i was wondering what is the best way to drain/pump the fuel out of the fuel tank? i've got probably 1/2 to 3/4 tank of several months old fuel. as a note, the engine is out and the engine harness is not connected, if that makes a difference. thanks

easiest is just drop a hose down the filler neck and syphon it out....If you want to get all of it out just drop the cover below the tank and unhook the hose from the pump....

Move car outside, away from anything you'd prefer to not burn down. Disconnect the battery. Remove the fuel pump cover, get a 5-gallon jerrycan and a funnel. Clamp the J-shaped rubber hose between the internal and external fuel pump with a vice grips (set on stun, not kill), then loosen the clamp on the external pump end. Pull that end of the hose off the pump, direct it into the funnel, and drain off a couple gallons at a time. Clamp and repeat. My minivan seemed to enjoy the year old 91 octane, must have been a good vintage.

Stan will be along shortly to tell you to tie rags around your wrists. Not sure what kind of fashion statement that makes, but if it works for him, great.

It's very easy to drop the fuel pump cover and squash the rubber fuel line between the tank and the pump with something. Then disconnect the fuel pump and unclamp to fill up your favorite gas container. Clamp again when full, empty container somewhere else and repeat until empty.

thank you everyone! should i leave it empty or should i keep a some gas in it with maybe some fuel treatment. maybe i'm thinking to much

martin i would drop all the petrol (gas) if you intend to not run for a while because it will just evaporate away and leave the petrol additive like a varnish on the bottom of the fuel tank and in the fuel lines good luck

yeah i guess my thinking was the pumps would maybe "sieze" up or ? if they were left dry. engine should be going back in soon. hoping to be up and running finally by may

Rob Edwards

Martin-

The pumps should be fine dry- they come from the manufacturer dry. The seal on them might be another story, dunno.

If you're not 100% sure your internal fuel pump is good, I would definitely pull it (and check the inner hose while it's out) and then briefly test it with a 12V power supply (or battery). 2 years ago I replaced the original from my GT with a new unit. When I tested the original that came out of the GTS, it was making crackly death rattle noises (after fixing the split hose.... so I tested the spare old one I took from the GT. It was fine, so I R&R'ed the internal hose on it and put it back into my GTS.

If you are going to have the engine back in the car in May you could add fuel, with a stabilizer to minimize the condensation in the tank. If you leave the tank empty make sure that you drain any condensation out of the tank before you put fuel in it.

thanks rob! got the fuel out tonight. still smelled good. gonna pull that in-tank pump and give it a look

Be very, very careful - it is all too easy to strip the fitting out of the plastic tank...

will do Wally, thanks
