Yep - the AFBs are prone to fuel bowl heat transference, and the under hood space is not huge in our Oz Valiants, so that doesn't help and means we cant run big spacers.
Holleys don't seem to have the same issue..but at $5.00 a gallon a Carter/Eddie is a smart investment for a street driven car. ;)
Its ambient heat from the ashpalt and traffic combined with long idle periods at the stop lights or in the staging lanes - so we block the heat cross over, run a return line and a shroud with electric fans or clutch fans.
Physixx - thanks for the offer, I'll find someone on this side of the pacific:-D ;)
