    Unhappy Stale Fuel

    My Baja 192 with 5.7 lx has only done 60 hours but has been layed up for 6 years, I followed the correct lay up procedure except for draining the remaining 5 gals of fuel. When I come to restart the motor the only way it will fire is if I pour fuel down the carb or supply a fresh fuel feed direct from a can to the fuel filter. Will I need to drain the old fuel, will it be gummed up or will I be able to pour some kind of additive in and all will be well he says hopefully?

    Here in England we are expecting a mini heat wave, temperatures are expected to soar to 20 - 22 degrees ha ha, and now I have some time, I want to take advantage of this "tropical" ,weather.

    The 5 gallons that are in the boat are no longer a viable fuel after 6 years, in my opinion. I would try to pump it out. My boat has only been sitting a bit over a year and I plan to get all of the fuel out of it and start with fresh.

    Thanks, I'll do that. I've heard someone say the fuel could have turned into a jelly like substance, if this is the case will I be able to add more fuel to turn the existing fuel back into a liquid form before pumping out or will I need to mix with something else?

    I have never had to deal with that situation, so I can't say, might be worth a try.

    The entire fuel system may need cleaning, certainly the fuel filter needs to be replaced. I would guess the carb probably needs to be gone through, but possibly not if it evaporated out of it quickly enough. Certainly something you want to be aware of when you start it up to make sure it's not dumping lots of raw fuel into the motor.
