First I want to thank Scott
He did a great job on a Zen for me, the boat is fast.
But I could only get two laps and it'd quit.
I just installed a new sullivan tank, with the black rubber stopper, and running coleman fuel.
The stopper disintergrated and plugged the carb screen.
Any one else have trouble like this, I thought the black stoppers were for gas.

Plugged primary screens will indeed kill an engine ... bummer on that !
Look forward to seeing hearing more positive posts once you get dialed in and able to start the finer tuning work

If you need assistance, you only need ask.


Odd on the stopper if current Sullivan inventory , have had brown/black ones and remember one type doing as you state ... sadly don't remember which it was ?

I tested a black and a white plug immeresed in the fuel I took out of that tank, 1 1/2 days
there seems to be no effect, so the black plug must be for gas but what are these white plugs for?
The coleman fuel doesn't effect them.
Pat

I had same issue - I think white is nitro fuel

I switched to Buck bags (Thanks Scott for idea) and have never had any issues since

I did note that reg gas seemed ok with black but coleman ate them

I now run 96 octane Marine gas (no ethonol) and have never had a issue since - beside coleman is 20.00 a gallon here

I asked my son (better memory than me) he said gas is BROWN and showed me on Horizon

I'll see if I have any and send them to u if u pm me your address

guess u don't need them u been here since this was posted

White ones MOST DEFINITELY the Alki/Nitro fuel stoppers

Ive got a tank around in the shed somewhere, the original 'black' stopper did fall to bits with pump fuel. I think it has the tan stopper in it now, would have to have a dig for it.

I would have replied earlier, was working on the computer hook up.
Thanks for the offer, i'm going to go with the black and later test the white.
I had a black one in a tank, running gasoline for two years with no trouble.
I bought an inline fuel filter, it's clear plastic, and can monitor the progress.
I'll let you guys know what I find out.
Am having trouble testing the boat, the Indians are fishing the river, there are nets all over.
Pat

You are welcome to the 2 brown gas one's I have - I'll send them free (just a stamp no big deal)
I don't use those tanks anymore - hate to see stuff wasted

No biggie

Have a good 1 ................. show us some video - Scott's stuff makes boats fly ....

Some of the fuel bags have a white side-pin fiber material that will dissolve in gas. The next bag i order had a bolt threaded in place of the fiber material But the bag gave off a creamy white snow,inside the bag. Buck bags are used now.
