Default gas tank wont fill fast

is this covered by a service bulletin or a recall anyone know for sure?

1999 accent ,I can fill up fast or the nozzel shuts off ,this is what they claim to check on it but I dont have a clue where to start
Common blockage issues are with the canister close valve and the canister filter. But you could also have a defective fuel cut valve in the tank or a blocked canister. You could also have a problem with a restricted hose or pipe either not allowing proper venting or not allowing the fuel to enter the tank properly."

<div class='quotetop'>QUOTE(http://hmaservice.com/local_viewer/t...?title_num=331)</div><div class='quotemain'>general diagnostic procedures: hard-to-fill fuel tank
DESCRIPTION

All 1999 and later Hyundai vehicles incorporate a new emission control system known as On-Board Refueling Vapor Recovery (ORVR). A general schematic of the system is provided below.

Some owners may experience difficulty filling their vehicle with gasoline and a premature shut off condition as a result of the gas pump nozzles installed at their gas stations. The nozzles at these stations are in the process of being retrofitted or replaced by the nozzle manufacturers. In the meantime, owners should follow instructions posted near the gas pump, and/or try filling the vehicle at a different gas station.

If the refueling difficulty continues, verify that the 1/2" vapor path from the fill vent valve on the gas tank to the air filter on the charcoal canister (see schematic below) is completely
free and clear. To perform the procedure below, make sure the fuel tank is below 1/4 tank full.

To quickly determine the general location of a possible vapor path restriction:

* Disconnect the hose connected to the canister side of the liquid-vapor separator (see schematic below).

* Take the vehicle to a known "good" or major brand gas station.
o
If the vehicle readily accepts fuel, the restriction is located between the liquid vapor separator and the air filter.
o
If the vehicle does not easily accept fuel, the restriction is located between the liquid vapor separator and the fuel tank.

On-Board Refueling Vapor Recovery (ORVR) Schematic

The following components are contained in the ORVR system:

*
Vapor hoses
*
Liquid-Vapor Separator(s)
*
Fuel Fill Vent Valve
*
Fuel Cut Valve (anti-spitback)
*
Canister Close Valve
*
Air Filter
*
Charcoal Canister

[Click for zoom window]

After the restriction has been isolated to either half of the system, inspect each component to make sure it is free and clear of any restrictions. Verify that no
back pressure can be felt anywhere between the fill vent valve and the air filter at the canister.
NOTE
1999 Accents have two (2) liquid vapor separators: one located on top of the fuel tank, the other located alongside the filler neck.
[Click for zoom window]

When checking the liquid vapor separator, blow through one end of the pipe using lung power. NO
back pressure should be felt.

Verify that the Fill Vent Valve is open by carefully removing the valve and confirming that the white plastic shut-off plunger moves freely inside its cage.
[Click for zoom window]

If the fuel cut valve plunger is stuck closed, a hard-to-fill condition may result. Verify that the plunger moves up and down freely allowing fuel to enter the tank, but does not allow fuel to travel up the neck (under pressure). The plunger should be "up" (closed) in its free state.
[Click for zoom window]
IMPORTANT
When working with the Fill Vent Valve and associated plumbing, be sure to replace the hoses into the proper hose clips to prevent fuel from getting trapped / puddled in the vapor hose. Return fuel from the liquid-vapor separator must have a clear path to drain back to the tank.
Four Way Valve

Purpose:
The Four Way Valve provides an additional vapor path to the canister during refueling.
[Click for zoom window]
NOTE
1999 Sonatas have a Four Way Valve located between the liquid vapor separator and fuel tank.

Proper operation of the valve is as follows:

1.
Air flows freely in either direction through the 1/2" ports.
2.
Air flows freely in either direction through the 1/4" ports.
3.
Air flows from 1/2" port to the 1/4" port when blowing into one of the 1/2" ports while plugging the other 1/2" port.
4.
Air does not
flow from 1/4" port to the 1/2" port when blowing into one of the 1/4" ports while plugging the other 1/4" port.

no, it's the site's copy and paste system. Sorry. Some sites let you copy and paste a TSB, here it does not let you dynamically link images.

Let me go through and pull up the individual images
