What electric pump options are there? I’d assume you’d need a beefy alternator to power such a pump?
What engine do you have? When I fitted p38 PAS to my 88 I also converted to a 200Tdi, so it was easy and simple to just retain the factory Tdi pump setup.
I used a Peugeot unit in my RX7. Have no idea of output/requirement the P38 system requires though. @Dopey has just done it, not sure what pump he used.
