i have a racetech oil pressure sender and need an adapter to make it fit my zetec

any i dears, or what thread sizes they are?

Call thinkautomotive or Rally design. I am pretty sure that they will know and be able to supply you with one for peanuts!

just be aware that there are usually two lengths and if your pressure sender is 40 mm wide then you need the longer 50 =mm adaptor.
