Fuel Overflow Onto Garage Floor

[MartinWindsurf]

Mine's a yr2000 1.9TDi Mk1  - in the last year whenever I fill up, if I leave the fuel filling till it clicks off, it dumps half a pint or so of diesel on the filling station floor behind the drivers seat - some sort of overflow pipe.

 

Am guessing it is a stuck one-way overflow valve or similar.

 

Anyone had this problem and fixed it?  Tips/instructions welcome.  Didn't fail the MOT on this.

 

( solution so far: I never try to fill to within 5L of completely full! )

Not had the problem, but would sound to me like the return line or one of the rollover valve bits on the top of the tank has come off its housing or connector. Or maybe the return line has a hole in it?

 

It should be fairly easy to find the source of the leak with someone to help you (they fill the tank while you locate where its coming from).

 

 

Is it anywhere near the booster heater area?

 sounds like your breather valve is sticking?no such thing as an overflow valve! the only think stopping you overfilling your tank is the click off valve in the filler nozzle and the price of fuel other wise you would pump  fuel all over the forcourt!

if it was the return pipe it would pee out constantly when you fired up the engine!

you could pull the inspection plate in the floor and take a look at the hoses and check for leaks?
