Goes inside the pipe circled togive a good seal.
Gave it some beans leaving work on Thursday before the North London PF meet. BANG it went and I ground to a standstill.
Lost the part as it must have vanished into the undergrowth

. A quick check with Ford on Friday morning I found I couldn't replace the part
Things came good as I remembered the spare throttle body I had and low and behold it had one attached to it
Thank fook for that
