 Topic: GT-40 fuel pressurePosted: July-27-2016 at 12:42pm |

I posted a few days ago with a engine stumble issue. My fuel pressure is 38-40 with key and @ 34 running at idle. Is this good or what should it be? I have not driven the boat to see if it varys yet. I did replace the pump and eec relays the pressure before changing the relay was @ 30

40 is what I would expect. there is a fuel injection manual in the reference section for Gt-40 motors, if you'd like a true confirmation and troubleshooting guide. The Poormans GT-40 thread is a good resource as well.
