Thanks for the replies. I am considering going to the return line setup. Ron
Driving on the street w/ junk pump gas, I'd strongly recommend it!

I first ran into this problem a couple years ago. Driving home from work (65 mph on the highway mostly) I stopped at the gas station, then the car was a bear to refire. Flooding out, would run briefly then die, blah blah blah. Had that happen a couple of times after that before I broke down and spent the money on a bigger pump, regulator, lines, etc. It was definitely worth the money.
Only time I've had an issue w/ it recently was during the True Street race at Rockingham a few weeks ago. We had to do a 10 mile drive, then pull into the lanes w/ NO cool down time and do 3 back to back hot laps down the 1/4 mile. I didn't have enough fuel in the tank so it started recirculating hot fuel...it used more than I anticipated. By my last pass it almost died coming out the water box from the fuel being so hot and trying to vapor-lock. It ran 3 dead on 10.01 at 135 mph passes w/ a broken torque converter and won the class, so I wasn't too upset, lol.

I have this exact same problem, and it started as soon as the winter blend gas went away.
the RVP of winter blend gasoline is higher that that of summer to aid in vaporization, winter blend would be much more likely to have vapor locking and boiling problems.
just curious how many if any of the guys having these types of problems are running some type of insulator under the carb?

I have a 1" wood spacer under the carb.
