Fuel line in engine compartment

Instructor
While I completely agree that a metal line is much more durable than rubber, the SAE 30R7 low pressure fuel grade spec has a burst rating at 250psi.
With that being said, I am plan on replacing my rubber lines with metal ones this winter.

So I changed my fuel pump, and auto zone sold me this little nipple to go in the end that sends the fuel to the carb. Well, once I hooked everything up, fuel kept dripping out of it (through the threading). What should I put on it (and then screw it back in) to prevent the leak? This has become the project from hell... Garage still smells like gas..

Teflon tape around THE THREADS ONLY would probably solve the leak - the tape doesn't seal but it does let you tighten the fitting tighter so it doesn't leak. BUT that doesn't solve the problem of eliminating the hose. You need a hard line as has been explained many times in this thread.

I think this thread needs a bit of a reality check....are steel lines less likely to get damaged and leak fuel yes but how likely is a fuel injected pressure rated fuel hose like the auto stores sell to leak? I intended on using the stainless braided "bling kit" that I have to further protect it and I have hard steel line from the pump up to the 90 degree bend at the top of the engine so the hose will be about 16" with a fuel filter in the middle because MOST fuel filters are for rubber lines...
I would thing the more realistic thing to worry about are those poorly designed holleys that can leak fuel fuel...If anything its a most realistic scenerio than a properly routed and secured rubber fuel line....
I'm Just saying its not as dangerous or unsafe as this thread is making it out to be.....my motorcycles all came new with rubber fuel line just inches from the engine and straight to the carbs..as did my tractor and numerous other motor driven vehicles and tools I own....
If you neglect it for years the rubber can break down..... so know that and maintain your vehicle which you should be doing anyway.

I in the middle of creating this same setup, except I'm using stainless braided line. Couple of questions for you - how did you keep the line away from the lower radiator hose and engine? Did you have some sort of a clamp or similar on the line?
My other question is - what fuel pump where you running? I noticed you did not have a regulator, and I have concerns with this Edelbrock carb and fuel pressure being too high (they recommend 6.5 psi for it). FYI - I'm using a stock replacement pump.
Thanks!

Wouldnt sweat rubber line too much long as the metal ends are flared and its not rubbing on anything. Sure hard line better but still-
Onthe glass filter the seals inside may leak, mine did sooner rather than later. Caught it breaking in a cam, lucky.
A thread in metal type filter is ideal
