:O I think that I need a shot of adrenalin to the heart or something. Given the price of that kit, I would expect the filter to be made of solid gold.
I'm going to be looking for a new seat then. There is a place which sells from the Trident catalog not too far from where I live. It's got to be less painful that the amount which the shop wants for the service kit (a punch in the face would be less painful too).
You just need to know where to look $9 isn't bad Shop Online
