    No need to cut anything but the ends of the hoses that used to go to the throttle body on the old engine. You don't have a need for the Corvette fuel filter, the stock filter will work fine. Take your tubing cutter and cut the ends off the old connections, remove the threaded fitting and apply a piece of hose to connect it to the snap-loc fitting(3/8" to 3/8" and 5/16" to 5/16"). The stock return line will return excess fuel pressure to the fuel tank. Depending on how long your hoses are you could cut the rubber hose and use it or you could cut the metal tube and join it to the snap-loc fittings.
