Hour meters are useful for folks buying the boat but a minus for a seller

Water pressure gauges is a great thing to have. Use a mechanical gauge and some 1/8 air brake line and Tee connect to the block drain or the Temp gauge at thermostat. Mine is at the block drain

Default Re : similar issues at a loss

So I wasn’t able to get over 3500 RPM so when I came back in I tested the fuel pressure after I diagnosed everything else and I’m coming up with 29/30 pounds at idle and 35 at key on.

I removed the fuel, cool system, checked everything replaced the fuel pressure regulator, because the one I had was rusted out at the vacuum connection. replace the fuel pump check the wiring and then I put everything back and I’m getting the same. I also replace the filter on the fuel water separator. Hold pressure pretty well, so I’m not worried about the injectors leaking and I just had them all flow tested.

There was an intermittent issue at the relay, but I fix that.

Any help would be appreciated I’m buying beers.

Also, if anyone has a scan tool for this military, they’re willing to lend me or live in San Diego. Let me know.
