And all of that for nothing! Pulled the pumps and the heat shrink butt connectors I used look great after 2 years, better than the ones that came with the pumps did before I had to replace them. Zero degradation, and were hard. So not dissolving while sitting in e85. Threw the pumps back in, fueled it back up (drained with my relay and hose off the rails). At least now I know I don't have to worry about it.
