vapor lock?

I had the GTS out and the old dude was hustling down the freeway, I get off then boom nothing.

I popped the hood, and pulled the air cleaner, and I had one heck of a venting off the carb vents on the edelbrock. It was pretty warm today but just surprised.

I had issues earlier with it seeming like it was starting hard and loaded up a bit.

I let sit on the shoulder of the offramp for 5-10 minutes, put the clutch in and boom fired up with my foot to the floor...driving home it was giving me a couple indicators it was doing this again but I limped her home and no further issues.

Bit puzzled but assumed just hot out and that's why.

 I know what you are dealing with . With living in central Fl. and/or todays fuel quality had a lot to do with the vapor lock issues I was experiencing. I firmly believe that todays fuel will boil more readily when introduced to a vacuum system, especially when heat is involved(I once tried non-ethanol fuel, it made a big difference in vapor lock issues and in my wideband AFR readings). Having a mechanical fuel pump magnifies this, the fuel pump itself gets hot just from being mounted on the engine and the fuel receives additional heat just by introducing it to a vacuum situation(fuel being pulled to the engine). I tried an Edelbrock 1726 FP since I was running out of fuel when at operating temp and/or WOT, no help. I have done a myriad of things to finally solve my vapor lock issues. The biggest helpers were a "valley pan" gasket with blocked heat crossovers(reduced boiling fuel in carb fuel bowls), removing the mechanical fuel pump and installing a Carter P4600HP electric fuel pump near the tank and installing an orifice regulated fuel return back to tank to keep the fuel pump from "dead heading" at the carb. These, along with a couple other things, helped in totally eliminating my vapor lock issues for good. Hope this helps. Todd
