4AGE oil pump circlip size?

[TERRA Operative]

Ok, so I've gone and lost the circlip for the bypass relief valve in the oil pump for my 4AGE.

Can someone please measure the size of theirs for me if they have it apart? I tried a few metric sizes at work but none fit.

Ok, turns out it was a size inbetween the sizes in out circlip set at work.

For the record, it's a 15mm circlip, and you need 14mm washers to shim the relief valve if you so desire.

Some good info here on how much to shim the pump.
