I have had the belt driven pump from Glacier for over 5 years now. Works flawlessly except that for the last year or so it leaks a few drops when I park the truck. I did have to replace the inline regulator that comes with his kit with a real one. The kit comes with a cheap junk one that isn't dependable for long term use, it's a racing version.

But overall, I hope to never go back to an electric pump again.
