Where is the fuel tank drain plug?

Fuel tanks do not have drain plugs ,if you can't siphon the gas you could use the vehicles own fuel pump to drain the tank . Find the fuel pump relay in the under hood fuse / relay box . Jumper where the relay plugs into it. Disconnect fuel line at the engine an drain into a gas cans .

I have never seen a tank with a plug. If you need to drain the tank, you can buy a siphon kit. Do not try to suck the gas out. Even the fumes can destroy your lungs

2 ways. Just assuming you have no bottom drain plug, you can remove the filler hose and stick a siphon hose into the tank, and siphon out almost all of the gas that way. Or you can get creative and throw battery power to the fuel pump and let the pump empty the tank for you. I think you could do it at the fuel pump relay.

the FSM book covers this. (ill do the full tank pull... as you never said the JOB!)
its siphoned to near empty. (use a hand pump for fuel , sold at all boat center)
do you need the FSM page quotes?
on some cars there is an anti-spill roll over check valve
at tank fill port making siphoning very hard.
my answers are USA cars, on this USA forum.... and swifts vary big time world wide..... dig?

quoted. (no smoking no open flames, outdoors best. no shop heaters of ANY KIND near)
"tank pull steps. (sure drained)

1. Before servicing the vehicle, refer to the Precautions section.
2. Relieve the pressure from the fuel system. (in the FSM)
   
3. Disconnect the negative battery cable.
4. Remove rear seat cushion.
5. Disconnect connectors of fuel tank wire harness.
6. Hoist vehicle.
7. Disconnect fuel tank filler hose and breather hose from filler neck.
8. As fuel tank has no drain plug, drain fuel tank by pumping fuel out through fuel tank filler or fuel tank inlet. Use hand operated pump to drain fuel tank.
9. 1. Disconnect fuel pipe joints and fuel hose from pipes. For quick joint, disconnect it as follows:
      
      • Remove mud, dust and/or foreign material between pipe and joint by blowing compressed air.
      • Unlock joint lock by inserting special tool (part No. 09919-47020) between pipe and joint.
      • Disconnect joint from pipe.
   2. Remove fuel tank from vehicle.

Most tanks have no drain plug due to safety regulations the only way is to remove the tank and drain it from the top

Yes some models had a drain plug on the passenger side towards the front of the tank 17mm plug or 14mm. these cars also have a access panel to remove fuel sender or fuel pump with out dropping tank panels are under rear seat . remove and use Oklahoma credit card to siphon out the fuel.

No, unfortunately there is no drain plug in the fuel tank. if you need to remove the fuel from the tank, you will want to use a fuel siphon.

Modern cars can't be SIPHONED anymore! U go under ur car and drain the FUEL from the tank drain plug!
Taah!

The easiest way to drain the fuel is to siphon the fuel from the tank through a small polypropylene hose inserted down the filler port. Be careful to push the metallic flap aside when inserting and removing the siphon hose, a small screwdriver with a large handle should work fine (so you can't drop the screwdriver into the gast tank). The only other way will be to drop the gas tank, but they recommend siphoning the gas out before you actually remove the gas tank straps. You will also need to disconnect the battery cables before you drop the tank to avoid any sparks from the wire connections.

most gas tanks don't have a drain plug.can eith try siphoning it out with a hose called a magic siphoning hose or disconnect the fuel line and put the line in a container to catch the bad gas.

other option is to drop the fuel tank and empty
