Fixed the fuel spitting problem when refueling my 2010 JKU by replacing the fuel filling tube (Mopar Part #CNNNX321AC)...first fill up after the repair and no fuel spill.
Original part.
Replacement part (bottom of image) with new check valve.
Was that done as a recall? Sounds like it should have been. I don't remember my '11 ever "spitting" fuel, or leaking during fill ups.
No but it really should have been. Apparently service bulletin (#14-003-12) and the associated warranty extension only applies to 2007-2008 JKs. Considering the fact that the same issue affects 2009, 2010, and possibly 2011 JKs I'm not sure why Fiat/Chrysler didn't extend this bulletin to include any other model years exhibiting the same problem...other than to continue the typical money grabbing BS they are so well known for.Was that done as a recall? Sounds like it should have been. I don't remember my '11 ever "spitting" fuel, or leaking during fill ups.
During fill ups I tried changing the angle of the filler, slowing the fuel flow as I neared a full tank, and using different gas pumps all with no luck.My 11 did it for a while, especially in the winter - for myself I've found its more to do with the angle of the nozzle when filling.
So is this stuff almost like POR-15 without actually painting the Jeep, more like spraying a WD-40 on steroids on everything?
Ok so I really like the idea of a protected and shiny undercarriage but the OCD side of me (yes I am diagnosed) is concerned about dust and dirt sticking sticking to the film. What if any experience do you have with that. Please and Thankyou.
Fluid film is great stuff, but it does remain tacky and doesn't wash off easily. If I lived in a place with high salt content in the air or where they salt the roads I 'might' consider using it as an undercoating on suspension parts.
The problem is it makes working around it messy and aggravating. Personally, I prefer to just paint everything with a heavy coat of black Rustoleum spray paint. Easily touched up, gives good protection, and can be removed with a couple swipes of a wire brush if you need to clean the threads off a bolt.
One place I do recommend Fluid Film usage is on electrical components, especially buss bars, battery terminals, and distribution blocks. The FF will seal everything and essentially stop corrosion in its tracks. It can also stop moisture from wicking into wiring, so if you like to try to teach your 4x4 to swim it can go along way in preventing electrical gremlins post dunking. It is non conductive however so DO NOT spray inside distributor cap!!!
I use it on my saltwater boats: liberally spraying it under the cowling of outboards, on hydraulic trim/tilt/steering rams, backside of fuse panels, battery terminals, coat tops of metal underfloor fuel tanks, and on any accessible electrical connection for lights, comms, and switches.
