Brake Fluid Resevoir Cap size please

[Porsche Pete]

Going to order a Power bleeder today... Cant find the Motive ones over this side of the pond, but Sealey do a very similar one..

Question is, what size is the Res cap.. The Sealey unit is 42mm for `Euro cars`
but i am sure i read somewhere the boxster is 45mm ??

Thanks in advance..
