UNSAFE aftermarket fuel lines CPE (synthetic rubber)

[@Doc_Fischer]

I agree. I have been building fuel line assemblies for years, also built plenty of hydraulic line fitting setups in the agricultural and marine industry. That CPE although rated for fuels is only good for toilet and sink hoses. It still breaks down with oils. Don’t be cheap , lives depend on it. Always go with PTFE. Good video.

Audience, Stu thanks for the safety tip. Stay safe and keep sliding✌🏼

[@HappyDayGarage]

That was exactly my experience with "fuel safe" plastic braided rubber lines. Very dangerous indeed, mine also luckily let go with fuel pressure rising up before starting and driving the very first drive of the season. Great video, man!

[@Cautela]

Every advert I've seen for CPE states to not use it with ethanol fuel. Also, Murphy gas stations regularly have ethanol-free pumps, and if you can find your local mom & pop gas station they usually have it too.

[@Sgt.Slides]

i have heard of non-ethanol gas, but i've never seen it. best thing to do is stay away from CPE.

[@WoodLox]

Remember back when I built my double line set up about 20 years ago on my 670 street avenger. Those inferior hoses almost burnt down my ride and spilled all over my intake manifold. Actually here cause someone put a soft line from the tank to the pump on my old school which choked or vapor locked and wanted to see if anyone else had similar issues.

[@Sgt.Slides]

I used a rubber "Fuel line" inside my tank as a quick repair, and never went back to fix it. It burst after about a year, luckily there's no major safety issues with the in tank line breaking.

thank you, just switched my cart from $40 earls fittings to evil energy ones on amazon after doing my due diligence and researching. evil energy fittings seem great as long as you don't mistakenly buy the CPE fittings. but yeah, just watched this and switched a whole cart to evil energy ptfe fittings from summit racing. i believe the negative reviews for the evil energy fittings are because people run CPE ones instead of PTFE ones since they're a few bucks cheaper. i would've made that mistake if i did not watch this video 👍🏾 ...application is a 96 Jeep ZJ

[@Sgt.Slides]

yeah, the cpe fittings are totally different from the ptfe ones, you cant swap them

[@snake_eyes_garage]

Thanks for the run through. I don't know much about PTFE but sounds like it is worth researching. I've tried to stick with known brand names like Continental, who says their lines are coated and won't break down with E85. But I'm sure the difference is that I haven't been running high fuel pressure. FWIW I keep the rolls stored in ziplock bags and then in a plastic tub and they've lasted for years that way.

[@Sgt.Slides]

It doesn't matter the brand. CPE is CPE, and it's not good for e85.

[@stevemelton966]

this guy is correct. good video.

[@Sgt.Slides]

would you believe folks still want to argue with me!!! Won't be my car burning down. I tried to help folks.

This exact failure happened to our mutual friend Ethan.

[@vincentiiramirez8185]

What about copper tube as fuel line do you think it will do better?

[@joshscott8678]

So is he saying fuel lines arent safe for fuel?

[@RogerAlcon]

Do you recommend CPE for oil Motor? I need to put a CPE hose for my motorcycle oil Cooler then I have been thinking about using this.

[@Sgt.Slides]

I've been using the CPE hose on my oil lines for years, No issue.

[@1996English]

But is it safe for coolant lines? I'd never mess with fuel lines, I will always leave that OEM.

[@Sgt.Slides]

OEM fuel lines aren't always an option when you're swapping an engine, and even if you get the correct adapters to connect to the OEM fuel line, you're still going to have to make a section to go to your new fuel rail. There's a correct way to do things.

[@Sgt.Slides]

and coolant lines do not contain ethanol, so you're fine using this stuff for coolant, oil, or whatever fluid runs thru, just not gasoline/e85.

[@heith85]

I feel like the generic rubber hose you were implying carb fuel line. Which yes I agree don't use it on fuel injection but fuel injection is completely fine and doesn't require any over priced AN adaptors to run it

[@Sgt.Slides]

Rubber hose + modern fuel is a no go, even if you are using a carb.

[@heith85]

@@Sgt.Slides that's a fairly ignorant statement. Check out Eaton's or gates product line. They have hose's rated for e85. It's the same hose material used at the pumps at the gas station.....

[@daves485]

@@Sgt.Slides Gates says their rubber hoses are ethanol compatible. I think it should be fine for a carburetor. I changed all the rubber hoses including the gas tank fill tube after being scared to death from reading comments like this. I have to admit everything looked fine after 7 years. I even changed the fuel pump, took it apart and even the diaphragm looks good. Trust me this wasn’t an easy task on a 1951 bel air with a V8

[@Sgt.Slides]

@@daves485 These aren't Eaton or Gates hoses. I don't know anything about their product, or why you are telling me about them. If you like Eaton & Gates, Use them.

[@BuddyTheWolfYT]

I got gates barricade to replace the fuel lines in my 1981 vanagon
