Resurrecting an old thread.
I just ordered two seal kits for my 701 helm pumps from Olympic Drives & Equipment Ltd located in Richmond, BC.
They use a shipper that takes the item to the US and ships via USPS. I received the kits in four days. Cost including shipping was $62 CND. With transaction fees it cost me $45.34 USD. The kits they sell include the cork gasket.
The stock number is 119-0002.
I am very pleased with the price and their service.
