I was reading about how the injectors are designed to handle vaporized fuel to avoid vapor lock. Something about a channel that allows the heavier liquid fuel to sink, forcing the vapor up a channel and back into the return line. Seems as long as it doesn't get heat soaked, this wouldn't be a problem. I'm looking for TBI parts myself right now. Trying to source from craigslist, paper and friends. Looking tommorrow at junkyards. Good luck with yours. Jim
