[@kyleaudio]

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.

[@Walaboro]

i wanna bring it up again, but for rob to take on those guys and have em work on his cars and learn with him is a not only smart for him, probably saved him thousands and thousands of dollars in labour to hire out a proffesional, but good on him those guys are getting a super rare opportunity to learn skills very have hopefully they can make something out of it in the future, a shop or making parts whatever but kudos!

[@BroomysGarage]

The intank fuel hose failed because you have to use specific grade hose for use when submersed in fuel. See this video kzbin.info/www/bejne/npeoZqaogNqad9k has nothing to do with e85. Normal rubber hose will destroy and turn soft in normal ‘gas’ as well

[@TommyG_0311]

I distinctly remember an earlier episode of the 3 rotor where Able specifically told you not to use push fittings 🤣

[@PhilTheGeek]

You're absolutely right. Fuel pressure sensor is a must. And if it's a return system with vacuum/boost compensation set up the the ECU with over/under differential pressure protection. e.g if it's a 3 bar pressure regulator then the differential pressure (fuel pressure - manifold pressure) should stay at 3 bar. If it deviates from this by more than about 20% then cut the throttle/rev limit/turn off.

[@deciplesteve]

At work, we have a GTI that has been upgraded to an IROZ fuel system for E85, and we used push-to-connect AN fittings like yours and we had to clamp every single one of them or they would blow off. FWIW, we were told by Vibrant that those should only be used for return and the pressure side should be PTFE.

[@zfreak2808]

I used a bench vice for all my polyurethane bushings. Works as good as a press and is good for more than just pressing bushings in.

[@jpabon18]

[@oikkuoek]

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.

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).

[@prkidd23tc]

Rob Dahm’s R&D channel. Very fitting.

[@ralliartfanevoix]

Those clamps are the best. I use those on all the small coolant lines on my RX-8, in lieu of the spring clamps. I plan on going through my cooling system when I upgrade to an aluminium radiator to worm drive clamps (Jubilee Clamps) on the bigger hoses, with those nut and bolt type ones on the smaller hoses, because they give a much stronger grip, and there won't be any swearing at it if the tool slips off, like you do with spring clamps. Also, it's impossible to send a nut and bolt clamp to space if you remove it from the hose and release the tool, unlike a spring type.

Btw, when I converted my 709 whp EJ8 B series turbo Civic coupe to E85 I replaced the metal fuel lines with nickel copper and I used all ethanol safe AN hoses and fittings. I have Grams 2200cc injectors and a Skunk2 composite fuel rail. You HAVE to use ethanol safe components in your entire fuel system before converting to E85 or higher.

[@aserta]

There's an even better variant than hoses. Custom made fascias for the pump and the pump housing (the cradle/tank assy etc) that are one piece of billet aluminium. All you have to do is find a pump that has removable internals (or decrimp the pump's fascia and make a new fitting piece). Then you're done with hoses and with fittings and all that crap. Straight passage from the pump to the outside of the tank. You have a CNC so this is a two days project.

to stop squeaky bushings use some grease and a very thin winding of PTFE tape, just stops the squeak and you won't have to re grease easier to press in than hammer, also wind the PTFE tape like a spiral down the metal collar

[@malachidunlap525]

Rob I use all steel braided lines so I don’t have corroding problems but we use e85 for not only gas but we clean stuff with it like I had some old pistons and I left them in e85 over night and in the morning the grime practically wiped off

[@nortiousmaximus940]

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

[@CygnusRising]

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.
