Aren't you supposed to use flare fittings on a fuel pump? You didn't say what motor you're runnning, or mechanical or electric pump, so I'm assuming we're talking mechanical. My chevy's have always been setup with a factory hose fitting on the fuel pump for supply from the tank and a flare fitting on 3/8" mild steel hard line to the top of the engine. I never run a soft gas line up the front of my cars. If I'm off base here just ignore.
