Fuel pump or hose to RV gas tank could need replacing.

Testing the fuel pump is fairly easy . . . disconnect your gen's fuel hose. Then connect another hose that's inside a gas can. Start your gen. If your it runs, then it's probably the pump.

NOT on an RV generator no... The fuel pump on most RV generators is external (in-line type) and if you disconnect it and stick a hose into the gas can no gas will flow up into the carb.

Easier to disconnect the pump outlet side and stick that hose in a clean 1 gallon glass bottle.. Now hold the STOP switch till the pump starts filling the jug. then touch Start and Stop to kill the pump.

IF it pumps. it's good.

Home was where I park it. but alas the.

Check out Test 28 - Check Fuel Supply in the Quietpact 75d Diagnostic Manual.

It's similar to the Onan diesel gen Fuel Pump Test which says . . .

Disconnect the fuel return hose from the line to the supply tank and point the end into a container of known volume . . .
