Leak when re-fuelling - filler pipe connector?
 

Hi guys

XC90 T6 2.9 2004

Had a strong whiff of petrol after refuelling recently - but goes away more or less by the time I get home. An obvious culprit ( according to the internet! ) is the top of the pump, so I spent a while exposing that the other weekend and it was completely dry. It has been a bit random, I don't do many miles so am not refuelling often, but it does always do it, didn't seem to matter if filling to full or not.


Yesterday I noticed a lot of dripping whilst re-fuelling so drove round the corner and got straight under the car - looks to be the rubber connector between the filler pipe and the fuel tank, which is only a £12 part. That connector was totally soaked. However, I cannot feel any obvious splits in it - but wondered if anyone had any experience getting this replaced? It sounds to me like yet another sub-£20 part that will cost me £200 to replace in labour! ( e.g. ABS Sensor rings )

I also wonder if perhaps the breather pipe not clear, causing the fuel to sit up in the filler pipe for longer than perhaps it normally would do - I really don't know how much fuel 'sits' in the filler pipe and for how long when you fill the tank, but in this case I was only filling to around 2/3rd full..

As I say, it is only exhibiting this as I am actually putting fuel in - and I could see no sign of fuel above the level of the connector so I don't think there is a hole in the filler pipe itself or the connection to the fuel filler cap area.

Many thanks!

Well it certainly sounds like you have found the problem.

Could the rubber pipe/connector have gone porous?

If you don't want to pay someone to fit a new one for you, then you may just need to live with it for a while longer.

As you say it only happens when refilling, and you don't fill up that often so not a major problem really.

I have a similar, but different, issue with my bike in that if I fill up 100% I get a weep of petrol from the seal around the top plate on the tank.

Now I only ever put 10 litres in at the 100 mile point on the trip and it's happy days.

Edit - Have a look at this ebay listing from Caffyns - they say it's a common cause of fuel leaks

Thanks Dave

I have asked my local garage to replace the pipe - they said it would take approx 1 hour ( but a bit of a guesstimate I think ) - worse outcome is that they find something else and I have wasted £15 on a connector I didn't need - either way at least I will find out what the problem is I guess! I will ask them for the old connector to see what the exact problem was. I'd rather get it sorted - it was less of a weep, more of a sob.....

Thanks for the update

Good luck with the garage, let us know how it turns out.

Leak fixed, there was a split in it, but couldn't feel it as it followed the ridge in the rubber. Charged me an hour's labour - they had to remove the spare to gain access - bet they had fun with that, I suspect it it was the first time in nearly 15 years! I will try to upload a pic at some point as I have the removed part

Glad you got it fixed

Cheers

My fuel pipe connector is leaking. Anyone know where I can get one? Struggling at moment to locate anywhere. Especially in the K shape, can I put a normal 4 way connector on them?
