E85 vs AI

I posted this is my other thread about injector sizing requirement, but I figure I would post it here as well.
Another CON for e85 is its stickiness and that leads to clinging onto trash. My buddy just pulled his pumps on his GTR because his pumps weren't turning on. He found the pumps had overdrawn due to clogged filters/socks. The wires actually got hot enough and melted the surrounding padding around the wiring and toasted the wires(there was a fuse issue as well and why they overdrew, but the fuse would have blown due to the filters being clogged and the pumps continuously trying to pump fuel).. E85 is very sticky and clings to trash/debris far more than gasoline, see pic below, this is only with 2000 miles on the system running e85... I know the positives are huge running e85, but this is a pretty big negative IMO. I would advise anyone who's running e85 to check and probably replace your filters often/yearly depending on how often you drive the car.
Just my 2 cents, I'm no pro, just a garage monkey...

It is not that E85 is sticky, it isn't. Ethanol (and E85) is a wonderful cleaning agent and very astringent. That is also why certain materials need to be avoided when using E85.
Because of the increased flow requirements due to the lower energy density of the fuel, everything from the filter socks to the injectors needs to be upsized accordingly.

In comparison to gasoline it is sticky/tacky, which means dirt/trash/debris clings to it easier...to "me" that means more opportunity for debris to contaminate the fuel from time it's made to time it makes it to your pump/tank compared to gasoline. On top of that, any debris that is in your tank tends to settle with gasoline, with e85 that debris will cling to it more often than settle and find its way to the filter/sock and eventually clog it. Which is why anyone running e85 daily or often should check and/or replace their filters/socks.
Trust me, I'm all for e85. This is just a con that no one usually wants to talk about or know about it seems.
