The small hose is a vent line that is put in place to do just that vent the fuel, many times fuel will back feed out the vent line when it is very hot outside due to expansion of the gases, also if you have a kink in the fuel fill line going into the fuel tank, if you can't physically see the kink you may have to have the tank dropped for a closer look especially if someone else was in the tank to repair something like the fuel pump etc. once before. it is possible they forced the fuel filler line into the tank without realizing they caused the "kinked line" situation, perhaps the fuel tank was damaged from an accident as well causing all these problems, look for anything that appears to be unusual such as dents, kinked lines, perhaps the fuel tank hanger straps were jarred and the fuel tank was moved into a wrongful fit under the vehicle.

The hose is on the side of the gas cap and it runs down to the bottom of the quarter panel. When I filled the gas tank up, gas comes out of this hose. We just had the fuel pump replaced. Its not leaking...

There are normally two hose lines from the fuel filler that run to the tank. The larger one carries the fuel from the nozzle to the tank. The smaller one is a vent hose that allows vapors to leave the top of the tank while filling. These vapors come back to the nozzle area and can be vented and/or collected by the nozzle depending upon air pollution standards in your area. If your second hose is running to the bottom of the quarter panel, it is probably the vent hose that may not have been reconnected at the top of the tank when the fuel pump was replaced. The fuel running down there is from kickback fuel at the time the pump shuts off. The real problem is that the vent line is open on top of the tank and when the tank is full, that can allow vapors and fuel to escape out of there and it could contact hot exhaust areas - a major fire or explosion hazard. Have this inspected and repaired IMMEDIATELY.

1996 dodge dakota, used bad fuel, won't start

Pump the tank dry of the fuel using the electric fuel pump, just jump the fuel pump relay to get the pump to run and remove the supply line to the injectors and attach a hose. Use extreme caution around gasoline, no sparks, ground the container to the truck.

How to drain a2005 f 150 gas tank, bad fuel

The best way to drain the tank would be by removing the filler neck hose going to the tank and then using a small hose to insert into the tank going into the neck.the reason for a small hose or a piece of metal line like a brake line and then slide a long piece of rubber hose over the line about one foot and clamp it tight to line,the next step is to one; put a slice or small cut about 3 inches from the end of the rubber hose and if you have an air nozzle push it into cut on line and blow air into it, this will make vacuum and fuel will start to flow out of hose.
With out an air nozzle you will have to **** on end of hose to get it to flow,CAUTION DONT GET GAS IN MOUTH!!!!!.With the metal line you will need to get it past the ball in the neck of tank, this is the reason i said to use a small metal line, you will need to bend it and move around to get past ball. slide into tank to hit bottom. DONT MARK SPARKS!!,
The other way is to drop tank and remove the fuel pump assm and then drain threw the top hole that pump sits into. hope this is helpful. good day.

2000 Ford Taurus. Would fill up with gas when close to empty or light come on. Then a couple weeks ago,gas gauge was on 1/4 tank then went a little lower and engine started bucking. Then light came on. ...

change the fuel filter for one, this is telling you that your pick up in the tank is getting clogged, I would drop my tank, and drain it, flush it, and check the pump at that time

pull the nossle out a little and it should work better. try a different station. the older nossles took more to shut off but ocationaly caused a spill so they make them more sensitinve. inside the nossle is a small float. if u put gas in too fast some times u get gas bubbling back up the small hose from your tank thats made to let vapor out. if it does u will hit the float and shut it off. its probly more the nossle then the car. although it does depend on the car as to how fast u can put gas in. next time u put gas in look in there after u take off the cap you will see a little spring loaded flap. put the nossle in just a little bit past that. not all the way in. this usualy helps. and like i said u can also try a different gas station to find out if its the nossle or just simple that the car wont take gas that fast. i have had that problem at some stations where i cant even get it to stay on on the slowest notch. hope this helps.

Gas Tank starts to overflow on empty? I tried all different nozzle positions. But the gasoline still backs up?

The rubber hose that runs from the gas cap down to the tank has a smaller hose inside it. The gas goes down inside the smaller hose and the air comes up around the small hose and vents at the gas cap. It sounds like one or both hoses have become crimped somewhere. I wonder if maybe you have hit something like a parking lot curb or had a really hard thump near the gas cap. Crawl under your car and look for the gas tank filler hose. I think you will find the hose bent or collapsed between the cap and the tank. Replacing the filler hose is not difficult but can be frustrating. You may have to lower the tank to get enough clearance to remove the old hose and install the new one. The other suggestion is to see if your gas gauge is working properly. Is it possible that the tank is full and the gauge shows empty? Let me know what you find out.

Where is the evaporator hose

if you mean the evaporator hose for the air conditioner .. then observe under the hood .. you will see two pipes coming from inside the car side by side .. one is large and one is small .. the evaporator is the thing inside your heater compartment that cools the air for air conditioning .. the hoses could be called the "evaporator hoses" . the large hose is the "low pressure" side and is where the refrigerant comes out of the evaporator .. the smaller hose is the high pressure side and thats where fluid under high pressure enters the evaporator

now there is also an evaporitive emission control system on your car .. thats where gas fumes that evaporate inside the gas tank are collected in a charcoal cannister temporarily .. when the car is running those fumes are drawn into the engine and burned along with the fuel ... there is a hose that comes from the gas tank to the cannister and you could call that an evaporation collection hose ..

2001 hyundai accent, trouble filling gas tank

I have 2002 Hyundai Accent. When fueling, I had to trickle the fuel in to prevent the fuel dispenser from constantly shutting off. Even then I could only get about a quarter gallon at a time between fuel shutoffs. Would take 10-15 minutes to put in 10 gallons. Very frustrating. I found and fixed the problem today. There is a charcoal cannister that is part of the Evaporative Emissions control system. It is located inside the rear fender well on the driver side, behind the driver side rear tire. You cant miss it. Actually looks like a square plastic box and it has hoses coming out of it. I removed the entire charcoal cannister assembly in about 15 minutes. Follow carefully. First, remove the electrical connector to the purge control valve (this valve assemby is mounted to the side of the charoal cannister on a bracket). No big deal. Then disconnect the three hoses that come out from the cannister assembly on the one side that faces the rear tire. Two of these hoses are small diameter about 1/4" and one is larger at about 5/8 inch diameter. Then you remove the 3 bolts that hold the whole cannister to the car frame. Then the whole piece comes out. Once I got the cannister and purge control valve out of the car as a whole assy I found the problem. The larger of the 3 hoses you disconnected as well as the port it connects to on the cannister was packed with the small charcoal pellets and actually formed a solid plug inside that larger hose. I had to stick a screw driver through that hose to knock the plug out that those charcoal pellets had formed. It all makes sense now. When you fill the tank with gas, you also push out air and vapor from the gas tank that is being displaced by the rising fuel in the tank. That vapor is supposed to go through that larger hose to the charcoal cannister where the fumes are removed by the charcoal. If that hose is plugged, like mine was, then the vapor has nowhere to go as you fill the tank and it increases pressure within the tank it causes the fuel dispenser nozzle to shutoff because it keeps detecting a pressure increase within the tank. That's my theory. I don't have the Hyundai design prints to confirm it. I had to tilt the charcoal dispenser so that the pellets came out of that larger hose port on the cannister. Like I said, even the port itself was full of pellets. So I poured out enough to clear the pellets that were in the hose port. I cleaned out the hose. Put everything back and went to go fill with gas. I filled that tank at full bore with no problem. Have the dealer or your mechanic check the ports and the hoses off the cannister. If they are filled with charcoal pellets, that is the problem. That should cost less than some of the fixes I have been reading about here.

Car Turned off LIke it Was out of gas...

You should be able to hear the fuel pump running after cranking it enough to build up some oil pressure.
If the pump does run......try adding some fuel.

Fuel tank won't accept gas

In the 2000 Impala, there is a small filter located in the driver's rear quarter panel that is supposed to permit some air to move to adn from the fuel tank to account for expansion and contraction of the fuel, and provide a path for the displaced air while fueling. When this filter gets clogged, the air cannot vacate the tank during fueling, and the pressure causes the pump to click off.

To find it, underneath the vehicle, trace a hose from the top of the tank to the space on the driver's side behind the rear wheel. It will be a small plastic black box about 1" x 3' x 3'. Carefully remove, and open it, and the filter may be replaced or cleaned depending on your budget.

I have seen this on an Impala and a Cavalier, the part is identical.
