This auction is for a 5/16" billet machined plug for fuel injection hoses that use a quick connect system. This is made of 6061 aluminum and it uses a raw machined finish. 

 This block off is for plugging the fuel line to keep the gas and fumes in and the dirt out while you have it disconnected. It locks in just as the filter or line would. We gave it plenty of room for a disconnect tool and your fingers to fit at the same time and a nice big end to pull on for easy use. 

  Only the 5/16" plug tool is included in the auction. I have a 3/8" and 5/16 set as well as a individual 3/8 plug on my ebay store.
