Okay, my car has sat just over a year. I treated the gas, but its coming up to the point where I just have to drain all the gas out of the car. I have tried to syphon it, but thats not happening. I just cant get it to go. SO..... I need help in a big way. Anyone else have ideas. I need to get all the old gas out and put fresh gas in so I dont ruin the car when I turn it over to the tuner in a few months. Any help would be GREAT!!!!!!

 

Bump.

 

Another way is through your back seats

 

Where the fuel pump is? I just discovered that. Either way I need a drill pump. So tomorrow I will buy a pump and get it all out. This will be a future reference for everyone on here haha.

 

Under the back seat there is 2 caps. When you open it you will see the gas

 

Shizzzzz. Please don't rail me on this one but do we have 2 separate tanks?

 

I run on biodiesel so my trunk is full of fuel... Not like that trunk holds anything else useful!

 

What?????

 

Moar details please urban.......

 

There are 2 metal lids with 4 plastic screws that hold them in place under the driver and passenger side rear seats. They aren't separate tanks technically speaking. it's 1 tank.

 

There is 1 tank, the design requires two separate level sensors and siphon tube to allow tank to drain.

If you can access the fuel pump relay than jumper hot wire to trigger it. Assume since FI you have a fuel return, just disconnect line a convenient location and run to gas can for draining.

 

I do have a fuel return line, but its on the back of the plenum. Just so anyone knows, as stated before its one tank, but you have to access it from both sides. The passenger side is the one with the actual fuel pump in it. The drivers side is just a livel sensor. I'm almost done draining but I use a drill pump, and it broke. 4 dollar part.

Pieces you need
1-3 drill pumps They burn out.
A hose
Drill
Philips screw driver

Patience

 

step 1: drill hole in bottom of gas tank
step 2: drain all of the gas out of the tank
step 3: post thread on G35driver asking how to fix hole in gas tank

 

I swear the is all ready a hold in my gas thank haha.....

 

you can disconnect the fuel line and give 12v+ to the fuel pump, the old fuel will come out.
