Benjamin2112 Posted November 1, 2017 Report Share Posted November 1, 2017 Hello everyone, I'm having trouble with my capless gas, not sure if i will need to replace it or not. My edge keeps throwing codes for emissions and I have narrowed it down to the capless gas area, it will sometimes be hard to insert anything into the hole and this is usually when it begins to throw codes, are there any ideas on whether i can repair the existing part or do I just need to replace it, any inquiries are greatly appreciated.

akirby Posted November 1, 2017 Report Share Posted November 1, 2017 I think you have to replace the filler neck. Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted November 1, 2017 Report Share Posted November 1, 2017 The filler neck and the purge valve are the two most common issues I have seen on the 2011-14 MYs. Quote Link to comment Share on other sites More sharing options...
IWRBB Posted November 3, 2017 Report Share Posted November 3, 2017 Just had our 2010 Fusion pop a P0456 code the other day. Internet says filler neck or purge valve. I cleared it and it hasn't come back yet. I use a locking "cap" on the capless filler of my F150 to keep out dirt and dust- maybe I should do the dame to keep crud out of the filler on the Fusion too. 1 Quote Link to comment Share on other sites More sharing options...
chefduane Posted November 3, 2017 Report Share Posted November 3, 2017 If the filler neck isn't sealing properly that may throw a code. I also have a locking cap on the capless filler. I'm an old school guy - I gotta' have a locking gas cap. Just feels weird not to have one. 1 Quote Link to comment Share on other sites More sharing options...
IWRBB Posted November 7, 2017 Report Share Posted November 7, 2017 (edited) I don't care if it locks or not- I just want a cap to keep dirt out of the fuel filler. It's begging for dirt and dust to collect in there with the way it's designed. I wish it just had an old school setup with a normal cap really. Our '10 Edge has a normal cap, and I'm glad it does.

omar302 Posted November 7, 2017 Report Share Posted November 7, 2017 I don't see why dust or dirt would collect at the filler neck. I live in a dusty area and the filler area behind the fuel door is always clean. There is a gasket on the back of the fuel door that is supposed to seal the filler neck when the door is closed. Maybe the fuel door is not closing properly. Quote Link to comment Share on other sites More sharing options...
akirby Posted November 7, 2017 Report Share Posted November 7, 2017 That's what I was thinking. I've never seen any dirt in any of my vehicles. Quote Link to comment Share on other sites More sharing options...
IWRBB Posted November 7, 2017 Report Share Posted November 7, 2017 My point is the capless filler using a design that has a large open/recessed area that leads to the fuel tank seems to be, not the best? The gas door seal may work for now, but if the seal is damaged, then what? New filler neck and fuel door? . Could it not have had a flapper at the top of the "hole" as a deterrent to debris and dust? The whole setup just seems like a solution to a problem that never existed, which in turn fails and actually creates problems that never existed. A $6 gas cap is a lot easier to replace than a filler neck. I guess I'm just a luddite. 1 Quote Link to comment Share on other sites More sharing options...
chefduane Posted November 7, 2017 Report Share Posted November 7, 2017 (edited) A gas cap (locking or not) would keep most, but not all, dust and debris out of the filler neck. A locking cap accomplishes that and locks also. The cap I have completely covers the filler neck and tube flap. Best of both worlds. Plus I have the sense of well being that some young whippersnapper won't pee or put sugar in my tank, gollygarshdadgummit!

akirby Posted November 7, 2017 Report Share Posted November 7, 2017 It already has a cover to keep out dust and debris - it's called the filler door. If you're getting dirt and debris in there then maybe your gasket isn't working. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted November 7, 2017 Report Share Posted November 7, 2017 The fact is dirt does collect at the fuel filler neck, at/behind the flap, that is where the concern is. And thats why FordTechMakuloco has a video on how to clean it. Quote Link to comment Share on other sites More sharing options...
