I think I ran my Onan quiet diesel out of fuel. Didn't know

Customer Question

I think I ran my Onan quiet diesel out of fuel. Didn't know the fuel pickup was higher in the tank. Anyway it spins over fine. I've changed the filter. ( fuel was present in the filter). I've tried to prime as recommended. Tried about 20 to 30 times no luck. Any suggestions?

My name is ***** ***** I am going to assist you with this.
What is the full model number of the genset, exactly as it is written on the data label?

Its going to be kind of hard to tell you what to do if I don't know which model it is.
But the first thing you need to do, which covers all models of diesel, is to do a fuel flow test.
From underneath the genset, disconnect the fuel return line from the barb on the genset.
Attach a piece of fuel hose to the barb, and place the end of the hose into an empty container of at least 1 quart capacity.
Press and hold the STOP/PRIME button for exactly 1 minute. In 1 minute, it should pump a minimum of 1/2 pint of fuel.
Does it?
