Just to round this off, below is a photos showing the airtank and the fuel lines, even Land rover would not be daft enough to put plastic fuel lines over or adjacent to to hot exhaust-:

From the next photo, you can see that 2 of the EAS air lines go forward, one directly to the N/S front air bag, the other carries on forward and crosses the front of the car behind the RAD for the O/S airbag. You can also see the bundle containing the other 3 pipes disappearing down in front of the bulkhead, I can feel all 3 pipes along the top of the chassis but it is impossible to take a photo, the lines for the tank and the O/S airbag go across the rear cross member. I have one left hand drive and two right hand drive P38's, the layout same on all three.

I found the EAS fault, corroded connector on the front O/S height sensor, the readings would jump from a sensible figure to as high as 180 as the suspension moved. Cleaned up the connector and it looks good, need to check the calibration but battery flat on my laptop.
