My 2500 4x4 AV had the TSB for the slow to fill and difficult to fill the last 6.5 gal done a few weeks ago. It helped, but never really fixed the problem.

I don't notice the problem at the 6.5 to go point so much any more, but it is still very slow to fill.

The station that I go to uses vapor recovery nozzels (not required here in Nevada like in California). Anything but the slowest setting and the pump clicks off.

While the AC is being worked on, they are going to check the fuel system again too. I'll let you know how it turns out. Seems like a vent problem to me.

Cheers - Jim
 
Jim,

I have a 2500 4X4 also and had the same problem. I had the mod done last week and have only filled up once since then and it seemed better. I found that turning the fuel nozzle counter clock wize helped. I find it to be a minor annoyance. You will probably just have to burp it occasionally anyway..

I have not had the mod, have found that just holding the hose up in the air a bit does the trick, aims the end of the nozzle right down the throat. ;D
 
I forgot one thing also..This problem seems to have only affected the earlier 2500's mine was born 09/01 a buddy has a 2500 born 12/01 and does not have the fueling difficulty.

My 2500 was born on Jan of 02 and has had the refuel problem since I picked it up in Feb of 02. I have tried all the positions I can think of (execpt standing on my head) for the nozzle, and still the pump clicks off at anything above the slowest fill rate and even then the pump will click-off every gallon or so. Hate spending 15 minutes putting fuel in. I'll post what the dealer does this time with I get it back (tonight or tomorrow). Cheers - Jim
 
The dealer just called - said they are ordering a new fuel tank and filler. I thought they already did last time it was in, but I guess not. The parts will not be in until Friday, so I guess I will be driving the Vette for a couple more days. Cheers - Jim

Man, forced to drive a Vette during the Spring! Life can be sooo unfair! >:D
 
The TSB stated that the main part of the fix was to replace the filler neck hose. If they are going to install a new fuel tank then hopefully that will solve the problem.
let us know how the new tank works. Be sure you get the vehicle back with the same amount or more fuel in the tank.
 
Ditto on the filling problem. It seems the dividing line is 09/01 and 10/01. I've had my truck into the dealer many times before the TSB and they always said "Not Repro." I was the one who brought the TSB info to them (thanks to this web site and all the great people).

I had the new filler neck installed in April. Didn't fix the problem. They said they'd talk with Mother Chevy and let me know. I call the service agent every month. Still no answer. Well, I was in there today for some other warrantee stuff. Still no resolution.

Other people have mentioned that certain gas stations are better than others. I know of ONE pump at one station where I can fill the truck all the way on the first try. Otherwise, I fill as far as I can, drive a little, fill some more, drive...repeat until really full. The only way to fill the tank before a long trip.

I still say the aux tank isn't draining fast enough into the main tank.

Keep us updated!

Mine is a 7/01 and has a minor problem but nothing like some of you are describing, I just hold the hose and go - strange. ;D
 
???Lucky i guess, mine usually shuts off, and then after rocking it back and forth, then put the cap on and roll it with my knee back and forth i usually end up getting about 3.5 more gallons in it. Then the fuel is sitting filled to the top. I fill up so often this is the only way i can get good mileage readings. Get strange looks..............Oh well get those driving down the road too...........
zeeya :2:
 
Hey gandolphxx , I was not aware that the 2500 was available that early in the year.. I got the first 2500 delivered to my dealer in So Calif. Born 9/01. They must have hit other parts of the US well before they made it to California..


Gary
 
I had a similar problem when I owned a K1500 Blazer that I had an oversized gas take made for it.

The &*^!! refused to fill plus the nozzle kept "unclicking".

Back to the installer. It seems that they used the old tank vent line which was smaller than it needed to be. When you are filling the tank at high speed the gas fills up the filler neck and either the nozzle unclicks or it stops before it is totally filled.

Bigger vent line solved the problem.

Also, kink or bend in the line will also cause problems.

Texas was one of the early deliver states, this was the only one in town that I spotted, large dealership, they had it up on the porch and the salespeople slept in it. >:D
 
I have a friend at the dealer and he checked all the AV's on order and they had 3 2500's coming in the first batch. 1 white and 2 black. I went with the white. as it had all the options that I was looking for.

I hope your not expecting pity or anything. Gee...how terrible....your forced to drive the Vette a few more days. :D :D :D

I hate it when I'm forced to drive my '62 Thunderbird for a few days. People really feel for me. :D :D :D
 
Hope to pick up my AV from the dealer today - kind of overcast and not so hot here in Vegas today (only 90 at 10:30 am). Maybe I'll put the top down on my little red chevy...Cheers, Jim

My 2500 was born in 1/02. I have had experienced the same fueling problems, but not at every gas station. I am convinced that it depends on some variable that some stations have, and others do not. We have a BJ's here (similar to a Sam's Club) and I do not have a problem with fueling there. I can go down the road to the next gas station and spend 10 minutes trying to get fuel in the truck. Maybe vapor recovery at some stations and not others??? Who knows....
 
I had a Jeep Wrangler that either came with a 15 or 20 gallon tank. It was later learned that the tanks were the same but the vent hose was deeper into the tank on the 15 gal. tank causing the fuel nozzle to shut off sooner. Did Chevy do this with the 1500 and 2500 AVs ??? And were some of the 2500s were shipped with the wrong "tank"?
 
No the 2500 Av has and extra 6.5 gal tank on top of the 1500s 31 gal tonk for a total of 37.5 gal. I can get 37.5 gal in, it just takes a long time, esp at a station with vapor recovery pumps. They replaced my entire tank (two) and filler. Haven't filled up yet - hope it fixes the problem. Cheers - Jim
 
What I was trying to say is that it is possible that they both come with 37.5 gallon tanks but the filler neck/vent tube in the 1/2 ton will make the nozzle shut off sooner ( the guy with the 1500 sees that the pump shut off at 27 gallons and assumes the tank is full). Now if they put the filler neck/vent tube from a 1/2 ton in a 3/4 ton you would have problems filling up the last 6.5 gallons of gas. :0:

My theory makes sense because:

1) It is a logical explanation of the problem.

2) It makes economic sense for GM as they only have to stock a single type of gas tank, mounts, skid shields, and fuel tank pickup/pump/sending unit (this is one unit but would have an adjustable float for different size "tanks"). The only difference is some rubber hose.

3) It has been done before - see link below to see what jeep did.

I'm just offering a theory hoping someone will prove me right or wrong :eek:
 
Don't bet hard cash on that theory. There have been a number of posts on the added 6+ tank, I also believe the Sub has the same problem, probably same reason.
 
Why does my dealer insist that he hasn't heard of any "Issues" regarding filling a 2500...in Kalifornia, with the "gators." How can I get proof of the problem and get him to replace the filler neck (it is TINY!) and maybe the tube between the main & supplemental tanks???
Thanks,
JM
 
There is A TSB on the filler neck modification. I had a copy of it let me know if you need it and I'll look for it. I can fax it if you need it. The dealer should be able to get a copy of it. I am in So California and had the mod done two weeks ago. I have only filled the AV once since and it filled fine. I will go on a trip in three weeks and shall see what happens then.
 
Hey Carnac, let us know how the replacement tank went. Maybe we can meet in Aug, I will be driving my AV there for a few days..
