Any ideas folks i wanna attack it this weekend. I'm hoping that taking it out, cleaning it and putting it back will cure the leak. But if it needs replacing i don't actually know what i need....hahaha

Most probably just needs a new o-ring - other than that I know nothing!

Bit late now but it's the commencement of injection sender that bit is...tells the small ecu where the pump timing is for cold running smoothness improvements...very basic system and a bit unessarsary really.
