Ok..

  • remove the negative battery terminal
  • open the gas lid and remove the tank cover.
  • under the car , under the gas tank is a drain valve , Its like a bolt)
  • connect a running hose and let water flow under the car, (optional)
  • get a large flat container
  • remove the drain valve from the tank and let the gas run out into the container. when its almost full cover back the valve, empty the container in a gas container an then continue to drain.

easier method but most people say its unsafe,

you need a hose and a gas container,

  1. pop the hood,
  2. locate the gas filter
  3. remove the hose leading to the gas filter, put it in your hose and place the other end in the gas container (ITS LIKE YOUR extending the hose to your gas container instead of the filter.
  4. turn on the ignition and watch the gas pump out the tank to your container, (pump must be working for this to work)

Two different procedures may be used to drain fuel
tank: through the fuel fill fitting on tank, or using a
scan tool.
The quickest draining procedure involves removing
the rubber fuel fill hose (7) (Fig. 25) from fuel tank
fitting.
As an alternative procedure, the electric fuel pump
may be activated allowing tank to be drained at fuel
rail connection. Refer to DRB scan tool for fuel pump
activation procedures. Before disconnecting fuel line
at fuel rail, release fuel pressure. Refer to the Fuel
System Pressure Release Procedure for procedures.
Attach end of special test hose tool number 6541,
6539, 6631 or 6923 at fuel rail disconnection (tool
number will depend on model and/or engine application).
Position opposite end of this hose tool to an
approved gasoline draining station. Activate fuel
pump and drain tank until empty.
If electric fuel pump is not operating, fuel must be
drained through fuel fill fitting at tank. Refer to following
procedures.
(1) Release fuel system pressure.
(2) Raise vehicle.
(3) If equipped, remove fuel tank skid plate.
(4) Thoroughly clean area around fuel fill fitting
(6) (Fig. 26) and rubber fuel fill hose (1) at side of
fuel tank. After cleaning, loosen fuel fill hose clamp
(2) at tank.
(5) Before removing rubber hose (1) (Fig. 26) from
fitting, note hose orientation while referring to marks
(3) and (4).
6) Disconnect rubber fuel fill hose at fuel tank fitting
(2) (Fig. 27). Using an approved gas holding
tank, drain fuel tank through this fitting.
Tank Removal
(1) If equipped, remove fuel tank skid plate and
tow hooks. Certain equipment packages will also
require removal of the trailer hitch. Refer to Tow
Hooks, Trailer Hitch or Skid Plate in 23, Body for
removal/installation procedures.
(2) Disconnect and separate fresh air tube (6) (Fig.
28) quick-connect fitting.
(3) Disconnect air tubes at front of NVLD pump
(9) (Fig. 28).
(4) Disconnect NVLD pump (9) (Fig. 28) electrical
connector.
(5) Disconnect fuel pump module electrical connector
jumper. This is located near front of fuel tank.
(6) Support tank with a hydraulic jack.
(7) Remove 4 fuel tank strap bolts (10) (Fig. 28) (2
at front of tank; 2 at rear of tank), and remove both
tank support straps.
(8) Carefully lower tank a few inches.
(9) Continue lowering tank while guiding remaining
hoses and lines through plastic isolator sleeve (3)
(Fig. 29).
(10) If fuel tank is to be replaced, remove NVLD
pump and fuel pump module from tank. Refer to
Fuel Pump Module Removal/Installation procedures.
end , tank out.

Have water in fuel Suzuki xl7 how do I drain the tank


no year, huh? some years have a check valve , there,....
this forum is for usa cars, is car USA car?
the tanks just dont like siphoning. (check valve)
the FSM covers this , in the fuel section under bad pump.
1998 to 2006, ill guess, 06

i have the FSM and does not cover. bad fuel, no drain plug.

it shows how to get fuel lower, in filler neck
the tank has check valve at it its metal neck.
so inserting a hose in filler, will hit this check valve.
and all you get out , is 1/2 fuel.
id use the tank out procedure.
then empty all fuel, after step 5.
quote:
  1. Disconnect the negative battery cable.
  2. Relieve fuel pressure in fuel feed line.
  3. Due to absence of fuel tank drain plug, drain fuel tank by pumping fuel out through fuel tank filler.
  4. Use hand operated pump device to drain fuel tank.
  5. Remove fuel tank.

tip tank to drain the remainder. out

here is one more way. (IDEA!)
do 1-4
then tip car to left. Jacks then stands at frame.
then remove the filler hose on tank
remove that pesky check valve. from neck last.

and pump out the rest.

My nissan navara keeps loosing power while iam driving if i come off d accelarater and mash again d power comes back den it happen again and again


sounds like the bearings in your fuel pump are going. These bearing are undoubtedly not replaceable without replacing the entire fuel pump.

Fix: replace fuel pump.
Difficulty of fix: moderately advanced. You have to jack up car, drain the tank at the fuel tank drain
and then disconnect fuel lines (3), unbolt the (always rusty) bolts holding the tank, then go at the fuel pump replacement procedure, remembering to replace the fuel pump gasket.

If your car has a hatch in the top of the tank for fuel pump replacement (Hondas do), then use that access to get to the part - otherwise pull the gas tank and replace it that way, While you're in there, replace fuel filter(s) and strainer too (as a matter of course).

If the problem were clogged fuel filter, you'd experience loss of power going uphill, and it would not be able to made to "come back" by mashing on the gas pedal.
