I got my feed and returm lines. They are ss braided teflon no rubber, need a way to clamp it without it leaking!? Help!!

Clamp to what?
The Teflon hose uses special AN fittings with a ferrule much like is used in copper tube compression fittings.

I doubt it could be effectively clamped like the rubber lined hose can.

That said, with the pressures we run in the FI systems, you should be using the proper fittings.

What Ron said.
A quik look at places, such as Summit, will show U what's needed.

Also, to figure out how to install it, go to youtube and in the search bar type Summit braided line install. That's how I learned, it's really simple.

generally speaking you do not clamp such hose, you must use proper fittings.

Teflon SS is an odd choice for fuel line. Last time I used the teflon stuff it was for a custom power steering line that saw 1000+psi.

Proper fittings must be used.

Teflon should not be used for PAS as it isnt rated high enough for the potential pressures involved. Yes it usually works and is ok, but it still is not the correct choice.

Teflon is insisted on by most world motorsport bodies where fuel line runs inside the cabin. And Teflon is essential to prevent fuel smell inside the cabin again where routing is inside.

Plus Teflon is safe for all fuel types. Nitrile rubber is not.

But it should also be used with the correct fittings. Clamping this style of hose is not the correct way although in some cases it might just work. Obviously any pressure ratings would be very low with a clamped hose.

Well that makes sense. As for the power steering. The line I bought said @-6AN was rated for 2500psi max NOT burst. That line has served me well since 2005 with many auto x runs. It lasted where the pump did not. :-)

I would try to get the same brand fittings as your lines. Small differences from company to company can mean a pain in your **** trying to assemble and ensure leak free operation.

Companies like Earls have specific re-enforced hydraulic hose for PAS lines and steel fittings, even they do not recommend normal Teflon or even alloy fittings.

That said, A friend even used a normal brass compression fitting on a steel PAS hardline and it never gave any trouble many years on. That is rated nowhere near 3 figures either !

I know on my own car I used their proper PAS lines. Why risk it when PAS is extremely flammable, and Ive seen a few cars go up in smoke because of dodgy PAS lines.

And as Sarg says, try not to mix and match across different brands. There can be small differences in sizing, and that's all that is needed for a leak.

Speaking from experience, an engine fire can happen quickly when using the wrong line for the application.

Yup! Had a buddy have his go up from a minor turbo oil feed line spray. Mine almost went up whe. I was told I could use a type of hose not rated for ps fluid pressures. Lessons learned.

Are you talking about clamps to attach it to your frame rails?

If you are something like these would work.

Also when you use braided stainless like make sure you keep it well clear of any other lines, hoses, or wires. Vibrations can cause it to cut thru or other wise damage them.

Good luck

I'm using ot for my oil feed akd return lines guys. Not for fuel? Did I buy the wrong lines?

stevieturbo

Teflon is fine for almost all liquids. You did not buy wrong

What fittings do I need then?

What brand did you buy? If you know contact the manufacturer for guidance. I you are not sure go to several different manufacturers web site and see what is available. Teflon fuel lines are better than rubber, methanol is very corrosive to rubber products. Almost all fuel these days has methanol in it. The Teflon will last as long as you own the car.

Manufacturers;
Goodridge
Fragola
Russell
Aeroquip

There might be more but that's all I can think of right know.

98WhiteLsX

I think both are eaton branded.

We aren't psychic. What are you trying to do ! What exactly do you have ?

You need fittings specific to each job in hand
