Problems at the gasstation

Hi there.

As some of you already knows I just got a Patriot 07. When I'm at the gasstation to get fuel the automatic pump stops after i got a gallon or so in the tank and i have to restart fueling. After a gallon or so i have to restart again.

the fuel doesn't get into the tank fast enough, could it be the tank ventilation that's faulty?

Sorry for my bad english, but i think you understand what i ment:eek:

Try pulling the nozzle out a bit and then squeezing the trigger. Sometimes depending on the pump there is too much back pressure causing the nozzle to kick out. I found not jamming the nozzle all the way in works most of the time.
Give it a shot.

I've tried that already, I even held the nozzle about one inch out and could see the fuel not getting into the tank fast enough. It's almost like someone put something down the tube. I was thinking "plugged ventilation" so the air can't escape the tank?

I have tried 4 different stations, all the same for me. It takes about 10 minutes to fill up the tank and I have to restart the whole procedure by entering my creditcard twice since the pump turns itself off due to override in timeduration....

Really, Jeep (or any other manufacturer) would'nt build a car wich can't be refeuled, something isn't working as intended.

Anyone's know how to get to the tank inletpipe and the escaping airtube easely?

the pump cuts off due to issues with the onboard vapor recovery system. If you're in the habit of continuing to fill up after the first time the pump Clicks off, you can cause gas to go into this system. and then you'll have too much vapor at your filler cap causing the pump to shut off too early. You will have to have this piece replaced.

Edit: topping off is bad juju.

Now we're talking. Is there a valve that closes the pipe or so if there are to much vapor? Where is this located? Should'nt it give me an OBD-Code?

I was at the station today, i get about 1/2 gallon in the tank and then the pump shuts off.

I found a yellow electrical box behind the left rear panel today, and som fuses, are they connected to this system?

Is there any way i can check if this system is broken?

The filler vent tube runs parallel with the filler tube and then runs forward.

Have a look underneath to see if it's trapped or crushed. If not you'll have to maybe disconnect the vent end to end to see if it's clear. Just be very careful.

I have some diagrams from the service manual and parts book but can't post them for some reason.

Good luck.

I haven't looked how this is set up on the patriot, but if the car has been topped off, the charcoal canister is basically full of gas, which causes the vapors to come to the gas pump too quickly causing the pump to think your tank is full.

Only way I've seen this fixed personally is to replace that canister. and don't top off your tank! they shut off automatically for a reason. Not aimed at OP, but everybody who tops off! this is typically an avoidable repair, that is not typically easy, and can be expensive.

In this case....I don't care how much it costs. I have 6 months of warranty from the dealer. A swedish law forces him to pay for or repair all broken things found within 6 months if the fault isn't written down in the buyers contract.

I just want to be able to fill my tank without any problems. Going to send the dealer an email tomorrow.

Is this canister in the tank or is it somewhere else?

I have had my Patriot for two weeks now and I have filled it up three times. One owner before me and it has 40.000 km on the road. It saw Swedish daylight in August/September -08. I guess I can see the fillertube via left rear wheelhouse? I'm so thankful for all input here, i have 200 km one way trip to the dealership and therefore would like to find and fix the problem myself. Depending on the weather tomorrow (it's snowing now) I'll have a look under the car, I don't have a garage or a worshop to do the repairs in.

(Does this forum run in Tapatalk?)

What works for me is to rock the car sideways--causes the gas to "settle" and then another 1/2 to 1 gallon can be added. And, if I'm on the road, I'll fill as much as possible, otherwise need to allow some expansion room for parking in the garage.

Fuel Filling Problem

Patrick,

I just bought an 09 Jeep Patriot and have the same problem. I took the gamble and paid $200 to have the fuel filler neck replaced yesterday (2/9/13) by my regular mechanic. It did not solve the problem. On my way home I stopped by a Jeep Dealer. The Service Manager said it could be a flapper valve inside the tank itself is sticking. He told me to try bouncing the vehicle by pushing down on the back bumper next time I try to fill as this sometimes will cause the gas to splash and loosen the valve.

If this valve is bad the entire tank needs to be replaced as it is molded around this component.

I'm probably gonna live with the problem for a while as I'm still reeling from my poor gamble.

Let us know if you get this fixed!

Thanks

Thanks alot, this kind of information is great for me. The repair manual says there are one or two valves in the tank, depending on model.

I found a yellow electrical box behind the left rear side panel and 3 or 4 fuses, what does this box and fuses do? Are they related to the tank?

Been thinking a bit....Do you think it's possible to ram something (a cable) down the pipe and open the vent? I don't mean to use exessive force while doing this, just to push it open if it's stuck in closed position...

Heres some information below. Looks like it is part of the towing package?


http://www.ecs-electronicsuk.co.uk/towbar-wiring/spares

ECS CAN-bus technology
The Can-bus technology can be compared with a fast computer network. This is ideal for communication between two pieces of electronic equipment. By using this Can-bus technology less wires and connectors have to be used to install a wiring kit into a vehicle. Where possible, ECS uses this technology to replace bundles of wires. This technology is perfect for wiring kits for towing equipment.

Ok. That's why I can't find it in the service manual. I had the seller to install a towhook before i bought the car.

Does anyone know if the valve in the tank is mechanical or electrical operated? I wish i had a probe to look inside the tank...

After living with this situation on my 2010 for 6 months and through an Alaskan winter I finally went to my mechanic and had him look at it. After 3 visits and some searching, they found out it was a tank issue. He said that numerous jeeps have had this problem. The tank valves are not venting properly and the entire tank needs to be replaced. But because it is a TANK is the problem, it could happen again even with a new tank. 😞
And it's now 2020 and these parts are going to be discontinued. Only aftermarket parts or used will be available.

Another option to consider:

Actually a manufacturer is required to have on hand a 7 year supply of spare parts after the discontinuation of a product. I work as a tech support rep for a radio company and I constantly have to explain to some guy who has a 30-40 year old radio (and yes I do get these calls often) that we don't carry spares for their radio anymore.

Another thing you can try is thumping on the side/bottom of the gas tank (made of plastic) where the rollover valve is with your hand or a rubber deadblow mallet and see if the valve shakes loose. No guarantee it will work, but doesn't cost anything to try it.
