DubbsFaris Posted March 3, 2011 Report Share Posted March 3, 2011 So as soon as I got back from the bash, I noticed my gas tank would shut the pump off like it was full everytime I tried to fill it. It would take me 20 minutes+ to get my tank most of the way full and it was also throwing a couple codes at me. P0456 and P0442 (I think) So Jordan Ford has had my car for coming up on three weeks. Ford had them replace my fuel pump first, then the whole fuel tank. No luck. Then, today, Ford happened to have a couple of their mustang engineers down at the dealership on an unrelated visit, but showed them the car and asked for their help. Well, they found it- it seems the exhaust got so hot on the track it melted the vent tube, so it will now be replaced and they told me the heatshielding was not enough to keep this from happening. Now if you are only doing regular street driving, this will never happen, but under track use, your exhaust gets really hot! For more questions on this, please contact SA, as they are aware of what happened, and will make sure this issue doesnt happen again. This may be an isolated incident, but I thought I would share what happened just in case it does come up. Its no big deal, once we found the real culprit, and Ford is covering it under warranty in my case, so be aware of the symptoms and cause. Link to comment Share on other sites More sharing options...

07SGT5687 Posted March 3, 2011 Report Share Posted March 3, 2011 This is very interesting... My old 05 GT did this HORRIBLY! It SO pissed me off. All the sudden one day it would not fill without me clicking the damn handle 100 times in a row. Had to fill it really slowly at about 1/4 pump speed. I wonder if that's what happened to mine. Drove it a lot on hot days and cruises/track events. Very interesting... and kinda scary. Link to comment Share on other sites More sharing options...
DubbsFaris Posted March 3, 2011 Author Report Share Posted March 3, 2011 Yeah, it is a Ford issue, but I know Shelby is looking to see what more they can do. I was surprised that when I got the call, I didnt hear- "well, Shelby changed the exhaust so it is their problem", but in fact what I got was, "even though the exhaust is from Shelby, the location of it is the same as a stock exhaust, so we will get you a new vent tube and get it fixed!"

Doug_GT350 Posted March 3, 2011 Report Share Posted March 3, 2011 I have heard about this on GT500 where the exhaust was changed with larger diameter tubes..... but the strangest thing is that I just had the same fueling issue on my SGT! It has never been raced and has 6k on the clock! I was thinking of crawling under it this weekend to take a peek.... now I know I WILL!!!

DubbsFaris Posted March 3, 2011 Author Report Share Posted March 3, 2011 Jordan Ford in San Antonio. I hear they sell more mustangs than any dealer in the country, but I have nothing to back that statement up. They treat Shelby owners VERY nice!

shel-b001 Posted March 4, 2011 Report Share Posted March 4, 2011 Could we be onto something? Anyone have pictures showing the location of the vent tube? I take it they are just a plastic tube runnong up to the gas cap neck. Link to comment Share on other sites More sharing options...
Troy Reed Posted March 4, 2011 Report Share Posted March 4, 2011 Had this issue on my 06 GT. I read about a fix for it, but it didn't happen enough for me to take any action on. When it did happen though it was frustrating. Link to comment Share on other sites More sharing options...

kahmann Posted March 4, 2011 Report Share Posted March 4, 2011 The issue with 05-07's was corrected in 08. The cause in the older cars was the filler neck itself. It's completely unrelated to the vent tube issue in the 11's. Link to comment Share on other sites More sharing options...

tony356 Posted March 4, 2011 Report Share Posted March 4, 2011 Warren Thank you for all your insight with our cars and for being the real world test mule for all of us. I will have my dealer look at the issue before the pocono event. If you hear about SA's resolution to preventthe problem, please let us know.

It's completely unrelated to the vent tube issue in the 11's. Thanks. I was kinda worried about that after I read this thread a couple days ago. Good to know it's safe... but it's still annoying as hell. Wonder if there is a retrofit (or update... upgrade?) for them? Link to comment Share on other sites More sharing options...
kahmann Posted March 4, 2011 Report Share Posted March 4, 2011 What was the issue with the filler neck. I not sure but was there something with the tank being a saddle tank & air was getting trapped ? No it was actually just that the filler neck hose was too small and narrow. The 08's came with a wider hose, that's it. However, in 2010 (I believe), they ran the evap tube up into the side of the filler neck hose, to further help with venting. I've intended on modifying my filler neck so that it was plumbed the same way as the new cars, ever since I found the change on Ford's drawings. I need to get rid of that 20+ lb. mess of evap crap under the wheel well first though! Link to comment Share on other sites More sharing options...

kahmann Posted March 12, 2011 Report Share Posted March 12, 2011 Whats THAT all about? It's EPA crap. "The EPA requires EVAP systems on cars because gasoline fuel vapors contain a variety of different hydrocarbons (HC). The lighter elements in gasoline evaporate easily, especially in warm weather. These include aldehydes, aromatics, olefins, and higher paraffins. These substances react with air and sunlight (called a photochemical reaction) to form smog. Aldehydes areoften called instant smog because they can form smog without undergoing photochemical changes. The bad thing about fuel vapors is that fuel evaporates any time there is fuel in the tank. That means if the fuel system is unsealed or open to the atmosphere, it can pollute 24 hours a day even if the vehicle is not being driven. Uncontrolled evaporative emissions like this can account for as much as 20 percent of the pollution produced by a motor vehicle. The EVAP system totally eliminates fuel vapors as a source of air pollution by sealing off the fuel system from the atmosphere. Vent lines from the fuel tank and carburetor bowl route vapors to the EVAP storage canister, where they are trapped and stored until the engine is started. When the engine is warm and the vehicle is going down the road, the PCM then opens a purge valve allowing the vapors to be siphoned from the storage canister into the intake manifold. The fuel vapors are hen burned in the engine. Evaporative emission controls were first required on cars sold in California in 1970. EVAP has been used on all cars and light trucks since the early 1970s." http://www.aa1car.com/library/evap_system.htm Link to comment Share on other sites More sharing options...
