help on surge tank

[fishme]

I'm planning to add a surge tank and do need some help. Anyone here has one? Actually, my question is where should I drill for the air relief hole?

I will go to AG and Atlantis to check out theirs again this weekend.

Thanks,

Thanks Mr Ugly.

Also, just found this link, it includes many types of DYI surge devices
