Fitting a mechanical oil presure gauge

[Toby S]

I've finally decided to fit a mechanical oil pressure gauge to my 1992 Supersport - got sick of the variable readings from the electronic gauge which seems to have a mind of its own (getting on a bit like me and has good days and bad days)

Now for the really stupid question - after plumbing everything thing, I assume I will have to bleed the system at the gauge end to get the air out and oil in the tube - correct ?
