Seeing the price for OEM quite shocking have for about 20 euros managed to upgrade my original Lucas washer bottle with replacement pump, waiting on a none return valve with filter for bottle but pleased with results, already had the Dremel so not included in total !

 

it is missing a pickup extension that almost touches the bottom of the glass container ? A straw might do it.

 

the pump is a 2SJ with points.

 

With none return valve and filter fitted

Finished except rubber for frame.

 

Nice job.
I added push-on Welting to the edges of the bracket. It prevents the glass container from flopping around.
