Did the 4 pumps come from a catch tank fed by two pumps?

Some times multiple pumps are run to get fuel from each side of the fuel cell so there is less chance of starvation. One to each corner of the cell would be interesting.

Was the 962 CIS, MFI, or EFI?

I would think, pumps in parallel for quantity at moderate pressure (EFI).

Pumps in series for pressure which is what Porsche did with the 930's CIS.

Would the order of the pumps make any difference.

I was wondering if someone added a higher spec pump it might best be the last pump in series. Especially if they have built in pressure regulators. The one with the highest regulation spec might be best to have last.

Just spit balling again.
