Hmm, yes I have read about how to mod SSPBs before. I have plugged the pump handle already; as for the barrel, I thought if I do it, I should at least get a stock picture first since it won't fit so nicely after that. The aluminum pipe will fit nicely based on my measurements. For anyone trying to do this mod, keep in mind you can't just set in the sspb. It is slightly too tall, which means you have to separate the pump from the barrel, and shorten that connection slightly. On a last note, I have never seen that tank expansion mod, I need to try that.

You have to carve out a great deal of excess.
