Thats pretty much impossible for me to do. I already have the largest bulkhead that I can get for the hole. And I can't drill it out anymore without affecting the structure of the tank.

I can maybe step up to a larger pipe ( 1 1/4" or 1 1/2"), but I don't know if it is a benifit considering the bulkhead restricts the flow.
