Attention Onan 5500 Marquis Gold owners

Just got back from repair shop.My Onan was leaking gas. It would run fine but the gas was leaking badly from a fitting on the inlet side of the carb.The repair guy said it is a known trouble spot but Onan has chose not to do anything about it.This to me poses a serious fire hazard,you have no indication anything is wrong, it could run for hours before the gas got to a hot spot that could ignite. My Gen is in a 2004 RV.Don,t really know when Gen was Manuf but should be in that time frame
  • Does your generator still have the fuel filter attached to the bottom of the carb? That is a known trouble spot and Onan did do something about it. The fix was to replace the filter with a straight through adapter such as this one. Your "repair guy" should know about that. There is another filter located at the fuel pump so you won't be without filtration.
