Im putting the HHR in storage and need to drain almost a full tank of gas before it turns bad..
I know I have to jump the connectore in the fuel pump relay socket but Im not sure where to jump them and I dont want to short anything out..

can someone give me the pin numbers, thanks

 

Depending on how long you plan to store the HHR, have you considered a product such as Stabil, or other fuel stabilizer designed for storage?

 

Given the replacement expense and fragility of the in-tank fuel pumps used on HHR's, I would be hesitant at best doing what you propose.

Even overlooking the fire hazard present in transferring fuel, it's something that can be avoided entirely by using a good quality fuel stabilizer to prevent the gasoline from going stale, de-emulsifying, and forming varnish.

I've had great luck using STA-BIL products over the years, and it will keep fuel fresh for up to 12 months in a stored vehicle.

(Hey Oldblue, looks like we're doing the "Great minds think alike" deal)

 

Good point on the stabil - it does work well.

Beyond that, I'd be hesitant on offering details on the original request due to the danger of mishandling the draining of the gas. One does not want to mess around with gas fumes.

 

X2 to that whopper, gas fumes + spark = burn unit.

That's the last thing we want to happen to anyone here.

 

the gas is almost a year old now. car has been sitting for about 9 months I have been trying to sell it, no one has cash here so I want to get most of it out..might be too late for stablizer

 

the gas is almost 9 months old now...the car has been sitting unused, bought it for the ex, cant find anyone with cash to buy it

 

then I would only suggest neoprene hose and syphon the gas into 5 gallon fuel containers like used for lawn mowers, but don't use the fuel pump to move the fuel , it may overheat and fail as the fuel in the tank does keep it cool.

 

I'd fire it up, throw temporary plates on it and drive it to burn off the gas, then add fuel stabilizer and refuel till full. Leaving a tank empty unless totally empty (the fuel pump will not totally empty the tank) is just looking for problems with condensation/corrosion.

I've left a FI vehicle for a year without fuel stab., and yeah it had a nasty smell as it burned off the old gas, but it ran ok (maybe a hint rough for a little bit), and did not seem to cause any harm long term. But I burned it off in a couple of days, then refilled with fuel stab. and fresh gas. Worked great when I took it out of storage a year later.

 

I think there is an anti-syphon mechanism built into the filler neck that will not let one slip a hose in there. ???? Not positive tho'.

And a lot of places make it illegal to syphon gas I believe.
