This is just insane, you replaced your incorrect hose with incorrect hose... E85 or 93 octane you need submersible hose, and all of your current lines are fine for any e85 or 93 or methanol fuel. Stop making E85 clickbait please!

Have you ever considered putting two QFM-360-X motors. Each motor claims to make 1340hp and each motor is about the size of a rotor. Imagine a 2680 hp engine the size of a 13b. Granted this motor is electric but this motor literally looks like a rotor or at least that was the vibe I got when I first heard of this motor.

Ethanol causes blindness. Be careful saying people are taking shots of it because these idiots on the internet will... And blindness and retardation can be caused with as little as 10ml of this stuff. Do not do shots or drink E85. Jesus christ Wood grain alchohol is not metabolised by the body like regular spirits...

I had the opposite happen on a supra(and many other friend's cars). I used e85 safe "gates" line and it dried out to the point where it would snap like bakelite plastic, after about 3 years. Running e54 seemed to have mostly solved the problem for a minor drop in octane/cooling rating. If I were to guess, its the e85 safe 2 stroke you're running that is softening the lines. I know castor oil is hell on rubber lines(which is why they recommend silicon lines for oil injection systems).

Rob, just a word of caution on those hose clamps. I used them under the hood on my FD years ago and I started smelling fuel. When I dug into it I found that the screws had backed out some from the vibration. I've added a drop of blue loctite on the threads and hopefully that won't happen again. I'd like to see a version that has a nylock nut instead to eliminate this problem.

Never use ethanol fuel in older model vehicles including motorcycles. That crap melted ever piece of rubber in my 1980 Honda Goldwing GL1100i (fuel pump, and many parts in the 4 carbs) it also goes bad in less than 4 to 6 months clogging every needle valve you have.

Amusingly, while in University, I wrote a rather lengthy thesis paper on the development of ethanol-based fuels back in the early 1910s-20s, largely spearheaded by Ford, who saw it both as a huge possibility during prohibition (there was a lot of the equipment needed collecting dust), and as a means to increase engine power with higher compressions because gasoline at the time was hugely unstable, leading to huge problems with engine knock -- ethanol-based fuels are inherently far more stable. Eventually, DuPont won-out with Tetraethyllead, which was an 'anti-knock additive' that, unlike ethanol, could be patented and sold. Thus, we had 'leaded' gasoline for 50+ years until the public became aware that breathing vaporized lead was deemed 'pretty uncool' by doctors and unleaded stabilizers came along in the 80s. Of note, most alcohol-based fuels (if not all, at least in the US because of regulation) are denatured alcohol, meaning you SHOULD NOT drink them in any concentration or mixture.

The reasons why I dislike using E85: 1. Eats away at your fuel lines/rubber hoses & cloggs up the entire fuel system if left for a long time in a parked car 2. 30% more fuel burned which means worse gas mileage 3. Worse for the environment, they use corn to manufacture E85 which forces our entire food prices to increase over time 4. Diminishing returns for a modified daily driver E85 is a waste & is not needed, you are better off using 93+ a bottle of octane booster 5. Hardly any E85 stations in my area, you would have better luck finding diesel fuel 6. For a drag car you are better off using 110+ octane race fuel for less detonation & using a waterbox 7. E85 price might be cheap now but in a few years the government will figure out a way to raise the price even more 8. E85 has a bad track record, you can watch alot on youtube videos of performance cars having clogged fuel injector problems while using e85

We had a early FIA endorsed race fuel-cell bladder go bad with ethanol added fuel. "The lack of fuel can't be the tank or the pump, they're E fuel ready....." Famous last words ;o)

rob you need to youse special submersible fuel line for in tanks pumps regardless if you use meth or petrol as the outside of any fuel line reinforces the hose but the half outer layer will deteriorate within 6 months or less it's not designed to sit outer part in petrol or else it swells blisters often bursts open

How to make sure your rubber lines wont leak? - Use metal hard line. Some pump manufacturers even have that push fitting threaded in the pump frame, so you can replace it with sturdier stuff. Just remember: If you put metal parts; clamps, nuts, screws etc where the fuel is, You'll introduce metal particles inside your fuel system. Those particles mess up your fuel flow, kill your pumps, kill your solenoids, travel inside your combustion chamber and then mess up your hard seals, plugs and turbo fins. Hard line absolutely needs a thorough flushing before operating, but then again so does all the other options as well.

Instead of using oil on your push locks try using soap it will dry up and ensure a better lock making it just as easy to install and a lot less chance of it coming loose later

I can actually speak from my experience with 2-stroke engines, HOSE CLAMPS ARE NOT A FIX FOR THIS, over time the hose becomes more and more saturated and becomes so soft your able to pull it apart by hand, its like penne pasta almost, seriously finding a 2 stroke safe fuel line was the bane of my life for a good year😓

i just mentioned this somewhere in these comments, but your right. Its not the e85 doing this... its the castor 2 stroke oil. Use silicone line for any non synthetic 2 stroke oils.

Oetiker clamps are good on fuel lines, as long as they are sized correctly for the OD of the hose, they are one use only, they clamp pretty much round, so you don't get a corner, like you do in worm style clamps. for budget fuel lines, ''gates barricade - greensheild'' it's biofuel friendly, it shouldn't have a problem with e85
