Specialty PVC PIPE 2 inside 1 Pipe

[Gold3nku5h]

I was wondering if anyone knows of a similar part, or has ever seen or heard of one. I have two holes drilled in the bottom of my tank, one on the land side, one on the water side. I need two pipes (Water pump, fogger) to go through the single hole on one side, if looking at an aerial view of the pipe, it would be (OO) if the two ( ) were the outer wall of the pipe. I have a crappy drawing, i just bought a macbook pro, and it didnt have a paint program, so with an hour of time, this is pretty much all i came up with.... ah, i guess i have to set up another flickr account. but it would be a pipe with two interior pipes and on the ends it would split into a Y, so that one pipe leads to the water pump, and the other, to the fogger, just through a single hole. Does this make sense?!??

You could run two supply lines Up through a Single pipe.

Are you trying to use the same water in a Fogger?

Silicone the hell out of it?
You could find a cap that fits the outer pipe (or is it just a hole?) to seal it completely, then drill two perfectly sized holes in the cap to match the two hoses that you intend to pass through, pass them and silicone it well.
