Thanks Richard,
That was my fear from looking at the flowchart..

I run batch fire for fuel injection, but maybe you know if DTA (s60-pro) fires per side (so not really a batch of 4 but a batch per 2 cylinders)?
That way I might be able to use your method with the two diodes and triggering the 2d twice?

If that doesn;t work, do you sell such a pusher pump? I fear the small 4mm lines might not fit any window washer pumps. Fitment of lines is usually a nuisance when you start fabricating on your own..
