Gas smell and probably a beaten to death topic.

I made the mistake of using the old school extruded rubber lines first time I did an AN fuel system. It was fine for a while (Earls brand too and not some off-brand Amazon junk). Took about 6 to 9 months and I started smelling it if it was parked in the garage for a few days. I imagine over time it would get worse. PTFE is the only 100% guarantee you'll never get fuel permeation through the lines.

I used Earls XRP for 15yrs on my Cobra without incidents. I changed to PTFE during my frame off. I use Fragola on my Coyote. I never had a gas leak or smell with the XRP. No exotic fuel as well. I do agree that PTFE lined is the way to go.

And I think someone already mentioned it, but you gotta be real careful about accidentally mixing/matching one brand's fittings with another's hoses. That's another reason I stick to one brand whenever possible. I've come to know Earls and XRP quite well over the years. It's not sobbery when I say I only buy their products (mainly Earls).

[RAU03MACH]

i would need to look at mine to make sure on size

 

[RAU03MACH]

i want to say yes

 

[RAU03MACH]

i have 2 of them 1 of them is the small fuel feed
the other is a little larger for fuel return but i need to check that size

 

[cobrajeff96]

Most likely a 3/8" feed line. That's what the original size was on the 96 Cobra anyway.

 

[weendoggy]

I thought all the 5.0 SBF's used this style of fitting to the fuel rail: https://lmr.com/item/KP-5070/1986-98-Mustang-6An-And-8An-Fuel-Rail-Adaptor-Kit At least mine did when I swithced to AN fittings when I had this setup. Didn't mess with my cross over because it wasn't bad. Otherwise I would've put a new setup in lieu of the stock one.

 

[RAU03MACH]

ya you can hook into those
but im changing fuel rails also on mine only to get away from the cross over hose at the front or rear of original fuel rail

 

[RAU03MACH]

the one he is showing is the fender well fuel sup/ ret

I think the 94/95 have a different size hard fuel line than the 96-98

 

[RAU03MACH]

Ya that is what I'm thinking
Just don't know the sizes for sure

 

[cobrajeff96]

The feed is usually larger than the return if that helps.

 

[RAU03MACH]

I can't remember for sure
On my 95
I unhooked the lines and had fuel psi comming out of the smaller line that has been a while back
I'll have to check it again when I redo everything in the engine bay

If you are referring to the rubber sliding. That is just the protective hose. The actual line is a harder plastic underneath on the barb.
Also the Tuning Innovations lines are top notch, I have them under the hood and at the tank
