Emptying the Grand Wagoneer

[WSC]

I checked the Fuel section and I see that a bundle of you have removed the tank to replace it, but that's not my problem. My Grand Wagoneer has sat for too long with the same gas in it and I would like to remove this old gas before I attempt to get the old girl running again. I bought a garden variety squeeze bulb siphon at Kragen and I find that there is no way I'm getting that thing to go through the gas tank tubing to actually be able to siphon the tank. How have you guys solved this problem in the past? I figure I've got to get about 5 gals out of her.

All suggestions greatfully accepted.

If you have an electric fuel pump or can get one cheap, try emptying the tank with that. Once it is empty, dilute whatever may be left with fresh gas.

You may be better off dropping the tank and cleaning it out. Depending on how long it has sat, old gas can turn into some nasty goo.

The circle of metal with four rivets in it covers the access to the gas tank. If you pull back your carpet, drill out the rivets, unscrew the plastic cap that contains the fuel sock (after removing the fuel lines) you will have access for your pump to work.

This is what I did on mine. There may be an easier way, but I couldn't figure it out. :)

I worked for an old school guy and he taught me the best way to start a siphon. You need an air compressor. Get set up like any other siphon job. Instead of appling vacuum with you lungs or something else blow compressed air ACROSS the hose. This will set a low air pressure zone and soon fuel will start to flow.

be careful to not damage the fuel sending unit, its pretty fragile, and usually need to be replaced, found this out the hard way

After accessing the access hatch under the rear seat, use one of those cheapo siphons you buy @ the parts store. Wear gloves because the siphons ALWAYS leak. Unless you like smelling like 85 octane. :D

You probably only need to empty out 1/2. Put in some new gas and it should mix just fine.

newer gas really doesn't go bad like the old stuff use to. how long has it sat around?

Why not get the over-the-counter seafoam or Heet, something like that; we did it to our truck, since it had been sitting for quite some time itself, and we needed to clear it's throat to see if the engine still ran. It worked.. maybe try that first? It had to sit a few days with that stuff in the tank first though.

i dont know if a gw is the same but i have an poly replacement tank and to get the gas out so i could drop the tank i just disconnected the large inlet put a long rubber hose in there and siphoned it into a gas container. not the best taste or smell but some corona was waiting next to me :D

I used aquarium air hose and lung power. It was slow but on the bright side the bad taste went away after awhile.

Sea foam has worked for me. Last year I also ran fuel from a car that had not been licenced since 2005 in my 82 J20. The only fuel problems I have had lately is that a 240Z that had the tank cleaned/coated seemed to have the coating desolve into the fuel and plug the carbs.

How full/empty is it? Put some octane booster in the tank and fill it the rest of the way up and run it. Change your filters when your done.

The "OSG" I worked with would feed the syphon hose in, stick the air hose to the fill neck, and wrap it with a rag and hold in on it . A couple of short blasts and it would start instantly.

I dropped the tank and they aint been right since...:banghead:

Is two years more than you want to go. Mine has about 10 gallons of the stuff in there. It smells pretty raunchy:cool:
