G&R 1/2" Duramax Suction Line Plug

When installing a sump with your Duramax, you end up with an open fuel supply line. Our 1/2″ aluminum plug will cap off these lines with ease, to keep fuel from seeping out of them and dirt from getting into your fuel tank. You no longer have to mess around trying to figure out how you’re going to plug off these lines. Simply clip our Quick-Connect plug into that open factory fuel line and you’re ready to hit the pavement!
