A new, OE quality rebuild kit for pumps with the smaller, 3/4" dia. valves. The 1" dia. valves fitted to earliest pumps are available individually, please enquire. In my experience it is not always necessary to replace the valves, the most common reasons for failure being a perished and cracked diaphragm or a worn out oil seal. Please note that this is the correct kit for pumps as fitted to Rover V8 vehicles, unlike some that are available and incorrectly described, UK postage free, overseas buyers please enquire.
