Thanks Sean, glad you got what you need.
I've just filled in a parts request with them, fingers crossed they have one and don't want the earth for it. :)
Thanks Stevo,
Yeah, I know it's different - it's the cylindrical one with two inlets.
I've been looking for a month and can't find one anywhere, just thought I'd ask here, on the off-chance that someone has one. :)
They seem to be like hens teeth! I still can't understand why the previous...
I just bought a nice low mileage early ph1 172 and am returning it back to standard, so I am after one of these too if anyone has one for sale?
I'm in south Northants.
cheers!
Jim :)
