For my 65 Impala daily driver, I'm going to swap in a GM Ram Jet 350 TPI crate engine and a stainless TPI tank from Rick's Hot Rod Shop. The tank normally comes with -6AN (3/8") supply & return lines for use with braided steel hoses to handle the 45 psi. My local parts shop tells me that rubber hoses clamped onto a barbed metal fuel line exist today that are designed for such TPI pressure. First, is this true? Second, if so, which is more reliable for a daily driver? I assume the AN hose, but maybe the O-ring connector would leak before the rubber hose. What about a compression fit connector w/o an O-ring?
