Great Results So Far with Vapor Purge Line

I plumbed in a return line from the fuel pump output back to the tank. It runs through a valve that is just *barely* cracked.
So far so good - fuel pressure is rock steady
What used to happen after a long time running on a hot day is the fuel pressure would get erratic, dropping to 0 or close and bouncing back up to 4. On rare occasion fuel would quit feeding altogether
One odd side effect is the engine is a lot easier to start. I think the carb primes a lot faster now.
