[DML] Re: Warm Start Issue (David McKeen)

["content22207" <brobertson@xxxxxxxxxxxx>]

I beg to differ:

The DeLorean uses a high pressure fuel pump in a continuous loop fuel
system. Vapor lock should not be an issue.

Vapor lock was an OCCASIONAL problem for carbureted fuel delivery
systems, caused by:
- Low PSI fuel pump (4-6 PSI)
- One way fuel delivery (with the carb at the top)
- Location of the carb (in the middle of hot V shaped engines)
- Some unfortunate carburetor designs
- High altitudes
- Less sophisticated gasoline formulations of the day (MBTE wasn't
introduced until the 1970's)

If a DeLorean loses rest pressure, whatever gasoline vaporizes in the
lines should be no match for an 80 PSI fuel pump, pushed right back
into the tank.
