Hi,
Just a thought. A friend once had a Reliant Scimitar fitted with a Rover
(Buick) V8 and a Holley carb. This would suffer vapour lock in the carb
through heat soak on hot days in the UK. We fixed up a PC case fan (12 volt,
about 3" diameter), with a bit of round trunking to blow air onto the carb.
Worked via a switched, permanent live, this did the trick ,every time.
