The filler neck can be replaced - and may even be subject of a recall. After the first coat sets repeat the process to apply a second coating of fiberglass solution.
Otherwise no gas smells when driving no leaks after filling.
Gas tank filler neck leak. Drain the tanks gas until it is past the area where it leaks. Then with sandpaper this might be included in the kit sand down the area around the crack. Now mix the provided fiberglass mix and apply it to the crack.
After the first coat sets repeat the process to apply a second coating of fiberglass solution. This is the big rubber flex hose that leads from the filler neck to the filler pipe lower assembly that bolts to the fuel tank. It is clamped at the filler neck and at the lower assembly.
This is the part number fer the fuel return hose small rubber line when you max out the fuel in yer fuel tank. Might have a leak in the fuel filler neck. Either the neck itself has a hole rust or the short rubber hose that connects the neck to the fuel tank is bad.
Normally the fuel system is sealed if the gas cap is loose for example that will cause a check engine light. I think you have a hole somewhere in the tank or filler neck that is causing this. But a hole in the filler tube would leak liquid only if the tank is overfilled up into the tube which shouldnt be done because it can cause liquid fuel to get into the charcoal vapor recovery box also up behind the right rear wheel.
A flooded recovery system could give off fumes leak gas and cause a. About 2 litres on the floor for every 10 litres in the tank. Otherwise no gas smells when driving no leaks after filling.
I pulled the seats out and checked the fuel pump which is fine with no leak. Then I checked under the car while adding petrol slowly and the leak is above the fuel tank somewhere between the filler neck and the main tank. Part of the new install was a new Spectra gas tank.
It has a very slight leak at the the tanks filler neck. It actually seeps from behing the end of the hose where it seats up against the tank. It only does this with over a 12 tank of gas.
That point is exactly where the tank outlet meets the filler neck. Gas smell is mostly at the rear or just beside the gas cap area. Jacked up the van today and saw the leak right away.
It seems to be coming from the lip of the hose coming from the filler neck connecting to the tank itself. At first I thought it was the fuel pump housing crack like. If it happens during refueling the filler neck may have rusted allowing some fuel passing thru it en route to the tank to leak out.
The filler neck can be replaced - and may even be subject of a recall. Contact you dealer to make sure it hasnt been recalled for these types of problems before spending your money to fix a manufacturers defect. On Sunday I was off-roading and someone noticed fuel leaking from my vehicle.
Upon inspection we saw fuel dripping from the filler neck vent tube assmebly where theres a bracket welded just above the rear cross member over the rear axle. It appears that it may have cracked from the shock etc of off-raoding. The fuel tank filler neck can crack and separate allowing fuel or fuel vapors to leak from the fuel tank.
This poses a fire hazard to consumers. The firm has received 1048 reports of the filler neck cracking or leaking. Of course youll need to drop your tank and then remove the filler neck to do that.
Ive also seen a truck where the tank had pinholes right below the bolted-on plate. If you look closely you will see that the plate isnt flush with the tank its a little bit raised. It had tiny holes right there where it.
If the filler neck hose is leaking you may want to consider replacing all the soft fuel and vent line hoses even those on top of the tank to prevent more problems with leaks. 20 plus year old hoses cant be very good condition I know mine werent. Discussion Starter 1 Jun 23 2017.
I uncovered the annoying leak in the hard-to-reach fuel vent line from the fuel tank to the filler neck last night. I was originally thinking it was the seal on the fuel level sending unit so I replaced that and took it to the gas station to fill it up and check that everything was ship-shape. The filler neck is fitted on the passenger side at the top of one of the tall sides of the fuel tank.
In order for fuel to fill up evenly on both sides of the fuel tank depressed area VW came up with a somewhat elaborate way of venting the fuel vapor. The system is comprised of a transfer tube assembly three grommets and about a meter or so of 5mm fuel hose. There is also a grommet around where the filler.
I noticed today when i was filling up my gas tank that there was a pretty significant drip coming from what i assumed was the filler neck. Because once i stopped pumping gas the drip stopped. And i was in my work clothes so i didnt want to get underneath and look at it.
Im gonna go out on a limp and assume the filler neck is leaking. I know the right thing to do is to drain the tank drop it wash out the tank with water let it sit in the sun to dry etc and then have it welded again. I read some previous posts that mentioned putting JB weld around the filler neck to stop the leak which I did.
I have been getting the P0456 code for small EVAP leak for about two years. I have paid to have several smoke tests they found no leaks and replaced every component in the EVAP system at least once except for one – the fuel filler neck running from the fuel inlet to the gas tank. I am guessing it has a small leak or two somewhere in the tube.
Turned the key on the ignition to engage the fuel pump. Immediately when I did this fuel starting leaking out of one of the line connectors that plugs into the fuel pump. I then started the truck up and fuel continued to pump out of that leaky connector as expected.
