Rodent damage to fuel tank fitting for generator supply
I have a 2011 Jayco Greyhawk that started having a problem starting the Onan 4000 generator. Suspecting that I had a fuel pump issue, as no fuel was getting to the pump, I changed the pump and filter. No joy, that did not help. I now started to check the hose for any signs of damage, found nothing til I got to the fitting on top of the tank. The fitting looked like it had been chewed on since the corner of the 90degree fitting was missing. It is obvious that it needs to be replaced which will require dropping the tank. I have no problem with doing that but the one area that looks to be very tough issue is disconnecting the fill and vent lines. There is no obvious access to get to that area of the tank. The tank is a 55 gallon standard Ford tank.630Views0likes0CommentsRe: 12 volt issue on 2011 Challenger 32 vs
Posted: 08/22/15 10:50am Link | Quote | Print | Notify Moderator I've been looking online at some suggestions, one is to check the inline fuse or fuses coming from the batteries. Would anyone know where these might be located? On my unit the solenoid mounted behind the battery has two fuses, one 5 amp and one 7.5 amp. I just had a similar problem and found the 7.5 fuze blown.377Views0likes0CommentsRe: Onan fuel pump or carb
I did get an initial code of three blinks but I inadvertently canceled it rather than expanded it. My unit is a 2011 and I am the second owner. I have excercised the unit on a regular basis and do use stabil. I did check the line all the way back to the tank and found no problems.368Views0likes0CommentsOnan fuel pump or carb
My Onan 4000 model KY L with 170 hours will start and run for a couple of minutes then it dies. Acts likes it is running out of gas. Knowing that the fuel tank was full I suspected the fuel pump. I disconnected the fuel input line from the filter and connected a short hose that I inserted into a gas container. Then pressed the Stop button to prime, worked fine. Next pressed the start switch and the unit started and ran fine for three or four minutes till I shut it down. Thinking that this confirmed that the pump was OK I put everything back together and restarted the unit. After about two minutes the unit started to sputter or surge. Did that for about 30 seconds and then died. I immediately disconnected the carb input goes and there was no fuel evident. Is it possible that the pump has degraded and can no longer sufficiently pump fuel from the tank. It seemed to work fine when I tested direct from a container from about two feet.2KViews0likes11Comments
