where are you located?
If you're in Europe, then you could try Ford part number
86AB-9350-CA. This pump will have a yellow paint dot on the outlet casting.
The performance for this was 150 litre/hr at 5.8 bar - this is a modest performance spec compared to samples I had which would often approach 180/190 lph at 5.8 bar.
Running these at lower pressures results in about 250+ lph at 3 bar - from memory, I no longer have the data.
This pump was used on turbocharged K-Jetronic fuel systems, so I imagine that other European manufacturers like VW, Opel and Mercedes had similar requirements of Bosch. Perhaps the supercharged VW Corrado used it?
