[DML] Re: New Gas Blends and older cars

Vapor lock has not been a problem for a half century. Dual diaphragm
fuel pumps introduced in the 1960's eliminated the last vestiges of it.

Of course the likes of Lou Costa, Kyle Franklin, and myself have
absolutely no problems because our fuel pumps are located in the tank
(electric). Vapor lock was a suction problem, not a pushing problem.
That's why I roll my eyes every time a K-Jet owner claims his car is
vapor locked. If us carbureted owners can push air out of the way with
4-6 PSI, a K-Jet owner is certainly able to do so with 75-80 PSI.

Think of it this way: Our fuel system is no different in principle
than household plumbing. When was the last time anyone shut the water
off for a repair, then couldn't get a faucet to work later because air
had been introduced into the system? Water pressure forces the air
out, then here comes the liquid. And that's at a mere 28 PSI or so.

Please use accurate information when disparaging carburetion.
