The center fitting on the pump is for the vapor line. The large diameter fitting is the pressure line. The smaller diameter fitting is the low pressure line.

The Evaporative emission system has a large leak allowing fuel vapors to escape to the atmosphere . There are hoses an a purge solenoid ,a vent solenoid ,charcoal canister to store fuel vapors in . The charcoal canister is located under the vehicle near the fuel tank an has vapor lines running to the front of the vehicle to where the engine draws in the vapors by the engine computer opening the purge solenoid ! Any of this vapor hose could have a hole (leak) ,the gas cap could be lose or bad . The fuel filler neck could be rusted through ! At the repair shop we hook up a smoke machine to the system an look for a leak like that ! easy !

Raisethe trunk lid and access the fuel tank service cover in the upperright-hand side of the trunk ledge. Remove the cover and unplug theelectrical connector that powers the fuel pump. Start the carand let it run until the engine dies. This will remove thehigh-pressure fuel that is in the line so fuel will not spray when theline is disconnected. Test for voltage by probing the positive andnegative fuel pump wires with a test-light. Make sure there is avoltage signal to the pump. If there is, the pump is defective. Turnthe key off when the car stalls and replace the pump.
Disconnectthe fuel feed line with the quick disconnect feature that is part ofthe fuel line fitting. Squeeze the two tangs of the connector and pullthe hose off. Remove the fuel vapor hose that goes to the vaporcanister by loosening the clamp and pulling the hose off the vaporport. Remove the retainer ring that holds the pump assembly in placeusing a small shop hammer and screwdriver. Lightly tap the screwdriveragainst the indents on the retaining ring until it unscrews. (The ringlooks like a large lid that screws to a jar.) Completely loosen thering and remove the pump module by lifting it up and out.
Install a new pump module into the opening. The new module will comecomplete, including a new fuel filter. No parts will need to betransferred from the old pump module. Push the new module into the fueltank and tighten the retaining ring into place. Snap the fuel feed lineinto place, making sure there is a distinctive snap as the line locksin. Install the vapor line and tighten the hose clamp. Do not leavethis line off or fuel vapors will enter the car. Plug the wiringharness in, and replace the pump cover. Start the car.

    Service engine soon light came on, replaced gas cap it went off but a week later it came back on, when it try to fuel the truck it spill the gas back out like it is a full tank


    One of the most common causes, is blockage in the venting system from fuel entering the vent lines and into the charcoal canister, the fuel gets absorbed by the charcoal canister causing it to swell and block vent lines. the gas tank contains both fuel and air. when you fill it up the gas displaces the air and the air has to go somewhere. but the air that is displaced is full of gas vapor so the gas vapor goes to the vent lines and into the charcoal canister, when the charcoal canister swells up it prevents the air from escaping the tank, canister could be clogged,canister filter may need replacement,electrical connection to the close valve may be open,canisterf might be damaged,purge valve from canister might be clogged,vent hoses might be clogged, the vent hose could be clogged, or the vent hose may have a kink. all this is caused by overfilling the gas tank, getting that last drop of gas in the neck of the fill tube.
    good luck!

    When i go to start it for the first time it starts right up but after that it turns over for a long time before it starts someone told me it was charcoal filter on the return line do you think that is it i...


    When you had the fuel pressure tested did it hold pressure with the key off or did the pressure drop off?

    If it dropped off I would bet you have either a leaking fuel pressure regulator or a bad fuel pump. Fuel pressure needs to hold steady especially on a hot engine in order to prevent the fuel in the fuel rail from boil over.

    I think the 99 has the external injectors. If it does the fuel pressure regulator is located on the drivers side of the engine about in the middle of the fuel rail. There will be a small vacuum hose attached to it. remove the vacuum hose and see if gas comes out. If it does the regulator is bad. If it doesn't I would check the pump next.

    There is no charcoal filter on the return line or the pressure line. The charcoal canister is part of the evap emissions system and will rarely if ever effect the starting of the vehicle.

    Gas pump keeps tripping off often


    you have a bad charcoal canister. Go underneath the left rear of the car, pull the big hose off the charcoal canister, and if charcoal come out of the hose, replace the canister. This is a common problem w/Hyundai and Kia.

    Little Black Box, Fuel Pump, Fuel Lines


    it sounds like you have a line hooked up to the wrong spot, and that little black box sounds like the charcoal canister, which is used to filter out fuel vapors. it sounds like either the supply or return line has been hooked into the vapor line. retrace your steps, largest diameter line is supply, medium is return, smallest line is vapor line. good luck!

    I need to replace my fuel filter. need to know where it is and what i need to do to access it.


    Hi,

    Regarding Fuel Filter - Under vehicle, driver side, below seating area, front of fuel tank, mounted on chassis in fuel line.

    A device located in the fuel line to remove impurities from the fuel before it enters the carburetor or injector system.

    INSPECTION

    Fuel filters can be located in a fuel line, in the tank, in a carburetor, or in any combination of these. A carburetor often has a filter behind the fitting at its fuel inlet.

    An external fule filter. Courtesy of General Motors Corporation, Service Technology Group. Engine heat causes fuel to vaporize, which can result in vapor lock in the filter. Some fuel filters have vapor return lines to allow for expanding vapors and fuel to return to the tank.

    REPLACE

    Fuel filters and elements are serviced by replacement only. Some vehicle manufacturers recommend fuel filter replacement at 30,000 miles (48,000 km). Always replace the fuel filter at the vehicle manufacturer's recommended mileage.
    The fuel filter replacement procedure varies depending on the make and year of the vehicle and the type of fuel system. Always follow the filter replacement procedure in the appropriate service manual. The photo sequence below shows a typical procedure for relieving fuel pressure and removing a fuel filter.

    If the car is stalling it means that there is a problem in the fuel pump assembly where you have to check the fuel pump ,the fuel filter , the fuel lines.Prepare the tools or equipment to be used in checking or servicing the fuel pump assembly.In the fuel pump so that fuel pump will operate properly : locate the fuel pump,disconnect the fuel lines from the fuel pump,remove fuel pump from the engine,dis-assemble fuel pump,check the daiphram for defects, replace defective parts assemble and install fuel pump.
    in the fuel filter:So that when fuel filter is removed ,no fuel will spill on the vehicle and no parts are lost.Locate the fuel filter ,disconnect lines at fuel filter, observe safety practices . if the filter is worn out or dirty rather clean it or replace it and install new fuel filter.
    the fuel lines : So that fuel will flow freely and no abstraction within the fuel lines. Locate fuel lines, visual inspection on duel line for learage, disconnect lines at fuel pump and fuel tank, Use compress air to remove sediments on fuel lines re-install fuel lines to the unit. but if the fuel lines are worn out it should be replaced. If the owner of the car don't have time to service the fuel pump , the fuel lines ,the fuel filter . then the owner of the car should go to a car shop mechanic and let the car mechanic to do the job

    If you take the fuel return line off and it starts, it should spray some fuel out of the fitting the line slips onto. If not, you are either pulling the vaccum line or the pressure regulator is bad, or you could have a fuel pump going bad. One way to check the regulator is to apply vacuum to the port on the regulator and turn the key to "run" not start. With vacuum applied, fuel should run out of the return line fitting. If not, bad regulator or weak pump, maybey even a clogged fuel filter. If so, vacuum leak or blocked hose. Let me know if this helps :)
