Braided steel fuel hose?
 

I got my car together this week. Went to start it yesterday and the braided steel lines from the pump sprung a leak.
This is the second time I have had it happen. I changed to push-loc in the section where it happened before. Now I'm changing the remaining section to the push-loc. I still have a short section of -10AN from the cell to the pump. Should I change that?
Does the stainless line fail frequently or is it just a fluke? This is the second time.

Art, I have never seen that! Is it leaking where the fitting in installed? Or just a leak in the middle of the hose?

Middle of the hose both times. I cut the damaged section out and jury-rig connected it. It was good enough to start the car. But I'll replace it before I race.

The hose is neoprene ? the protective cover is stainless steel . I have a premade hose that I bought last year from one of the big companys that sells mail order [store brand] and there are ends of the braiding sticking out which will puncture your fingers. I imagine if I took it apart there are loose ends sticking in that would damage the hose . Anyways the Quality is a far cry from the army surplus braided steel hose I'm used to using.---Trevor

The rubber inside the braid dries out and cracks. I had a pair of premade carb lines that leaked all over after sitting one winter too many. I suspect the quality has gone down now and the fuels we use are harder on everything. Reminds me to check all my hose this spring.

Art: It seems like we are continuously replacing a fuel line in something!
I would estimate the life of our Russell Stuff to be 3 to 5 years on the Average.
If we were better about trailing every drop out of Fuel System in Winter we might have better luck. The longer it sits the more problem it seems to be.
We fired Jr's Wagon Start of last year and it was a sprinkler. We will see
how many have gone bad this winter.

Art I tossed my braided fuel line from my car last year. There was no visible leaks but you could smell fuel vapors seeping thru all over smelled the garage up constantly. Garage stink went away w no fuel line on car anymore.
Don't know about the new lines as I have not decided what to use this time yet.
Are there any new alternatives for gasolene besides aluminum?

Teflon (PTFE) stainless braided.

While I have not used this brand before, I'm checking on it this week. I saw this in Car Craft under new speed parts. www.techafx.com or 877-355-0137.
It's a PTFE hose that has a black nylon outer over a stainless steel braid with a PTFE core (I believe that is teflon?). Car Craft said it would last "for the life of your ride". Also said it would cure the gas smell in the garage.
I know from experience that if my car has been sitting around for 1 year plus, I can count on replacing most of the braided / rubber core lines. One time it looked like the fire sprinklers in a building went off!

Yes PTFE= Teflon
Some manufacturers flaunt it as being something new. Its been around forever in industrial applications. Aeroquip has had it for as long as I can remember in their industrial line. You could probably pick some up at your local hydraulics shop. Just tell them you are after Teflon steel braid and they will probably be able to help you
It is far superior to synthetic rubber hose. Has incredible chemical and heat resistance. I think the #8 I use is rated at 800psi at 600 degrees. It’s smaller OD and lighter than rubber braided hose of the same ID. It has lots of advantages the only disadvantage that comes to mind is that it is not as flexible as rubber braided hoses. (Minimum bend radius is much larger than with a rubber hose)
You can buy the industrial hose at most hydraulics places but you will not be able to get pretty anodized fittings or the hose you mentioned with the black cover unless you buy from an automotive line.
FYI I’ve had the same PTFE lines in my car for 6+ years with no issues.
