[T3] FI fuel pump rebuilding

["Jim Adney" <jadney@vwtype3.org>]

I've managed to make the parts I would need to replace the parts that 
usually fail on the FI fuel pumps. Now that the parts are here, I 
should be able to turn these around in a week or so. If you have a 
fuel pump that still "runs" but doesn't pump, or if your pump has 
developed a leak out thru that little cap on one side, I can fix that 
now.

The repair consists of a new brass cap, much heavier duty than the 
original alum one, and a replacement Teflon tip for the little piston 
that's under the cap. I'll also replace the O-ring under the cap and 
the 2 O-rings that seal the pump wafers to each other. I will not 
disturb the O-rings that seal the motor housing or the 12 V input 
connector.

The price for this rebuild is $60, which includes return shipping. 
Once this repair is done, these parts will be better than new.

Unfortunately, this is not a DIY job; I can't just sell you the 
parts. I have to finish machine the Teflon button after it is pressed 
into the steel piston. This is the only way to get the shape and size 
of the final part correct, so I have to have your parts here to do 
the installation. 

At this point, I'm only sure that this repair will work on the late 
pumps, the ones that have all 3 ports pointing in the same direction. 
It's also likely that this repair will be equally useful for the D-
Jetronic pumps used on Volvos, Saabs, and Mercedes, but I haven't 
tried any of those yet.
