Pump Set.diaphra

The diaphragm when old and worn is usually degraded, split and with a weak spring and plunger action - it is a lot easier (and if time is money, cheaper as well!) to compliment your restored carburettor/s with this brand new, high quality OE item.

Order all the gaskets, seals and other new fasteners at the same time and reduce the shipping costs with one larger order!
