This doctor saved many lives. He uses a different treatment method than most. Worth a shot.

I have a rock chip in mine, waiting for insurance to contact me about repair.

The picture is from the service manual: 2016 Defender series 2016 (219 100 834) and I bought the supplement Defender series 2018 (219 100 901). I bought these for my 2019 Defender XT cab HD10 from the dealer he ordered them for me. 

They may have discontinued the printed ones so you might see if you can find the BRP link on line in the  owners section, I believe they are still available but in digital form only, Perhaps someone can provide you the link if they have it?🙂

Thanks. I need one for a 21 Limited.

Go new unless you know the previous owner.

I have attached a picture from the manual to help clarify what we are looking at since it labels the parts.

1) Under the box that has the number 2 next to the tie wrap is the pressure relief valve that has a directional arrow on it. It is supposed to release pressure build up between 0.36 and 1.1 psi. When the pressure starts to build as the fuel warms up and starts to expand the check valve #1 (it is directional) will close to prevent fuel spillage out of the air inlet line. The pressure valve opens and lets the vapor escape to normalize pressure in the tank. The vapors go out through the line up over the air intake box and down under the right rear corner of the cab. This may be why some people smell gasoline fumes occasionally.

2) After the Y in the tubing (to the left) the first round object is the air inlet check valve and the other cylindrical white object is the air inlet filter. Both the relief line and the inlet line run together until the top of the air filter box in my machine and the air inlet filter is mounted right next to the air inlet for the air box.The air inlet filter is at this height to prevent accidental water ingestion into the fuel system and should flow in either direction but cannot allow air in when the inlet check valve is closed.

3) The air inlet system will allow air flow in at any time except when the inlet check valve closes  because of pressure build up in the tank. If the inlet check valve failed in the closed position the air would not flow into the tank when it was cool outside or we were using enough fuel to create a vacuum in the tank. Visually check both lines to make sure they are not kinked where they are held by tie wraps.

4) If the pressure relief valve is not working correctly and releases pressure above recommended maximum the result will be increased pressure on the fuel pump and tank components and increased pressure at the fuel pump which may be a factor in shortened service life of the pump???

5) If you are having concerns about the fuel system the easiest check is to pay attention when you open the filler cap to see if there is a puff of pressure or a sucking sound, an indication of a vaccum. Pretty wordy but hopefully helpful?😉

Is this picture from a service manual? Where can I get one?
