what size tap to convert mk2 oil filter

[saxo_vtr_1994]

im gunna convert my mk2 oil filter into a mk1 one so i can fit my raceland manifold, i know i need to use a m10 tap but what size as when i look on ebay for one i can get:
m10x1.0
m10x1.25
m10x1.5
does it matter which one i get???

Yes it matters the 1.x is the thread pitch you need to have the correct one

What that is I'm not sure

Pitch would need to match the bolt your using to block it.

M10 x1.5 is a course thread and classed as "standard" .... If you got a m10 bolt from b+q then it would be a 1.5 pitch

The proper Citroen internal hex head bolts that come with my kit are M10x1.5.
