Gasoline tank thump

[Liptoss]

I can hear you knocking, but you can't come in.

OK, so I've an appointment with the dealership next Tuesday for AGAIN the driver door ajar warning sensor/switch. They fixed it once and it's back again. Drives me nuts... it can't be ignored! It'll ding-ding with every slow/stop that I come to.

With the factory 60 k almost up in 10 days I'm having this done AND I'm going to have them look over the filler breather/vent tube for the petrol fill. Thunk-thunk after a fill up.

I tried last fill up and notice I could fill a heck of a lot additional fuel and it never over flowed. I also notice that the fuel gauge registered higher on the console display. Usually I've been not pushing the "extra" petrol into the tank after the first click stop of the pump at the station.

So, I'm wondering is there anyone out there that has had their Edge looked at for this issue?

What exactly was found and the resolve that was implemented?

Or

Is this even an issue?

Vehicle runs fine and fuel consumption inline with others at about ~9.5L per 100km's or 29~30 mpg highway and 12~13L or ~22 mpg in town.

Is this something that I could look at for the vent /breather tube? I'm handy and not scared to take things on myself. I simply need to know where I might start looking for "this potential" problem with EVAP?

I recall years ago being told by my mechanic buddy that when filling fuel, "Don't pump and pump to round up the cash value to even it as you risk overflow of raw fuel back to the EVAP canister with the charcoal and that can damage it and it is a costly part to replace."

Any thoughts anyone?

Thanks

The issue may very well be your capless filler neck valve. I would recommend cleaning it best you can and then getting some WD40 and a small plastic hose or funnel and then plunging it repeatedly into the filler then spraying it and plunging it again then wiping it out. This has been done with others tanks on Youtube and had good results. Also clean the gasket real good around the cover of the tank lid. Inspect it to ensure it has a strong spring and closes completely. This helps keep road garbage from entering the filler neck.

Hey Liptoss,

 

I'm glad to see that you've scheduled an appointment with your dealer, as they're in the best position to assist with a diagnosis and next steps for both concerns. What's the current odometer reading on your Edge? Please let me know and I'll see how to help on my end.

It's currently in for a few items, one being replacement of the filler neck.

I've clocked many k's the last couple of weeks and filling the tank has become hugely unpredictable. I've not wantied to overfill and dump raw fuel into the charcoal can (an expensive proposition). Pretty much any pump I've used doesn't seem to fill the tank, leaving the fuel gauge always reading less than full. Still hear the thump-thump sloshing sound from back under the rear seats too.

Pick up the vehicle later, I'll post what I observe over the next few days for improvements.

Thanks to all for input.

Well while it was in for door ajar latch/switches, they replaced the filler neck. It looks like some sort of new slightly concave flapper now all shiny and new.

Anyhow, I've been through a number of fill ups now, and it still seems to behave the same way. The tank once never filled up completely according to the on dash digital gauge. Usually it is immediately filled at the Full line, but after a few kilometres moves below full. Guess I'll have to live with this idiosyncrasy (or normal behaviour). The "free" warranty is up and I don't believe this is covered under the extended. But I believe "other" emissions components that may be affected with time would be...

But that's another EDGE story.

Wouldn't worry about it unless it is very easy to hear under any condition. Most likely culprits are improperly attached fuel tank straps or loose/missing baffles internal to the tank. They should have checked the straps at the dealer though.

[Liptoss]

Loose tank straps? Is this a systemic issue as well with this vehicle?

[WWWPerfA_ZN0W]

Not at all, just a possibility derived from across the vehicle spectrum.
