I may have an answer to this issue. It appears the later version of the B28 engine used from 1982 onwards in the Volvo 760. This had the altered water pump. We knwo this because the guy at the parts place I was using went and found the " h " shaped pipe that it hooks up to, and it was the same as the DeLorean! (is port on the left). This pipe was off a Volvo 260 circa 1979. Anyway, it appears the pump from the DeLorean cross-references incorrectly over here to the later pump with the ouput port on the wrong side Airtex is an american manufacturer of european parts - we can't get that brand over here. Ironic really.
