Dual Walbro 400 failure on E85

Wanted to share both my 400's died in under a year on E85. These were the non-e85 pumps and well both my pumps crapped out so lesson learned. I tested them outside of the tank they run for about 30 second before coming to a stop. Really strange they failed together but if I had to guess one likely went out and the other soon followed.

My old walbro's 255s ran for over 4 years with no issues, they were also not e85 rated however worked fine.

Wanted to share this info. Make sure you run the new e85 approved pumps.
