My memory might be failing but since when did the tank feed pipe go near the rear axle? The three pipes feeding the O/S and N/S bags and the tank, go across from N/S to O/S below the transmission tunnel. They then go along the chassis frame. Tank feed goes to tank in front of fuel tank. Other two carry on along chassis, one directly to O/S bag the other then goes up and across in body recess to N/S then forwards to feed N/S bag. Feed for tank does not go near rear axle.

On mine, the pipe to the tank goes along the left chassis rail then across the rear cross member and forward along the right hand chassis member into the rear of the air tank. Ask me how i know this

Can't say i noticed that on mine why on earth would they run a pipe almost to the back of the car then back halfway along it to the tank. Both feed lines to the rear bags most certainly cross over and run down the O/S of the car.

Not noticed any air lines on the right hand chassis leg apart from the short run forward from the cross member to the air tank. Where do the other air lines cross over?
I will have the 99 car in the barn tomorrow if it's raining to do a height sensor, so I can have a good look at where the pipes are on that.
For clarity, the left hand chassis leg is the side where the EAS box is in my description.

They run along the top of the O/S chassis leg. One to the O/S bag and then the other one across along the same channel as the brake pipe out and back along the top of N/S chassis leg to the N/S bag.

So, the EAS box being on the near side and the bundle of pipes disappearing down under the bulkhead, where do they cross over to the offside?

In the transmission tunnel as far as i know but they defiantly run along the O/S chassis leg top. Cannot see why as said, they would run a pipe along the N/S to the back then across and back halfway down the O/S to the tank. Maybe you have confused fuel lines they run down the N/S chassis.

No confusion, the fuel lines are clipped to the floor of the body tight to the air tank then disappear between the fuel tank and body. The air line from the rear of the tank is clipped to the inner side of the chassis rail until it reaches roughly the intermediate brake line flexi area when it goes up over the cross member.

Check tomorrow and confirm. Fuel lines run up N/S nowhere near air tank.

Cheers warmmers was thinking why do they go all that way I will check it the wkend

Sorry if I got it wrong but my feed to tank goes up the n/s chassis, across above the back axle inside a conduit type thing as part of the body and then down the o/s chassis to the tank. Mine may be unique, but that is the ppe that I had to replace as I couldnt fill my tank due to exhaust leaking. Its not an offiical conduit but it is in a box etion which hides it so you cant check for leaks.
Why did they run the pipe this way for my vehicle??? Havent a clue

My fuel lines run down o/s chassis or at least the pipes that have the fuel filter in do that
Mine is a V8 if that makes a difference .
Tractors may be different,

Fuel lines on all 3 of mine run on the offside close to the airtank, I will take photos when I get the car into the barn.

I must be dreaming then, sure i was under N/S to disconnect quick links. Not fit enough to go and check so will have to think i was mistaken. Happens a lot these days.

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.

Cheers Keith

That seems about right then Keith, when i did the bags didn't pay much attention to pipe runs just unplugged and refitted. When i did the in tank pump and brake pipes got the impression that the pipe that went past the O/S bag was to the N/S bag obviously it is the pipe running to the air tank. But what a silly way of doing it. All the way along then over and halfway back down the car. When all they needed to do was run it with the O/S pipe and loop it back into the tank. Fuel lines seem to be as you say don't know where the N/S run came into it.

No all are same it would appear just me getting my to's and from's mixed up. Do wonder about the routing. I mean why would you drive all the way to Glasgow from Preston then turn round and drive half way back to get to Carlisle. Sorry.

Not a problem and to be fair if I remember correctly it was you that told me that the exhaust had melted my pipe a few years ago
And I am so chuffed to have got it right
