When you weigh them out don't forget the "I" word in the carb column...
with F/I you won't get ICE so things are a tad simpler w/o carb heat.

The discussion carb vs injection prompts me to add this tidbit..I
recently had an engine failure
due to vapor lock(I think ) It was a gravity feed system to a carb..Very
high ambient..low level
in tank. I have added a fuel pump with pressure gage from Wicks...about
5/6 psi.Also
a blast tube on the gasolator. The fuel line had fire sleeve and a
heat shield on the gasolator.
For what its worth !!   Charles in south Mississippi.


Do you have any drawings of the system or photographs?
Vapor lock is highly configuration dependent.
