L78 Carb fuel lines?

[GM-26]

Thank you for the tip.

I called "The Right Stuff" this morning. Without hesitation they will be sending me an O.E.M. carb.to pump set-up. This is how transactions go, when you are dealing with professionals.

[YENKO DEUCE REGISTRY]

I too have had good experiences with them.

[GM-26]

Did you use teflon tape with the O.E.M. style lines?

[YENKO DEUCE REGISTRY]

No. These fittings are NPT, so they are tapered and designed to seal without tape &/or dope.

Probably not highly recommended by the purists but I've also used neoprene O rings inside the carb fittings. Just don't over tighten the fuel line when you put everything back together. I did this when I was playing with jetting and had the bowls on and off a lot. Left it that way for two or three years with no issues,...... and no leaks.

I have been told by others that blazed this trail before that
the only way to get stainless steel lines to stop leaking is
to use a flaring tool and re-dress the flares to make sure
they are perfect. I haven't tried this myself, but I will
be doing so soon ( with my SS L/78 lines )

Thank you Marlin...

When we bought our L78 car it had a cobbled up fuel pump to Carb setup. I bought the stock reproduction replacement lines. I had to tweak the two 90 degree pieces to get the centre to centre distances right. Other than that, they went together fine. The flare nuts have a straight thread and sealing is done by the inside taper on the double flared ends. The threads aren't meant to seal the fuel in, just to tighten the flare against the taper in the "Y" block or carb inlets. The stainless is single flared. Doubt you could double flare it anyway. When getting flared, the end of the tube has to be square or the flare will certainly be skewed off to one side enough that it isn't going to seal. Some cheap flare tools are just plain useless on steel and wouldn't even begin to do stainless. I've screwed up enough brake line flares to have some idea of what I'm talking about. It does take a little care and practice.
