Sorry to read about your problem with tank sealer. Unfortunately
many of the tank sealers were not compatible with ethanol when they first
came on the market. The tank sealer from Eastwood now states that it
"resists all types of fuel additives even alcohol".
You now have a tedious job of removing all the junk tank sealer from
the entire fuel system, tank, lines, and filters to restore fuel flow
volume. I would take a sample of the sealer out of the tank and see is
lacquer thinner, acetone or some solvent will dissolve that stuff and make
your clean up job a little easier.
I have tank sealer in the tanks of my Tiger and it is still in good
condition after 20 years but I only use gasoline in them.

Subject: Gas tank sealer
I have been having some problems with my Bugeye running out of fuel in the
float bowls. It started after I rejetted the carbs because I was not
getting all the top end performance I should have been getting with my
modified 948.
After a high speed run, the car would run out of gas (in the fuel bowl). It
progressively got worse until last weekend the car ran out 4 times in the
last mile home and the only way I could get a little distance was to
pressurize the tank with lung power to push fuel into the float bowls. You
learn not to release pressure too quickly to avoid fuel blow back.....
I have had an electric fuel pump on the list for a while, so I installed
that on Saturday. The car started on first crank instaed of many cranks to
get the mechanical pump working.
After initial optimism, the car died and nothing was moving again. Draining
the gas out of the tank, I had to poke a tool up in the drain hole because
something was impeding flow. I pulled the tank and it was full of sheets of
plastic Eastwood tank sealer. I cleaned it out the best I could, but I
could not reach the plastic pickup screen. I took a chance and put it back
together and I still have no flow unless I force it with some pressure.
I've quit for the day, but forewarned is forearmed. My sealer was in since
1990 or so and now it is junk. It was not an epoxy product as it was single
part material. maybe all the ethanol is the culprit, but I would not use a
sealer again unless I had a specific need to repair a leaking tank made of
unobtanium ( Mark Donahue coined this great word)
