That isn't what I have on my car mate, mine's a 1998 Gti which has an efi zetec engine

But I'm pretty sure from the pic you posted I'm thinking of the right bit, I'll see if I can find it in the garage tomorrow and give it a try

(Finding it's easier said than done as my mate has two fiestas, two quad's and a moped in there at the moment ... it's a bit crowded to say the least )
