hodge Posted January 28, 2011 Share Posted January 28, 2011 Hi guys Just curious really. I was doing some work on Johnny.G's fuel pump hanger last night where the 3rd small pipe goes as when fitted it seems to disappear down towards the rear drivers wheel. Now the pump hanger has a feed (banjo bolt), push on return (larger of the 2 pipes) and then this small one. The tank breather from the charcol canister attaches to the top of the tank and not the hanger so I'm a bit stumped really. Aftermarket hangers also have this extra pipe but the only difference is the stock hanger has a metal pipe leading down inside the tank from this but aftermarket hangers don't it seems to just be a vent hole of sum sort. Can anyone shed any light on this for me please. Thanks John Quote Link to comment Share on other sites More sharing options...
hodge Posted January 28, 2011 Author Share Posted January 28, 2011 Here's a pic of my fuel hanger mounted in the car. It's the pipe on the left next to the blue fitting that runs across to the right. Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 28, 2011 Share Posted January 28, 2011 I believe it goes off to the petrol cap area, some sort of breather vent there or something. Quote Link to comment Share on other sites More sharing options...
hodge Posted January 28, 2011 Author Share Posted January 28, 2011 Thanks Ian. Any idea why it has a pipe down into the tank and an aftermarket hanger doesn't. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 28, 2011 Share Posted January 28, 2011 It balances pressure in the filler neck and tank, I am told, so opening the filler cap with any fuel pressure in a full tank shouldn't vent fuel over the person opening it. It doesn't really matter if it goes above or below the fuel level in the tank, BELOW may give more protection, I am trying to visualise the levels involved....
