Eventually I will be rebuilding my compressor , value block, replacing my air springs etc etc. I'm thinking while I'm at it I should just run all new airlines. With 121k miles on a 2002 how long to the airlines last?
6mm and 4mm. Is it a major PITA? I figure front ones aren't bad but the tears might suck.
Looking for first hand knowledge.
Thanks in advance.

youll no doubt get loads of replies but its easy peasy just make sure you cut ends that are straight and not at an angle

I've gathered the job is not to difficult. Anybody know what length of 6mm hose to get? Do they make a precut length kit? I'm thinking of adding a rover Raiser from Scotty while I'm at it.

The air lines are nylon and don't deteriorate with age. It should outlast the rest of the car.
The ends of the pipe sometimes gets worn or damaged where it pushes into the valve block and air bags. It is easy to cut an inch or two off to get a new seal.
If it doesn't leak, leave it as is and just replace the o-rings. if you need to cut an end off, as mentioned cut it square and also use a pencil sharpener to put a slight chamfer on the pipe so it pushes in easier. Remember also there are two o-rings in each seal.
If the pipe gets a bit short and you need to order tubing it is nylon 6mm OD and 4mm ID. It is not that expensive from a dealer, at least not in the UK. You can use a joiner to lengthen the hose.

The airline hose comes on a reel. You order by the meter/foot. The dealer does not do precut lengths.

It should last forever, I've only replaced ones when they got too short from cutting fresh ends as described. If you don't have that issue and they aren't leaking at the fittings, I wouldn't mess with it.

NorCal,
Agreed. I've learned not to poke the bear. I've got plenty else to worry about. Going to soapy water test again before I create a final parts list unsure of PO work on EAS system but I'm guessing a lot is stock. Gen III air springs and Terrafirmas will be next when the stock stuff goes.
I've got a slow leak in LR but not to bad yet. Just trying to prepare for future problems.

If you are going to buy Gen III's, keep the receipt in a safe place.

Hi All, Thanks for the great info here.

Question for you - How robust have people found the Arnott Gen III bags vs the original OEMS?
I have a full set freshly installed and the ride quality seems improved, particularly rebound. Not sure if this is improved design or simply fresh bags. I am considering adding them to my other P38.

My opinion having run both over many years:

OEM:-
Made by Dunlop. Natural rubber. Thicker wall.
Will perish eventually but usually last 12 years or so +/-.
1 year guarantee?
Better (softer) ride at standard height. Slightly worse (softer) ride on the highway/motorway. Worse (stiffer) ride off road.
More reliable regarding leaks/problems.

Arnott Gen III's:-
Synthetic rubber. Thinner wall.
Won't perish.
Lifetime warranty but depends on country where you live. Need to keep the original receipt otherwise claiming is a problem. Conditions attached.
Slightly worse ride (stiffer) at standard height. Better (stiffer and less roll) on highways/motorways. Much better (softer) off road.
Frequent? leaks, particularly from the top clamp ring.

Not worth getting Gen III's unless you use the truck off road. You will need to extend the sensor arms on the back to give the full 4" lift over standard height.
Dampers need to be changed as well for off road. I am running Terrafirma +2" shocks. This stiffens ride further. Makes it harsher at standard height but far better off road.
Also far better when towing with a heavy nose weight trailer.
If short of money use front Boge dampers all round.

My opinion on the Gen III's is actually quite different. I've been on them for almost 7 years now with 0 issues. The ride quality is great at both highway and offroad settings. I have had 0 leaks from the bags and I live in a desert with very low humidity and high heat (you should see what the sun has done to my tires and paint), with lots of dusty dirt road driving. I think the price is equivalent between the two, so it's just a matter if you want to go OEM and get the ride quality that the RR had from the factory, or something slightly different.

It all depends on what you like.

But the Dunlops are far cheaper, Air Spring Front P38 REB101740 Island 4x4 - Specialists in Land Rover and Range Rover Parts and accessories for all models. UK and worldwide mail order. and Air Spring Rear P38 RKB101460 Island 4x4 - Specialists in Land Rover and Range Rover Parts and accessories for all models. UK and worldwide mail order.

Gen III's are about 5x the price here in the UK. Price is for two:-

https://p38spares.co.uk/commerce/product/1878/Front_Range_Rover_P38_MKII_Generation_III_Arnott_Air_Suspension_Air_Springs_Left_and_Right_1994-2002_x2.html

Might be cheaper in the States.

As I said not worth it unless you go regularly off road and need the extra clearance.
Ride quality at standard height is worse. The stiffer spring rate at this height means it is quite a bit noisier inside the cabin compared with Dunlops.
At motorway and off road heights it is better imho.
