Fuel Tank Venting Hose

[scbond 15 1 Cars]

Tried searching and studying the ServiceBox diagrams to find an answer for this but couldn't find anything. Basically, I found that the tank venting hose that runs from the white plastic valve on the filler neck runs down and through a hole in the wheel arch and then has nothing on the end and figured that this may have something to do with the strong smell of petrol while driving.

 

 

 

The car is a phase 1.5 ('89) 1.9 GTI...is this vent as it should be or is something missing from the end?

That is how they are.

Mine has some sort of valve on the end and I believe is original to the car (88 1.9).

That looks like the sunroof drain pipe that goes down to the rear of the car.

It comes from the non-return valve on the filler pipe...and mine is a non-sunroof with dealer fit one.

Thought this may be the case. Could this be the reason my car stinks of petrol while driving and often while idle? No leaks to be seen so could the valve at the top of the pipe be stuck open or something?

I have seen that there's a valve but not for the phase 1/1.5...there's definitely one on the phase 2 which then goes to the engine bay. On ServiceBox it also looks like there's a valve on the end of the pipe but that's listed for the regular saloon.

Yours a phase 1.5? Do you know what the part number is for the white plastic valve?

[dobboy 231 2 Cars]

Yeah Ph1.5, sorry i don't. Tried that "miami stu's" website?

 

Btw, i think it clips somewhere around the sort of towing eye thing behind rear valance......i cable tied mine on as i couldn't work out exactly where it should go.

Been using ServiceBox...Stu's site is basically an old version of this.

 

Big ask but could you possibly get a photo of it?

[dobboy 231 2 Cars]

Yeah sure..... Will do tomorrow.

hope this helps, the white one way valve is located in the top of the wheel arch with the filler pipes.

Cheers Paul. Think I recall seeing this pic while searching. Was there anything on the end of your black hose? And is it easy to remove the valve to clean/check operation (I think you said you can test by blowing one way but not the other)?

The valve is No longer supplied

 

I do keep them if you want a new one.

 

Got to be plenty of used about also.

Nothing on the end of the hose (at least not on mine) and the valve is a one way device so easy to test by blowing through it. Access is a real pig as the clear pipe runs behind the filler pipes and the fixing holding the pipes in place is usually corroded solid, but if you can get enough play around the valve you may be able to remove it.

 

Perhaps the best way would be to suck/blow down the black hose with everything left in place.

[scbond 15 1 Cars]

Ok, will give it a test...should be able to suck but not blow?

 

If the valve is fine does anyone have suggestions for what the heavy fuel smell could be?
