does anyone have an extra or kno of where I can get one for my 86 xj6? the after market ones ive checked out don't seem to fit my bottle.

 

Hmmm.
I am reasonably sure that the bottle in my 83 S3 is OEM. But, the pump seems an aftermarket unit. Just a square block with an ih hose and an out hose and ground and hot wire connectiors. I bench tested it and it works. But, not in the car. Switch, connectors wire issues somewhere!!

So, an external pump might be what you need.
