How to remove your gas tank from your Corolla GT-S in 10 steps.
Open the trunk and unscrew the access port for the
fuel pump and level sending unit. Then unplug the two sets of wires and
tuck the ones on the tank side under the trunk floor through the port.
Remove gas cap and unscrew plastic 'shroud' just below the mouth of the
Put a large drain pan under the tank (large enough to hold the amount of
fuel present) and use a 3/8" drive ratchet to unscrew the fuel drain
plug at the bottom of the tank. Screw the plug back on when done and
remove drain pan.
Jack up rear of car and keep up with
jackstands placed under rear axle as far outboard as possible.
Remember, it has to be high enough to clear the height of the fuel
filler neck once the tank is on the ground.
Place a jack under the tank with a piece of wood (a 2 by 6 about a foot
long works good) between the jack and the tank. Just keep in place snug
without exerting so much pressure that the rear of the car starts
There are two straps that pivot from the rear
of the car and are bolted up to the floor in between the front of the
tank and the rear axle. Remove the two bolts in front of the tank and
lower the straps.
Using the jack, lower the tank about 8". Now the hard part: You will need pliers and a couple of wrenches, I
cant recall the sizes. Safety glasses are a good idea too to prevent
dirt from falling into your eyes. Crawl under the car towards the front
of the fuel tank and undo the fuel pressure line with the two wrenches.
Be careful not to damage the mating surfaces of the two unions. With
the pliers, depress the clips that secure the vent hose and the fuel
return hose and slide clips several inches down the rubber hose so that
you don't lose them. After that undo the rubber hoses from the steel
lines, if you think you might forget which hose goes on which line then
it is probably a good idea to label them.
fuel lines and hoses are no longer secure, lower the tank as far down
as you can while keeping the straps out of the way so that the tank
will slide out towards the back of the car. If not you will either have
to raise the front of the car to get it out the front or you will have
to undo the straps from the back of the car to get the straps
completely out of the way.
Slide jack out from under
the tank and allow it to gently drop the rest of the way. After
ensuring nothing is interfering or still attached, slide tank out from
under the car.
To reinstall, follow removal instructions in reverse order.
Never just drop the tank straight down. It must be lowered while
being pulled towards the rear of the car. If not you will bend the fuel
pump hardline that faces the Front of the car.
If your doing this to replace a fuel pump its also easy to just
cut away a little bit of metal around the cap where the sender
unit/fuel pump plugs go in, At most you need to cut only an inch or so
and can be done w/ a dremel.
This way you can remove it from the top, inside the trunk.
NOTE: Isn't there danger of spark when cutting metal with a dremel tool near the fuel lines?
There is , but the main line coming off the fuel pump is a hard line thats pretty thick.
If your worried about it, there is a drain that is very easy to get to on the underside.
Just use a little bit of cutting fluid to keep this cool if you want to...
that should stop the sparks from flying.
