So, what are the symptoms of bad/old fuel? If the car started, what would it sound like?

I am having some troubles.

Thanks in advance!

Maybe sound like it has a "miss". Fuel not burning in the cylinders, Rough idle? I helped a guy last weekend pick up a 66 Chevy truck - straight six. The truck has been sitting for 6 years. When it was parked, it had a new fuel pump & dist. The first time we cranked it over, it shot gas out around the fitting on the carb. We fixed that, pured a little fresh gas in the carb just trying to see if it would fire. 2 cranks and it started right up. It ran pretty rough and sounded like it had a bad miss. He drove it to his house about 10 miles away on that crappy gas. We drained the tank and this stuff was dark brown and stunk bad.

And a noticable strong old fuel smell at the gas cap.
Old gas has a very different strong smell.

Thanks for the help.

I have the rough-running going on. I actually have to keep the pedal down or the car will immediately die at idle.

I put in 3 gallons of fresh fuel, but no difference. Then I drained off a gallong and changed the fuel filter - still no change.

The gas I drained does not smell too bad, but it is mixed with that fresh fuel now.

I guess it's time to drain it all out, huh?

Thanks again-

Bad gas could be old gas but it could also be water in the gas. Symptoms would be stalling, rough operation, and hard starting.

Thanks, Dennis. I get the stalling and rough operations, but she starts up every time (so far).

I guess I shouldn't risk filling her all the way up in case it still doesn't work. I think there are only about 8 or 9 gallons in there total.

I'm still hoping for time over the long weekend to figure this one out. I guess I need a few empty gas cans and a place to drain them...

Have you tried a can of dry gas? If it's a water problem it may clear it up enough for you to burn thru the bad tank! You have a CARQUEST store in your area they should have a couple of pro quality brands to chose from.

I'll check it out. Thanks!

yeah dry gas and or octain booster

Seafoam work wonders. Not only does it clean the fuel system it also works as a gas dryer. Thats the first thing I'd try at least. Worth the 6 bucks to find out and you'll have enough left over to de-carbon the engine while your at it. Have fun.
