Well,
I do take exception to the comment about Bosch K-jet injection. Hot starts
were not an issue with them really as used on the BMWs, VWs and Mercedes.
But they are a full flow system returning about 10-20 gallons an hour back
to the tank. This is true of all Bosch injection up through at least '97
when I stopped working on them. The big problem with them all was starting
with the throttle open. They weren't designed for this and they would lean
out, backfire and blow the rubber induction boots off and or damage the
airflow plates.
Typically most injection systems, including turbines use some type of
pressurization and dump strategy, and many of them use a return system to
not only cool for vapor lock, but the extra fuel also cools many components
like the in tank pickup pre-pumps.
