Yes mate, they allow air into the tank so that as the petrol drops as its being used, it doesn't cause a vaccum. Be superb if that's all that's causing the problem! Mega cheap fix! Do try it the next time it plays up though to make sure. Does it do the fault every time you drive the car?

I think you're onto something! After I read this I remembered that many times when I'm going to remove the fuel cap I hear a lot of air leaving the tank (I think it's coming out because I can smell petrol). Today I went for a drive and after I parked the car for a while, removed the fuel cap and heard the rushing air, started the car and it started immediately, but didn't tried to start before removing the cap... Apparently the tank isn't "breathing", the fuel cap has some holes in the middle but when I tried to blow trough them I couldn't at all. Do you know the function of those holes is to allow air in and out? Thanks

Long time since I’ve been on here I still have my civic and spent more money on her including coil overs, new wheels, 3” exhaust system and quite a few other changes the red stickers on the bottom picture have been removed after the photo.
