I have removed all of the set up from my car but have one question in terms of safety.

The pipe from the top of the fuel tank..

I didn't want to just block it off as I was worried about the tank pressurising and hissing when you take the fuel cap out and I didn't want to leave it unblocked either as worst case senerio if I flippd the car then the fuel will pour out.. not good

So.. would it be ok to fit a one way valve so that it lets air in and nothing out? so hopefully when taking the cap out it draws air in and stops the hiss?

Or.. do fuel tank need to breath out at all?? I have no idea?

Anyhelp would be great on this

Thanks Paul

You the man

 

Paul, I use one of these on the Westy and works fine, even on track.

 

I'm just thinking, there was a verticle valve thingy by the fuel filler neck as standard thats probably what this is maybe I'll refit that and unplug it after that valve instead

I get a pic of it
