The 15th May (MSD setup) is getting ever closer and i still have not fitted my 5th injector to my car

Reason is i have most of everything i need except the fuel line going to the metering head, i think this is all i need now. But where do i get it from and what am i asking for? theres all types of ends etc im really stuck

Can anyone point me to the pay button online lol to what i need to buy?
Thanks

Danny
