fuel from pump to carb question

[sactoC10]

Have any of you transplanted the line from the fuel pump to the carb with a partial rubber fuel hose or something different than the stock metal line?

I thought I'd resolved my possible "vapor lock" problem, but yesterday the wicked thing returned. I was about 2mi from home after driving around town with the kids (plenty of time for things to get real hot) and old yeller started bucking on me, sort of wanting to stall...but not quite stalling completely.

My wonderful 9 year old daughter said, "Stop doing that daddy!" To which I said, "I'm not doing that." And she replied, "I see your foot dad, stop." I then explained that I was trying to keep the darn thing FROM dying. (part one)

Then, about 3/4 mile from home on a busy 5 lane road, I did not win the battle, truck stalled and we rested in the "suicide lane" for a minute. Then I said, "hold on kids" when it fired back up and I threw it into drive with the RPM's up there. Figured I could coast most of the way from there with a BIG wheel spinnig screech back into traffic if it died again, but fortunately we made it right into the driveway. (part two)

My fuel line is up against the water hose that exits on that same side of the engine. I am thinking (guessing) that this may be the area where the fuel is getting REALLY hot before reaching the carb when the engine and water through that hose are very hot...NO?

Little help...please!
