Stainless braided fuel lines

[1976Blazer76]

Is it ok to run stainless braided fuel lines from the gas tank to your fuel pump, then from fuel pump to carburator? The lines have a 9/16" Outside diameter. I'm running a holley high flow fuel pump. This should work just fine shouldn't it with the right fittings?

There are two main types of steel braided lines - nitrile and teflon. Most likely your 9/16" OD line is 3/8" ID nitrile. My experience has been that the thin nitrile doesn't hold up very well to modern gasoline with it's large amounts of aromatics. The teflon line is normally used for brake applications (3/16" and 1/4" ID versions), but 3/8" is available and it is impervious to gasoline. If you want to use steel braided line, that is what you should use. Make sure the ends you use are designed for teflon steel braided line - these fittings are typically steel, not aluminum.

EDIT: I checked Aeroquip's site. Their standard steel-braided rubber hose isn't nitrile, but some other material that they claim is compatible with gasoline. I don't know - even nitrile is supposedly "compatible" with gasoline, but I have seen 'em get rotted out and leak. Personally, I would stick with teflon...
