Where is fuel leak on Onan Diesel Generator

The alternating seems to not be producing electricity. It reads 13 volts.

^Yup, pretty sure it's fuel injected. Thanks for getting the crowd back on track.

As for diagnosis help, OP, please describe your issue in as clear of detail as possible.
"found it. alternat is no producing" does not help anyone help you.

We have to be missing something here.

Title says DIESEL Onan Generator.

And comments by others as well as OP are discussing carburetors/gasoline issues.

Please tell us exactly what generator you have. And, is the problem a fuel leak and/or a no start.

If no start, how far into the "run" cycle do you get:
Fuel pump clicks?
generator turns over at low or normal speed?
generator starts and runs or dies?

yes

Are you saying the new fuel line is not producing fuel to the carb?

Thanks all. found it fuel line. now my alternate is not producing

How well does the Onan run, does it act flooded
Check the carb for a bad float
Check fuel hose to carb, might find a crack

We can't get it started yet. pre covid we ran it 24 hrs day for a when off hookup

Moved to Tech Issues forum from DIY.

If the RV came with the generator installed as original equipment it probably draws fuel from the RV fuel tank.
