Replacement pump head tubing Dos
Update:
Pump is running perfectly with the new tubing. It is still a little bit more noisy than stock, but barely noticeable. I was looking around on the McMaster site again, and I think "durable Tygon" 52035K may also be a good option. It's rated the same as far as compatibility, and it comes in 1/16" and 1/32" wall thickness. If it's slightly softer than the Norprene, the same 1/4" od, 1/16" id (1/16" wall thickness) should work great. It's a bit more expensive ~$5 per foot, but I think I may order to compare. Will post the results.
