the only reason i changed out the pump to the 5gpm they sell is i was maxing my psi out with the 4gpm when i would use the 1gal/k tips. didnt have much going back to the tank. so now i have the 5gpm pump on there and more going back to the tank and i am not maxed out on the psi. with the other pump i needed 28psi to get the 1gal/k mark and that was all the pump had this one as more if i need it..
The Internet lets you be anything you wannabe except smart. Your stupidity will always come out.
