Description: For sale is a rebuilt water pump I have in my stash. I have no car that takes this, so I’m offering it at a very reasonable deal. It is casting number P30961A used to 7L42594, but would likely fit other applications if you only need a single groove pulley. Moss sells this rebuilt pump for $468.99. I’m only wanting $75 plus shipping.

That pump is 1968-1971 only on emission cars such as US. I have 12 in stock. 1972-1973 is the same except for an additional pulley for the air pump.
There is no S3 pump as a single item. Early cars used the same pump as later S2. 1982 model year in US went to a four-bolt fan clutch and the improved bypass system. 1985-1987 US model year gained a larger impeller and improved water flow. 1982-1984 pumps supersede to the 85-87 part number which is why I sell only the later ones with the improved cooling.
Indeed. I’ve often wondered about that strange design, given that the internal bypass orifice itself is tiny. I concluded years ago that the large outlet is intended to substantially increase the volume of the tiny header tank above it. A typical Jaguar kludge, in other words.
Just remembering,…I fit this early one-pulley pump to my 73 after removing its smog pump. I didn’t want the Missouri inspectors to notice an unused pulley, a dead giveaway that it had been desmogged. Then much later, when I added an S3 water outlet and radiator (part of the project that included a Mark X intake) I believe I used BSP bits to reduce the bypass spigot diameter on my S1 pump to S3 specification–and I still have that S1 single pulley pump. Would have bought Tim’s spare if I were flush enough with cash; a great deal.
