Default fuel surge

Hi guys,
I have a sportster i built in 1997 with sierra cosworh engine. I have standard large fuel tank. I do get a problem with fuel surge once the tank gets below a 1/3 if i accelerate hard. I was going to modify it but never got round to it and it doesn't cause too many problems. I thought about the special foam they use in race car tanks which prevents surge, the only problem would be the float would need clearance. I suppose if you haven't put fuel in the tank yet it could be fitted with baffles.

best regards Brian
