    Do you mean gasoline is coming out of the filler tube for the gasoline at the gas cap?

Why is my gas tank spitting gas back at me?


There\'s a blockage in the secondary tube (about 15mm diameter) that runs down to the tank, adjacent to the main filler tube. Take the back wheel off and you\'ll see a plastic cover over the whole filler neck assembly. The secondary tube often rust and fills with dirt. The tube can get damaged too, if crushed the gas will spit back.

Gas pump shuts off like its full many times while trying to refuel.


Usually a blockage in the filler tube or a vent problem.
You may have to take the filler tube off and inspect it. There should be a tube inside or outside the pipe to allow air pressure in the tank to equalize.

2004 mercury sable gas go's into tank real slow


This is caused by an obstructed filler air pipe vent, this keeps the air from coming out of the tank as you fill, this causes the filler nozzle at the station to shut off as the gas backs up in the filler pipe, the air vent pipe is either kinked or blocked in some way. The vent tube runs down along side the gas fill tube and is all one part, replace it.

F-150 ford truck check engine light keeps coming on


Did you replace the gas cap? Also check the filler tube that's where the gas cap snaps on where you put gas in. The filler tube or neck has a thin lining of plastic at the top look for small cracks in it where the gas cap goes on. It there's cracks in it, it will cause an emission leak and sometimes a dealer won't find it until you spent a lot of money on diagnostics. And it depends if there best mechanic was working on it.

Check engine light is on for emission evaporator failure-large


P0455 - EVAP Control System Leak Detected (No Purge Flow or Large Leak) The PCM monitors the complete EVAP control system for no purge flow, the presence of a large fuel vapor leak or multiple small fuel vapor leaks. The system failure occurs when no purge flow (attributed to fuel vapor blockages or restrictions), a large fuel vapor leak or multiple fuel vapor leaks are detected by the EVAP running loss monitor test with the engine running (but not at idle).
  • After-market EVAP hardware (such as fuel filler cap) non-conforming to required specifications
  • Disconnected or cracked fuel EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube
  • EVAP canister purge valve stuck closed
  • Damaged EVAP canister
  • Damaged or missing fuel filler cap
  • Insufficient fuel filler cap installation
  • Loose fuel vapor hose/tube connections to EVAP system components
  • Blockages or restrictions in fuel vapor hoses/tubes (items also listed under disconnections or cracks)
  • Fuel vapor control valve tube assembly or fuel vapor vent valve assembly blocked
  • Canister vent (CV) solenoid stuck open
  • Mechanically inoperative fuel tank pressure (FTP) sensor
Check for audible vacuum noise or significant fuel odor in the engine compartment or near the EVAP canister and fuel tank. ----------------------------------------------------------------------------- HX43 DTC P0457: CHECK FOR MISSING OR LEAKING FUEL FILLER CAP
  • Check for missing fuel filler cap.
  • Check for loose fuel filler cap.
  • Check for possible cross-thread fuel filler cap condition.
Is a fault present concerning the proper installation of the fuel filler cap? Yes No REPLACE cross-threaded or damaged fuel filler cap. RECONNECT and TIGHTEN the fuel filler cap only one eighth turn so that the cap initially clicks by sound or touch. CLEAR Continuous Memory DTCs. COMPLETE an Evaporative Emission Running Loss Monitor Repair Verification Drive Cycle (refer to Section 2 , Drive Cycles). RERUN Quick Test . If DTC P0455 or P0457 is present, Go to HX44 . CLEAR Continuous Memory DTCs. COMPLETE an Evaporative Emission Running Loss Monitor Repair Verification Drive Cycle (refer to Section 2 , Drive Cycles). RERUN Quick Test .

For DTC P0455 still present: Go to HX44 .

Otherwise, INFORM the vehicle owner that it is important and necessary to immediately install the fuel filler cap after every refueling event. HX44 DTC P0455: VISUAL INSPECTION FOR SUBSTANTIAL EVAPORATIVE EMISSION SYSTEM LEAKS
  • Check for missing fuel filler cap. If the cap is loose DO NOT DISTURB EVAP system.
  • Verify that both the input port vacuum hose and EVAP return tube are attached to the EVAP canister purge valve. Note: If the EVAP canister-CV solenoid assembly is not accessible during this pinpoint test step, GO to Evaporative Emissions, Section 303-13 in the Workshop Manual for removal and installation instructions.
  • Verify that the CV solenoid is properly seated on the EVAP canister (if possible).
  • Visually inspect for disconnected or cracked fuel vapor hoses/tubes between the intake manifold, the EVAP canister purge valve, the EVAP canister, the fuel vapor vent valve assembly and if applicable the fuel vapor control valve tube assembly.
  • Check for damage to the fuel filler pipe and the fuel tank.
Is a fault indicated? Yes No CONNECT or REPLACE fuel vapor hoses/tubes as required. REPLACE damaged EVAP system components (fuel filler pipe, fuel vapor vent valve assembly, fuel vapor control valve tube assembly, EVAP canister purge valve, FTP sensor and EVAP canister-CV solenoid assembly) as necessary. REFER to Evaporative Emissions, Section 303-13 in the Workshop Manual for removal and installation instructions. GO to HX45 . GO to HX45 . HX45 DTC P1443 and P0455: CHECK FOR EVAPORATIVE EMISSION SYSTEM LEAKS
    Note: When checking for leaks or blockages in the EVAP system, energize (close) the canister vent (CV) solenoid through the scan tool for a maximum of nine minutes per pinpoint test step. Then de-energize the CV solenoid prior to performing the subsequent pinpoint test step. This is done to assure proper closing of the solenoid.
  • Disconnect and plug the EVAP return tube (EVAP canister purge valve to intake manifold) at the intake manifold vacuum source.
  • Connect scan tool.
  • Key on, engine off.
  • Access VPWR PID. If the voltage is not 12 volts or greater, GO to HX61 .
  • Locate evaporative test port [marked EVAPORATIVE SERVICE PORT DO NOT USE UNREGULATED PRESSURE ABOVE 6.89 kPa (1 PSI)] near EVAP canister purge valve or EVAP canister.
  • If vehicle is not equipped with the evaporative test port, GO to HX50 .
  • Install the Rotunda Evaporative Emission System Leak Tester 310-F007 (134-00056) or equivalent at the evaporative test port.
  • Close CV solenoid by accessing Output Test Mode on the scan tool.
  • Select ALL OFF mode and push START button.
  • Regulate the nitrogen or argon gas pressure on the tester to 3.48 kPa (14 in-H 2 O).
  • Follow the instructions that come with the EVAP System Leak Tester and pressurize the EVAP system.
  • Perform the EVAP system leak test.
Does the pressure on the EVAP system stay above 1.99 kPa (8 in-H 2 O) and pass the leak test? Yes No GO to HX46 . REMOVE the EVAP System Leak Tester from the evaporative test port and REINSTALL the test port cap. GO to HX50 .

1999 chev. lumina emissions test (trouble codes p0442 & p0446 )


replace gas cap but first check for rust around rim of filler tube where gas cap makes contact with tube. if there is rust clean it off and replace the cap.then you need to clear the code in the computer to see if this was the problem.. corrosion on the filler tube will cause a small lesk in the evaporative system which corresponds to the 442 code

Strong gas smell inside and outside


On my 2002 I had the same problem and was caused by the evap system (emissions). The module is located in the back of the car, tucked up right by the back fender-pannel by the fuel filler tube.
