Hey Folks,

I am going to be replacing some fuel line on the Duster and am curious if any FABO members have used the non-flare compression fittings similar to this one in their fuel system?
Earl's Performance Tube Adapter Fittings 165010ERL

I have, and use, a flaring tool but was curious it there are any down sides (other than cost) to using the slip on ferrule compression fitting? Seems like it would be a bit simpler and quicker to do.

Thanks as always and stay safe,
Pat
 
I’m not a fan of squeezing the the line to seal it like that.

Years ago (many years) Russell had a fitting that you slipped a collar over the line and then did the flare. I like that method much more than compression fittings.

Of course, if you don’t like doing the flare that’s ok too. As long as it seals you are golden.
 
the general idea of that fitting (a compression fitting) is fine
when I use them, I use a swagelock version
this has two ferrules instead of one and is rated much higher then your fuel system will produce

I actually used them on my brake system to splice in the line lock

having said all that, the ones is use are stainless
the one you posted is aluminum?

according to earls (not a company with a bad reputation) these will hold up to 250 PSI
you're running what, 7?
 
Thanks for the replies fellas. Much appreciated. Ya, not worried too much about the pressure, more curious about sealing with the ferrule vs flared fittings. Is stainless preferred over aluminum for fuel systems? I have no preference, will go with whatever works best.

Thanks again guys,
Pat

it isnt the sealing part i was talking about
i think the ferules in the one you posted are brass, im not sure what swagelock uses

my main concern is the body if it
i feel much better cranking down on stainless steel then on aluminum

however, all the ones i have used it to splice two pieces of tube together
going from tube to hose, maybe aluminum makes sense

i think most AN fittings are aluminum
 
I have used that exact fitting many times and they work great just don't over tighten it, and I have always used it on the suction side not the pressure side.
 
I wouldn't pay that kind of money for pretty colors. That's all you're getting. IF you insist on using the compression style, simply get them from a hardware store. Much cheaper. But I would not use that type anyway. I much prefer the female inverted flare fittings.
 
I just use them to connect the braided line to the steel line on frame rail at the bottom of the fire wall. If you are making it pretty why skimp on one fitting.
 
It's starting to look good

I’ve used them before with zero leaks. Also, ill never use push-loc fittings ever again. I cannot get them to seal no matter what I do.

3 lines?
feed, vent and return?

did you add one yourself?
The 5/16” and 1/4” were original, and I welded in the 3/8” feed line and used the 5/16” as a return and plugged the 1/4”. This was on my sand drag jeep CJ7 with a built AMC 360
 
I added a 3/8" line to my 70 cuda also, it worked great. I also found a 3/8 line filter like O.E. and pushed it on the end of the line so it had a filter in the tank.

They will work for a while , eventually will leak from vibration , intended for water system that dont move much , and will shrink the inside diameter of ur line some ....
