Ok not sure if this will help anyone. Yesterday I done the diode mod, which went well I'm glad to say.
I then decided to drill some holes in the air box. I noticed some tape covering a hole that obviously use to go to a pipe but the previous owner had done a lot if bypassing and forge hoses. I went to get some tools came back outside to find my mate (who hates mods on cars) had use a milk bottle cap which fits solid in the hole perfect fit!!
Oh it was s purple top if your interested should of used full fat me thinks
