120g AGA MegaFlow Bulkhead size?

[barbra]

Hello all,

Last night the outflow on my tank burst. Most of it fell into the sump where it was returned as it normally would have been, but there was a great deal of splashing and spillage, what a mess.

At any rate, the bulkhead that is attached to the tank is fine, but the hose barb fitting with the hex at the top that is connected to it is hopelessly damaged. I bought this tank used and it appears that it had been modified somehow and that modification has failed. I need to only replace the fitting that attaches to the bulkhead, but without dismantling the tank, which I didn't have time to do this morning before work, I don't really know what size I am dealing with or what part to buy. I know I want them on order today though.

I looked at the AGA MegaFlow overflow kits and the parts I want are clearly pictured, but they don't tell you the specifics on each part. I don't want to spend $50 (plus overnight shipping) on an entire new kit, can someone point me in the direction of the components I have described? Savko doesn't seem to have the parts, but I may have not looked in the right place....

Thanks
