I had an auxiliary Long Range America tank recently installed. The installer is not a Land Rover mechanic but is the installer recommended by the manufacturer. I feel comfortable that they did a good job and are being honest with me and have so since the start about their Land Rover knowledge.

That said I’m getting a check engine light with a code for a leak. P0442. They have smoke tested the setup and can’t find a leak anywhere. They think that they truck is pulling a vacuum on the fuel tank to check for leaks and throwing the code when it times out as there is much more capacity on the two tanks so the truck does not expect there to be that much time to go by. I’ve filled both tanks up when first installed and the code started right from the get go. We are checking with the manufacturer for answers.

Has anyone here installed/had installed this tank and had this issue?

Anyone have any thoughts on the truck pulling a vacuum on the fuel tank?

I had a fuel cap leak and with some fiddling of the cap and a full auxiliary tank and an almost empty main tank the code went away. It has been less than a day, so we'll see how things go.
