Hi Michael -
Actually, my feeling is the problem is often caused further back with
vaporization occurring around the fuel pump when the car sits and heat from
the exhaust floats up to the pump when the car is still. Wrapping the
pipes under the fuel pump with some header wrap seems to really help (or
maybe wrapping the fuel pump with header wrap).
Another simple solution revolves around the process of fuel feed around the
carbs - A90 owners always zip tie a long piece of wood along the fuel feed
pipe under the front carb and that seems to eliminate the vaporization
problems. You may try another piece of wood on the cross feed between the
carbs. Might be a simple test to check if that works, and if so maybe the
solution is just putting some wood pieces on the outside of the fuel
line(s).
Best Regards,
Alan
