Retired and recently started annual maintenance on my very low hour 1999 Honda 130HP. Full maintenance with filters, oil, plugs, impeller, gear oil, etc.
Motor cranks (with NO hint of starting) and gas is venting down outside of motor. Motor worked fine last year. Vent filter above vapor separator is filled with gas and this vent line is where gas is coming from. Drained vapor separator x 3 per shop manual and everything looks good. When I pump primer bulb gas refills vapor separator and goes back up into vent filter. I haven't yet changed high pressure filter but one on engine has less than 75 hours.
Ideas:
1. Vapor separator float stuck pushing gas to vent out
2. high pressure fuel pump is not working
3. Electrical problem starting fuel pump
4. High Pressure filter clogged ??
Dealer recommends upgrade to new Vapor separator Assembly which is over $1,000. Will this still fit a 1999? One giant problem is that I still have the original Vapor Separator/Fuel pump setup. O rings for vapor separator are unavailable which has me not wanting to open it up if I don't need to. Can you use another sealant in place of O rings as a solution? If fuel pump is toast - since I can't get a replacement then upgrade may be only way to solve.
