Emissions pipes 1993 -identification of small pipe.

[Bremar 2]

Hi, 

I have a 1993 Gentry. During the process of  wax oiling under the offside resr wheelarch I saw part of the emissions control pipework. Ive attached link to YouTube vid 

i have found the schematics in my Haines  workshop manual and on line. Neither seem to show 2 pipes going to the fuel filler pipe. 
and I appear to have 2 pipes from the filler neck as well as the actual fuel filler pipe? 

The clear plastic unit at the top maybe the safety valve? But where does the other end of the pipe go, I can’t see it going to the fuel tank anywhere? And it doesn't look as if it goes to the fuel pump or sender unit.  
 

 

 

any advise or information would be appreciated. 
thank you.  

Bremar.

It's all on the drawing but the Haines workshop manual is a bit generic here, just look at the engine orientation.

 

Here is something closer:

Nothing to do with emissions on UK cars. It is just the breathers from the fuel tank. On top of the tank there is a small bore maybe 8mm connection and a larger one at circa 20mm. Which are the connections you see on the filler neck.

I think a gentry would have an evaporative emissions system on their low compression cat equipped 105 bhp 1.9, same as the 1.9 cti.

 

Check for the charcoal canister in the left wheel arch ahead of the wheel, you'll see some plastic tubing running along the floor next to the fuel/brake lines also.

Thanks for the guidance and I've attached some photos. One shows the top of  a 1.9 Gti fuel tank and I can see that it has provision for 2 connections for the thin pipe I guess the one nearest the filler pipe takes the pipe from the safety valve? by the filler cap. The other connection takes the pipe that leads to the carbon canister (again through a valve?)and travels alongside the brake pipe from back to the front of the car and then up into engine bay. Looking at all this tho I’m now struggling to find any electrical connections to any valves, (which I thought I would have, as Haines manual shows an electrically operated valve and having researched this site and seen reference to a valve that only opens when the engine is warm enough? perhaps,  the later cars didn’t have any). 
 

thanks again.
