I ended up going with 1 1/2" spa flex but this stuff might as well be iron on the 1 foot length scale. I think I'm going to have to replumb it with another option.
Spa Flex is much to hard to use isolating a pump, do yourself a favor and order a short length of silicone tubing from BRS and be done with it!

PS: Use about a ten inch length of the silicone for best results.
