Yeah that was after i'd taken it for a run and got it nice and hot!! Was sittin at just below 2bar (20-25p.s.i) minimum, and like u say went right up when canin it. Tis an electrical one so yeah i bought the sender unit/adapter and wired it all up correctly. Was hopin it was ok as it's a fresh engine with a new oil pump, just wasn't sure what it should be! Cheers mate
