Gas leaking when tank is filled completely. Help please.

[mazzidumato]

I filled the tank after replacing the fuel lines and all of a sudden had a lot of dripping in the center of the van. Upon inspection and lowering the gas tank (picture 1) is what I noticed is broken. Does anyone know the name of these? According to the mechanic here i Mexico, these are for the gas fumes to leave and shouldn't leak unless the tank is over filled. Maybe replacing this broken part might resolve. Any suggestions? And if there are parts similar that I would find in Mexico?

That's the cross over.
They always break.
Reseal your tank, since you have it out now.
Buy the kit and these fittings will be included.

Plastic and rubber on these vans, especially with the fuel system gets brittle and fails over time.

You can go with new plastic fittings like the one in the previous comment. I know I've seen some folks fit metal fittings for those hoses too.

If that failed, check and see if you still have the plastic fuel connector on the firewall (passenger side) that connects the fuel hose from the fuel filter to the fuel supply hose coming in to the engine system. If you still have that item have it removed and replaced with a metal unit.

Since we are in Mexico and couldn't find the specific parts. This is what the mechanic thought of. Any reason this could be a problem?

Thanks skemems. This is pretty tight. 👍👍

This may have been covered in great detail a time or two before, this is a great time to learn to use the FAQ’s they are quite handy and cover 99% of what happens to our vans.

You don't want any undue force between the fitting and the grommet, as that may cause a leak. What you have shown may well work, but I would try to find molded hoses to fit onto the vertical fitting to take some of the twist out of how the hoses fit. Maybe use what the mechanic has made up for now and order the correct parts. My experience is that some kits are way better than others, but its been quite a few years at this point since I bought a kit, so don't want to comment on any specific one.

I have a similar issue when I fill up the tank and after driving awhile the issue is resolved. Anyone know what the cost might be to have a VW repair shop fix the issue?

^^^ $100 an hour is dirt cheap anywhere where people live. Don't be surprised if any shop willing to accept this job charges $185/hour.

If you still have the original tank, and pay for this work, personally there’s no way I’d pay for the labor and NOT replace the fuel tank.

There’s still plenty of $100/hr shops in America around in less-expensive areas of the country. I’d suspect Panama is half of that.

I just had this done at a Tucson shop -- I provided the kit and they did the work: $500.

I'm past an age where I enjoy lying on my back under cars and I no longer have my lift so I was happy to pay. Everything was perfect the first time (which isn't always the case with this project).

Filled the tank to the absolute max: no runs, no drips, no errors.

Looking at the bill, they charged me for 3½ hours @ $140/hour plus $10 in shop supplies. This is a shop that specializes in Mercedes, Porsches, BMW and Vanagons.

I brought the van in with the tank almost empty and a 1 gallon can of gas on board.

I just did this job on my van last Thursday. 6 hours for me including draining 1/2 tank of gas. I already did a reseal a couple years back, the reason this time was a tank swap for the 12mm outlet, and later fuel filter, getting rid of that plastic cube.
My clamps were all "new" fuel injection clamps so undoing was a breeze.

I reused all my seals as they were mint from having just been done a couple years earlier, so no surprises. The evap lines are the biggest pain in the butt to fish through. The tank I took out is extremely clean, my vehicle has not seen winters, so if you are doing a reseal, I would not automatically change the gas tank, unless it looks crusty. I really prefer OEM VW parts as opposed to some of the trash being offered today.
That being said the Spectra tank I bought looks well made and fit perfectly.
