Our 4200 spyder looks like there is a leak from the fuel filler pipe. It is not clear how to access the pipe. Does anyone know the correct procedure please

there are no rear seats and having taken the rear lining out, it shows no access at all.

Hi, what has lead you to conclude there is a leak in the fuel filler pipe?
Smell of petrol vapour in the cabin after filling perhaps?

Ah, when you put it that way. First thought is to very much err on the side of caution and trailer the car to your preferred indi. specialist.

I asked about vapour as the fuel pumps are known to develop cracks. Access to the top of these is fairly straight forward from the roof compartment. Whereas, getting to the filler pipe / tank union is more complicated. I believe the roof pump needs moving - although I can't find anything definitive. If you've a endoscope you might be able to see where the leak is coming from.

We have tried the endoscope route without success. It might be a pin hole in the feed pipe.

Different car but I had a leak on my Golf a few years ago and it was the seal around the level sensor.

It was fine normally but if you brimmed it it would pour out due to the extra weight against the seal.

I had this last year on my Spyder. Turned out to be a small rubber seal on the fill/vent line. (looks like a little green top hat) You don't have to remove the roof pump. it's awkward but you can get to the filler pipe by removing the panels in the hood well. I replaced the fuel pumps whilst I was at it because they also have a habit of developing cracks in their screw tops, and I think they were only about 500 pounds for the pair of them.

Thank you. How did you work out it was the green seal ?

Well, to be honest it was a real chore. We suspected the little seals and the corrugated plastic pipe from the get-go, so we replaced both, but that didn't cure it first time.

The seals are very delicate and one had been damaged on fitting, so I still had the leak! We ended up doing all sorts of stuff before we finally went back to look at the seals again. I eventually found it by taking the car for a bit of a drive round some bends and then stopping and shoving my hand up into the area where the filler pipe is inside the rear wing... that's when I felt the leak dripping.
The fix took all of 30 minutes!
