Whale pumps do not do a Mk IV kit anymore, so I assume it is upgrade time, lucky my financial calcualtions were on the back of a fag packet I threw away!
Thats sad news They do have a man who is retied from the Co his name is W.J. Gilmore 24, Springvale Rd Ballywalter Co Down BT22 2RS TEL: 028 42757305 try giving him a ring.
I got some spares for a brass pump from him he may be able to help you with your Mk IV.
I am lucky I have some spare bits for mine. After that it will be a MkV. But don't give up hope check out ebay.
