Anyone else experience this?
 
First of all I am from a state with gas attendants so I cant pump my own gas, I am not sure what is causing it but each time I stop at a gas station and someone goes to fill the truck, The nozzle clicks off and kicks a bunch of gas out of the tank and all over the concrete. Is there a way to fix this problem? Has any one else had this issue. Its a 2002 2.3.

What you have is a clogged Vent hose for the filler tube, happens to any vehicle

From the side of the bed to the gas tank is the Filler hose, next to it is the smaller Vent hose
Vent hose allows air OUT of the tank while gas flows IN to the tank
If air can't get out then gas backs up in filler hose and comes out

You will have to look at vent hose and see if there is a clink in the rubber part of the hose.

Thanks, I'll look into it! It wasn't just a little gas, it was a lot.

Fill a clear bottle, with smaller opening, with water, like a store bought water bottle
Flip bottle upside down

Watch the top of water in the bottle as the air comes in, lots of splash back

Filler tube without a Vent is the same as the water bottle, tube gets full of gasoline and the air MUST come out, so up she comes and splash back can be pretty big

If you slowly fill the tank then air can come out of filler tube as gas goes in, until Vent hose issue is solved

I took a look underneath and had the guys at jiffy lube take a look and let me underneath. There is no kinks and everything looks good. Someone told me a possible fuel filter problem?

Nope, not a fuel filter issue, only plugged up vent can cause that, or partially blocked filler tube

For several years, ORVR (Onboard Refueling Vapor Recovery) has been required by the EPA. Instead of belching a lot of unburned hydrocarbons from the filler neck during refueling events, this system vents most of those vapors through a larger carbon canister where the hydrocarbons are captured and stored for burning later.

If the vapor path from the tank through the canister to atmosphere is restricted, the tank will be difficult to refuel because the fuel filler neck is considerably smaller than it was before ORVR was introduced. The idea is to completely fill the smaller diameter neck with fuel and force the vapors through the canister instead. Stop the vapor flow through the canister and refueling becomes stop and go.

There is a step-by-step troubleshooting procedure in the factory shop manual for poor filling on ORVR equipped vehicles. Cars got ORVR phase in during 98-00MY, light trucks starting in 2001MY.

Here's a generic diagram of a Ford ORVR system:

The EVAP system should generate a code if atmosphere valve wasn't opening during test, it runs tests all the time.

Also the EVAP only does partial vapor recovery, EVAP hoses are just too small which is why there is still the Vent hose on the filler.
Surprised it shows it on the drawing, shouldn't be there if EVAP could handle all the out flowing air during refueling.

But in any case, if visual inspection doesn't show kink or blockage, then you will have to go farther to find the reason for "slow fill" issue, which means lifting off the bed.
When you lift the bed off you can test the vent solenoids and EVAP system for problems
Andin this case you do want to lift off the bed not lower the tank
