V70 fuel leak
 

Hi all, I have a leak when filling the car up, I have found the source which appears to be the filler pipe to tank rubber connector. Problem is I cannot see an easy way to remove the old one and put the new one on. I think the best way will be to drop the tank a little to gain access from the inspection hole above. Can anyone give me a few pointers on dropping the tank 50mm? Its a 2001 V70 T5 2WD

I've only seen 3 tanks come down in my life and all 3 were complete removals.

I suggest you drill out the right rear fender liner plastic's pop rivets. They're plastic too and come out real easily.
I did this to track down an EVAP leak so I know it's easy to do.

With the liner removed you be able to see the entire filler neck.
There have been reports of a grounding strap wrapped around the neck such that a hole was worn through the filler neck.

Just have replacement rivets and a pop-rivet gun before you start.

Thanks for the reply. The inner wheel arch lining is already out. I can see the whole filler neck and also the leak, its at the tank end, the rubber sleeve that connects filler neck to tank. Problem is access is so tight I cant get at the clips holding the rubber part on! I was thinking drop the tank a little so I could get at part through the hole under the rear seat but I have no idea whats involved in freeing up the tank?

Not sure what if any difference there would be between your car and a P1 but for what it's worth Haynes say to remove a circlip holding the filler neck to the car then release filler neck and seals from their locations.Supporting the tank the retaining straps are undone and the tank lowered.Whether or not for your purposes you'd need to release the electrics to fuel pump/sender etc before starting the under car operations I don't know but it may be as well to do so.Goes without saying fuel tank needs to be as empty as possible and battery may be better disconnected.HTH.

I had to replace mine a few years ago. Having decided I couldn't be bothered to struggle with it on the drive, I took it to a local garage where I watched 2 guys struggle for an hour and a half on the ramps! Eventually, they supported the sub frame on a transmission jack and dropped the rear end a bit to get access.

Im hoping I only have to drop it 50mm so I shouldnt even have to mess about with the exhaust. Hopfully its not too different from the p1 description.... did you have to replace the pipe or the whole tank?

It was a few years ago, but as I remember, the exhaust dropped down enough once it was off it's rubber mounts.

Like yours, it only leaked when filling up. I think the slackened the front subframe mounts, then dropped the rear bolts right out, but even then, it took the weight of a pretty hefty guy to hanging off it to get clearance. The air was pretty blue by the time they'd finished!

Thats a link to the very one I've purchased :) Will see how I get on trying to replace it! :confused_smile:

Job done! like you chaps say not easy! In the end I dropped the fuel tank 50mm or so to remove the metal straps holding the rubber part to the tank. Once these were free the rear sub frame had to be dropped (front bolts loose and rears removed) to remove the filler neck out of the wheel arch. Just need the Volvo rivets now to put the arch liner back.....

It is possible to do this without dropping the fuel tank or the suspension.

On my XC70 I simply removed the wheel arch liner and removed the filler pipe through the wing after I had taken the locating spring off the rubber gasket under the fuel flap. Reassembled the filler hose and the breather hose with new rubber pipes, fitted the jubilee clips to both before pushing them onto the tank inlets, with a bit of fiddling and swearing, then tightened the clips up. IIRC the pair of pipes from my local Volvo dealer were under £20.00.

Cheers,

Tony
