Was going to run the Super today to see what the fuel problem is. But after I primed the lines with the starter, I noticed the fuel is discolored. Dark yellow tint to it. Pulling the cap and smelling the tank, it has maybe a slight sweet smell to it. Not nearly as bad as it was after sitting for many years, but I worry about the quality of the fuel in there now. The last thing I want to do it run the car on degraded gas, then end up with gummed up/stuck valves. This engine has maybe 80 miles on it since rebuild.

Hard to say how old the fuel is in the tank. No idea how much was in there when I brought the car to my house after rebuild. I've put fresh non-ethanol fuel in several times after driving for testing. Probably 15 gallons at least, over the last 1-2 years. 5 gallons at a time usually. I put fuel stabilizer on it during the winter.

What do you think? Drain the tank and start fresh?

The appearance and the odor you describe indicate bad fuel. I would NOT run the car on that, even for a short time. Find a safe way to drain the tank and dispose of the old, soured gas and clean the filter**. I'd put at least 5 gallons of fresh gas in the tank before attempting to run the car. It would be advisable to flush the fuel line and pump and drain the carburetor.

***It looks like the upper metal part of your fuel filter is distorted by having been over- tightened.
I'd replace that to avoid the possibility of a pressurized fuel leak under the hood, which could lead to a fiery disaster.

Those are my thoughts also. Drain the fuel, flush the lines. The carb is dry.

I see what you mean by the bent metal. That is the integrated fuel bowl on the fuel pump. It is on the suction side, so no pressure. The fuel pump is also located at the very bottom of the engine. Stock Super 8 fuel pump. It doesn't leak at all, but I'll have to get a better look at it to see what the issue is with the way the fuel bowl is sitting. I do remember when rebuilding the pump that the casting in that location was damaged. Some sort of a crack/missing chunk on the outer rim of the fuel bowl seat. Probably not repairable and these pumps are hard to find.

If it leaks air in it will cause fuel delivery issues.

This is true. The gasket above the bowl "should" seal the glass, but I'll have to check.

You should just be able to get a siphon pump and use that to drain the tank. If you disconnect the line on both sides of the fuel pump and drain the carb bowl then the only thing left will be the gas in the carb itself.

That can also be drained though it tends to evaporate fairly fast as well, depending on the model of carburetor.

I kept the old annoying super loud electric fuel pump that Jackard came with, which works great as a transfer pump.

Use that old fuel in your lawnmower or snowblower.

I unfortunately removed the electric fuel pump from the car a couple years back. So I pumped about 10 gallons worth by hand tonight. Both of my spare fuel containers are full now (both were previously contaminated with bad fuel from my brother in law's 200). I'll need to dispose of those before I can drain the rest.

Funny you should mention the lawnmower. I used contaminated fuel from the previously mentioned 200 in my lawnmower and it really messed it up. It's a large rider, and I went through at least 6 fuel filters almost immediately. Gummed up the carb and such too. It'll need a rebuild eventually. So I would be cautious about using bad fuel in something else. It was actually new fuel that was poured in a bad tank....but there was enough varnish and crap that got dissolved in a short time that it ruined the new fuel almost immediately.

Rotten fuel can quickly damage any kind of internal combustion engine. I would NOT use it in any gasoline engine or any gasoline appliance, such as a camp stove or lantern, and I would not store it in any metal gasoline can.

Since it hasn't lost its oil and grease-dissolving properties, I use it to clean my tools.
