Window Washer
Another part that gave up the ghost was the windshield washer pump. I took it apart and cleaned the pump part (gear section), but all it did was draw a lot of power and not turn. As the motor was not made to be taken apart, I drilled a couple of holes to squirt some WD-40 in where the bearings were. That got it turning, but it would slow down after a few seconds. So I decided that a replacement pump was needed. I took the old pump and bracket down to the NAPA store and explained that I needed a pump that would be about the same size and fit. At first they wanted to look up the right part. After I mentioned that it was for an old Ferrari, they gave up on the idea and just brought out their entire stock of replacement pumps. After opening a bunch of boxes, a Balkamp #665-1593 washer pump looked to be the best fit. It did need a strap fabricated to hold the pump to the bracket. This picture is of the one that Lowell Brown fabricated when he had to replace his pump (I forgot to take pictures of mine). Plus his bracket is much nicer, being cut from the back of an old mailbox!
An update on the windshield washer pump.
Original
Ed Montini found a BMW 2002 pump that looks almost identical to the original. The part number is P7050-21282 and can be bought from www.autopartsimport.com. Here's a picture from their website.
The only difference I can see is that the bracket doesn't have the same hole locations as the original one from my 330 GT and the wire spade connections are in different orientation.
Note, it is now listed under 1970-1971 BMW Bavaria model.

Interestingly enough, when I followed the auto channel link, I ended up on eBay with a slightly different picture.
The good thing is that the bracket looks to have the correct hole pattern and the price is only $30.40 w/free shipping. So I ordered one.
The pump came and look identical to the original one in my car.
The pump is located underneath the battery tray, so the battery needs to be removed to change the pump. The left picture is looking down between the foot well and the battery tray. The right picture is taken from the side by the header heat shield. These are of my 'old' replacement pump.
The old pump out of Lowell's car (left side in pictures) was different than the old pump in mine (right side). Further, mine has a date stamp of 9/69, so wasn't in the car when it was made. Lowell's pump is also a VDO, but dated 4/66, appropriate for when his car was built. Originally I was going to use the motor from Lowell's and the bottom pump portion from mine as Lowell's leaked to make one good pump, but couldn't due to the different design. You can also see that the base design is different and the attachment slots are slightly different. So I think that Lowell's old pump was original and mine was a replacement from a couple of years after my car was made in 7/66.
Installation was pretty straight forward as the slots almost fit the original bracket. I ended up only using two of the four screw locations since I didn't want to modify the new pump base.
One trick to get the new pump primed is to take a mouth full of water and force it through the hose from the washer bag. Otherwise, the pump will probably not pull water out of the bag.
