onan 4.0 fuel problems

[bill emery]

 i have a onan 4.0 model # BFA-1R/16004C . i had a problem in the main gas tank of the RV. the fuel pick up rotted away inside the tank. It left alot of small black mesh stuff in the bottom of the tank. I had the carb replaced on the onan and installed a inline fuel filter and changed it every time we went out for the weekend.

 It ran great for a year now i don't have gas in the carb.i replaced the fuel pump, installed a new fuel filter. It just won't fill the carb bowl. it will run if i spray carb cleaner into the carb but i think it is only running on the carb cleaner not gas. what could keep the gas from going into the carb? is there a fuel shut off on the carb? thanks for any help you can give..bill

Great! Nice of you to follow up so others can learn from your experience. I had the same problem with the lines in my '84, but the fuel filter caught the bits of rubber. I had to hack a hole in the floor to replace all of the lines (generator, engine fuel pump and return).
