Thank you. I have an 05 Rubicon, and yes, I meant the GM hose. I‘m not at all interested in band-aid fixes - I read this thread months ago and it sounded like the GM hose was a solution (has a valve that doesn’t get stuck with ethanol use) so I put it on my Amazon Wish List and haven’t really paid much attention to the thread since then. Since I decided to drop the tank this weekend I went ahead and ordered the GM hose.Are you talking about changing the filler hose to the GM filler hose, with the little flapper in it?
Thats what these guys are referring to about fixing the problem, not the symptom. With the GM hose, it will still do the same thing, but hopefully the little metal flapper in the hose will stop it from burping out. I’ve read some posts where the GM hose doesn’t stop it from burping out all the time. If you remove the tank and pull the plunger thing and do what the video says, you will fix it and not need the GM hose.
I may have missed it, but what year is your Jeep?
I don’t meant to kick a dead horse here, just want to understand. My issue is that when I fill up, the pump doesn’t seem to know my tank is full in time and it overflows (unless I slow down to a trickle.) Gas doesn’t come out after I’ve stopped pumping, it never shuts off before full, and gas goes in as fast as the pump can deliver it. My understanding from reading this thread months ago was that there‘s a valve in the tank, and a valve in the filler hose. I thought (from this thread) that a stuck filler valve meant the pump doesn’t shut off in time, and a stuck tank valve meant slow filling and/or fuel spilling after the pump stopped. It seemed to me like there were 2 separate problems being discussed.
Again, I just want to understand so I can learn and fix it properly. How do fuel pumps know when the tank is full? Is there even a valve in the OEM filler hose?
