In case anyone is interested. I finally received the service manual today and the fuel pressure on the high side should be 20-30 psi on the larger engines and 18-32 psi on the 15-30 HP.
Chris, the injection pressure would be that high, but there is no way to measure it. You can only measure the pressure at the injector inputs. 20...30psi is correct there.
Hay Werner, where were you a week ago when I needed that information?
Trouble is, the pressure is OK so now I have to get into the electronics. But at least I've got the book.
