Re: Vapor lock 1 and 2
When I first started my long road trips I was curious so kept track of mpg just to see. It seemed low at 11+ not quite 12 mpg. Posted on the barn and got responses that was way low as others were getting 15-17. I had, a few years previous, put in larger carb jets to reduce my engine temperature and ping which worked but I had the thought that it also reduced my mpg. So, I put the smaller ones back in and mpg jumped to almost 15 mpg.
I don't keep track any more but it does make some difference when I'm driving well over 1,000 miles per month. More on gas mileage here; http://www.fordbarn.com/forum/showthread.php?t=99762

Re: Vapor lock 1 and 2
That's where you need the gauge in the fuel line, T ed into the pump to carb fuel line.
Read it cold when the engine is started and it gets lower as the fuel pump get hotter. !25 degrees on the top of the pump and below 1.5 lbs fuel pressure and the trouble starts. G.M.
