This 1968-1982 Corvette Molded Fuel Hose for the main fuel feed line is S shaped like original one so it won't kink and stop fuel flow.
A straight hose bent to fit will crimp under hear and fuel pressure, shutting off fuel flow to your Corvette engine.
Main Fuel line Hose, that connects tank line to fuel pump is usually soft and about ready to start leaking. It should be replaced along with the return hose that is next to it. Inside diameter of hose measures 3/8".
