How To Choose And Use Hardline

With all the choices and differences in tubing materials today, choosing the correct hardline can seem daunting. Each material has its own pros and cons so you’ll need to consider the specific application or vehicle system that you plan to use it on, before making a purchase. Earl’s carries a wide selection of tubing in a variety of materials and sizes for use in most any automotive system. Follow along while I break down these tubing designs and give you a better idea of their benefits.

what ever happened to good competent apple pie teachers like this? easy to listen to. good information. and concise.

[MrAuzzie]

I love this video. I spent HOURS compiling a spreadsheet months back with all the information contained here. I know it was glossed over here, but I would love to see a video about single flare vs double flare vs bubble flare. How to identify 37 degree from 45 degree by sight. What is reusable between tube sleeves/45 degree double flares/ compression fittings. Can I mix and match a 37 degree aluminum fitting and a 37 degree steel fitting. Corrosion inside the lines (ethanol, methanol, oil, water ect). When to use crimped lines vs when to use homemade lines.

Again thanks for the amazing information. I wish this video had been out sooner.

You guys have awesome informative info. Thanks for this.

Is there a downside to using Easy-Form Tubing as fuel lines? I feel like it's a bit too good to be true, but it would be a Godsend for replacing the fuel lines on a C3 corvette.

Great video at last someone has compared line materials and flaring tools 🛠

[jeffreycoppensjr]

That was a ton of great information! Thank you!

[robertmccully]

I need to run hose/tube on hotrod from the engine driven air compressor to the air dyer this line will get quite warm 200 degrees and need to run about 6 feet and support 120 psi what would you suggest I'm think earls steel line needs to be 1/2 or 5/8

[BasedBidoof]

time to ponder my decision to buy NPT fittings before learning about AN fittings...

[myaz]

Hi earl's.. Which is most suitable for my oil coolant sistem, my coolant also had pressure and temperature reaching 120c - 140c

[Kiret]

why do you not recommend using aluminium line for brake system?

[robertclymer]

Need some feedback please. Can the hard line from tank be replaced with neoprene hose from tank to carb? My hard line vibrates from elect pump and is so loud. Thanks much.

[RyanNelly]

What type of metal fitting could and should (with concerns of corrosion or electrolysis) be used to hardline to an aluminum radiator?

[NateDogg]

Are there any problems with using the copper/nickel tubing with E85 fuel?

[noksu_krx]

Which lines do you guys recommend for running e85? Please i don't w as not to use ptfe rubber.

[davidcalkins]

For a stainless steel line when should I add the 37 degree flair and when should use the a ferrel and the hard line adapter

[jamesgiguere]

Here is a question: Does the height of the fuel line you run, in relation to the tank and fuel pump, mater? To save hassle I'd like to run my new lines over the inner fender to the mechanical fuel pump in my 73 Torino. This rout will bring them over the height of the fuel pump. and back down to it. Does that even matter? Please help.

What the tool being used at 2:23 to make that bubble? Part #?

[capri]

but max diameter is 1/2 for the aluminum fuel line if you made a 5/8 / 10an line I would gladly change over but sadly you dont
