Here is a link with all the info, hope it helps!

That is a VERY good link. Interesting, as they say to use the "L-Jetronic" pump (which is what the '75 Opel has) and just modify the Spica outlet restrictor port by making it smaller (from 3/32" to 1/16"), to ensure the supply pressure stays within design (15 to 18 psi). I would have thought that the L-Jetronic pump, designed to run at 42 +/- psi, would cause problems, but it is the recommended replacement pump for the Spica fuel injection system. Apparently the L-Jet pump has a bit lower volumetric output, so the port has to be decreased in size to maintain the recommended pressure. I wonder why they didn't just use a pressure regulator like the L-Jet system does?
