New o ring for the nissan gtr r35, recommended to be replaced when accessing the fuel pump as the old one will have swelled and expanded from absorbing fuel vapour over time making it impossible to reuse. Comes with 6 new bolts as it is very easy to lose bolts when removing the old ones that can disappear down the back of the fuel tank. O ring is a much improved petrol resistant material which will be a lot more resistant to absorbing fuel like the original and expanding preventing the seal to be reused. O ring is supplied in either black or green depending on availability.
