fuel line connector

Hi, Replaced engine with one out of a rover 75. Everything has gone smoothly so far but the guy i bought it from just hacksawed the fuel pipe at the connector with the fuel rail. when i tried taking it out the entire connector has disintigrated. the original one on mine isn't much better.
do i need a new fuel rail or fuel line or can i get the connector.

any ideas?????

What colour is it?

Engine?

the connector on the pipe is red and its the 1.8 k series
