Fuel won't go in without shutting off pump multiple times

[firedoc]

I hope this is the correct place for this, but I trust you guys.
My daughter has an 04 Yukon XL as her tow vehicle. It has started to become a problem to refuel it. It probably takes her 20 minutes to fill it up because the pump keeps shutting off. She keeps getting embarressed when aguy comes over to "help her out" (after all she's only a woman) and can't do any better. Doesn't matter what pump she uses or how she puts the nozzle in. I'm thinking its something to do with the vapor recovery system or vent in the fill neck, but don't know what to do.
Anybody?

I have an 04' Yukon XL and experience the same issues at times. We are in CA with the vapor recovery system which adds to the problem in my opinion. Here is my solution that works 95% of the time: Hold the handle as centered as possible and lift it as high as you can making sure it is still sealed. So in other words, push the handle up toward the window. It also helps to go less than full power. Some stations/pumps are worse and I give up. But try my way and it should help.

This is a pick up? If so I can not assist you much save to recomment you choose your pump carefully. You want to tilt "Away" from the pump..

On pick ups however this should NOT be a problem.. on motor homes it is a major one.

It has nothing to do with the evap control system. The vent tube that allows the vapor to escape the tank during filling may be the problem. Had that with my daughters plymouth.

Check (google) online for any recalls and TSBs (technical service bulletins) relating to this.

Its NOT supposed to be a problem.

Every vehicle has a vent hose to allow air to escape when the tank is being filled with fuel. I submit that somewhere that fuel vent hose is either blocked or kinked enough to prevent the air from venting. You should be able to see the top vent point just inside the filler opening. This hose runs from the top of the tank, where the fuel hoses are located, to about 1" from the filler opening. Removing the hose at the top end is simple, not so easy from the top of the tank, as the tank usually has to be removed from the vehicle to access the hose connections and to replace the fuel filter.

I've had this problem in the past as well and this was EXACTLY the fix for me. It worked better while using a slower setting, and it works best if you stand there and hold it into that position (up towards the window). One thing I tried that worked (if you don't want to be stuck holding it): push it in as far as it will go and give it a slight nudge up or down to get it to stay in deep, then put it on the slowest setting. If this works (it seems to be hit or miss), it will take a while but at least you don't have to hold it. I use that time to thoroughly clean the windows on my "bus" (Suburban).

Inside the fill hose, down by the tank, is a valve called a "roll over valve".

It is supposed to prevent the fuel from leaking out of the tank in case of a roll over in an accident. Pehaps yours is malfunctioning.

From the factory manual:

A typical EVAP system consists of the following components: * EVAP Charcoal Canister * EVAP Canister Purge Valve * EVAP Canister Vent Valve * EVAP Service Port (has a green cap) * EVAP Vapor Vent Pipe * Fuel Fill Neck/Fill Cap * Fuel Tank * ROLL OVER VALVE with integral Fuel Pressure Sensor (FTP) * Vent Hose/Pipe * EVAP Vapor Pipe

Many newer vehicles dont have a vent tube. they are vented thru the evap system. check your filler tube, if it is a small single tube, you dont have filler vent. this is to keep fuel fumes in the system and not going to atmosphere when refuelling.

I had a vehicle that did that, I don't know why but I found a work around. On most gas pumps you can kill the vapor switch on the pump by pulling the rubber on the pump nozel up as far as you can to expose as much nozzel as possible, then just shoot the gas down your gas tank tube. Most pumps worked fine when I did this but some didn't. Give it a try, it's easy and should work at most stations. It's defeating the purpose of the vaccum system but if you need gas, you need gas.
