask the shop how they clean the injectors, if they install new screens and do they perform a flow test when done(Injector RX does). Some of the local shops around here say they clean injectors, they put them in an ultrasonic cleaner and spray carb cleaner thru them. Not the way to do it my opinion.
