Shane, I did up grade to a Shurflow Revolution 4008 pump rated for 55 pounds. The pressure tank was bought from Amazon and was a 2 gallon tank (I set the tank bladder pressure at #15 it is adjustable directions included). It was a lot cheaper on Amazon than Home Depot although HD did stock them. I did some browsing till I found the tank I wanted with free shipping and it was here in 2-3 days. I also bought the Shurflow pump on Amazon with free shipping. When I installed the new pump I placed a rubber isolation pad under it and wow you can barely hear it run.
