2. Took off the air cleaner and snorkel hose and looked into the carb while opening the throttle and noticed that gas was not reaching it.
3. Disconnected the distributor bat cable and then disconnected the fuel line and saw that gas was coming out when the starter motor was operated.
4. Removed and replaced the clogged fuel filter.
5. Replaced air cleaner and all hoses.
The car seems to run fine now, except for the fact that the SES light trips after startup. Anyone have any idea why this could happen?
Thanks,
Alex

with this engine I'm guessing its the O2 sensor. I would get the failure code and post this here for what is wrong.
the reason I say it may be the O2 is , this would cause the engine to run very good with the O2 not correct in operation .
I would replace the fuel filter after a few thousand miles . these metal fuel tanks with alcohol are a big problem with rust generation. If you have the old filter use a magnet to see if it is rust .
add a few ounces of marvel mystery oil to each fill up, or 1-2 ounces per 10gallons of fuel. this will clean up and protect from future tank corrosion.
