I'm with Gilles. I don't think the F9 relay can be directly adapted to replace the OE FP relay. It would require some additional creative wiring. The Hella solid state doesn't look like it will work either.

The CIS does not need the pump to run to prime it. Lots of SC's start on the first turn of the key.

As for reliability, I'm pretty sure the CIS relay in my 1973 car is original, and it's 50 years old. Hard to beat that.
