fuel line to tank connections: rubber or steel

[Hray]

I was looking at the few inches of line needed to make the connection. I seem to be having problems with rubber fuel lines lately because of the additives in this new fuel. I was thinking of using some steel and compression fittings on this so I would not have to worry about rubber lines going soft or leaking.

I Welcome any suggestions.

Ray,
As long as the line is "marked' FUEL, you should not have any problems. It's normal/ordinary vacuum type lines that will create a nightmare with plugging carb passages, filters, cracking, bulging, or just plain leaking.

I assume you are just using the hoses for the beginning and termination of the fuel lines and not running a 12' long rubber line?

Hray Ray Steel is ok IF there is NO movement of the tank in the frame or twisting of the frame under hard driving. Plastic would be better. It would remove the vibrations from the connections. Compression fitting ARE not the best idea for what you are doing. I have seen the break, leak, and even crack lines where the furrels are crushed on the lines. Have a fitting welded on the gas tank to what size you need. #8 or #10 would be the best and run a 3/8" or larger gas line to the front of the car and a 5/16" to return. Regulator with a 5-6 psi opening and closing to not have the floats in the carb bouncing and washing down your cylinder walls in the motor. Rick L.

dv: yes only doing the couple of inches of line at the tank. if hard lined i would more than likely do a double flare like on my brake lines and use two couplers.

and I do only use fuel line not vacuum for this purpose, maybe I will use fuel injector flex line, this may have more resistance to the chemicals in fuel.

It just seems to me that even with fuel line hose and when it sits for months without fuel running thru it that it wants to just sit there and soften the hose. maybe when the fuel begins to break down it attacks the insides of the hose.

Thanks for advice. Ray

Hray,
Rick does have a very valid point about vibrations and flat movement of 'hard Connected lines. By the way NHRA-SCCA etc. do not allow the compression fittings you are talking about. Thought you may want to know.
