I have a 2014 titan S, that I bought brand new last year it now has 22k. Here is the issue "sometimes" while filling the tank gas will back flow out and down the side of the truck.

-It only seems to happen when its colder out

-When the tank is on E

-Will not back flow after I fill the first 1/4 tank

-It will do it if I stop pumping or it will cut off like the tank is full and back flow then too.

-Seems to do it for multiple fill ups in a row and then stops for a little while.

Has anyone else had this issue, and did you ever find the fix for it. The dealership is baffled and they can't just warranty parts and hope to fix the problem with one of them.

I found a few other titan owners that have had the same issue but have not found a fix to the problem.

There was a recall for something like this on 04 early 05. Might be the same. Try a search and look at some of the old threads.

Thank you! I had it at the dealership yesterday for the second time. The techs
biggest like WTF is the fact the pump shuts off THEN it back flows it doesn't do it while the pump is running.

Which means it's not letting the gas in the filler neck finishing flowing into the tank after the pump has stopped.

I just wanted to see if I could give him some direction with what part exactly to replace.

My 05 XE NEVER did this. I don't think filling it slower or not letting it get to E is a solution for a truck that's under warranty.

I want Nissan to fix the problem one way or another! I love my titan it's not going anywhere but this problem needs to be fixed.

Thanks guys!

I had the same issue with mine when it was really low on fuel. Something is causing an air pocket.
What year was yours? I posted it on instagram and a guy with a 2015 said it happened to him that day. It seems to be hit or miss what titans have the issue. Like its a bad design of a part mixed with bad product control when making them.

My 04 has done this forever. Try filling your truck slower and keep at least a quarter tank of fuel in your truck. I forget exactly what the part is called ,evap vent control valve I think. It's a box located next to the gas tank and filler tube.Here is a write up on it but the pics are missing.http://www.titantalk.com/forums/tit...m60b-evap-vent-control-valve-assy-sticky.html
I know that seems to prevent it, I just don't want to use that as a solution for the next 10 years. I will thank you!!

My '08 does the same thing, but usually only once every now and then (months apart). Once I slowly get it to about 3-4 gallons I can let it go and it fills up the rest of the way. Only time it ever bothered me was when I used 30 cents off at Kroger and walked into the store to buy a drink or something and it shut off after 1 gallon long enough for the pump to reset.

Mine is a 2012. I agree, it only happens if down at E, seems fine if at a .25 tank or more.

Yeah which only seemed to baffle the tech even more. Mine seems to be related to colder weather, it started this time last year stopped for months as soon as it went from 75 to 50s started again.

Have you ever had it looked at?
No not yet. At first I thought it was just the gas station I was using.

I did as well I first discovered the problem because I started pumping and needed to fix my glove so I let go to stop pumping pump stopped it back flowed. Then it followed with cutting off on its own and back flowing.

I talked to someone who has a 2015 that just did it, he thought it was the way he put the nozzle in. I'm like unfortunately no its not that, get it checked out.

Mine seems to do it in waves, I actually thought it was a valve that finally worked it's kink out and stopped sticking. Then after 6 months it started back up. I'm a 1/4 tank right now. I'm going to run it until E and see what it does this round.

If you want to check out the video I posted it's on my instagram sjw_87.

It's good practice to keep at least a quarter tank of gas in your truck for several reasons. One being your fuel pump will last longer because the gas in the tank is what keeps the pump cool especially in the summer.

I always run it to E in the summer, it doesn't have the back flow issue until the weather gets cold. When I don't usually let the tank get below 1/8-1/4. Even the nissan tech said he runs his to E also.

That's good to know though, thank you.

I had this problem last year on my other truck (Xterra). Replaced the evap canister and solved the problem. PITA pumping gas for 10 seconds then letting off, pumping gas then letting off, over and over until I had enough gas to get to work. I found info on my old forum how to purge the blockage, etc, but nothing worked. I just shelled out the money for the new part and all was well. I think it cost me $150, installed. Worth it, with a Maine winter about to hit. Pumping gas here SUCKS when it's 12 degrees and 35 mph wind freezing your hands off lol Didn't hurt to stare at my mechanic AGAIN for another hour
