Also been looking at a fuel cooler:

As well as possibly the Aeromotive controller:

Reason being that the A1000 flows a lot of volume at idle thru the return. Seems from what I have read that can lead to some fuel heating / vapor lock issues especially if the regulator is mounted up by the carb. Reducing the volume at idle and adding a cooler seems to help big time.
Trying to figure out if that is overkill at my HP level or not. Or simply good insurance so I'm not stranded out in the boonies somewhere with vapor lock.
