Fuel evaporation is not, as the carb is 100% vented to atmosphere.

I'm a believer in evaporation being the dominant source of loss and significant enough to be a PITA after only sitting a day or two.

I also know the mechanical pumps have a built-in check valve.

IIRC, the stock filter at the carb inlet also has a check valve, correct?

Regardless, I think I've asked before but what specific electric pumps are used for this? I suspect I will want one.
