I actually am running a similar set up. I bought that exact pump kit at pepboys for $30. I ran a search on ebay, and found a 2 1/4 acrylic tube, flared end for comfort and a decal ruler on it for 19.95 with free shipping, i think the seller was gravityworksbest. The whole set up works with 1/4 inch tubing connecting the pump to the tube.
