AJP8 Fuel Lines
Discussion
I have the early 4.2 cerb with the fuel hoses that run from the rear of the engine down the inside of the transmission tunnel, today noticed a smell of petrol and a slight weep around the rubber where one of them meets the elbow fitting connected to the fuel rail at the rear of the engine, under the windscreen wiper faring.
Has anyone converted their fuel lines on an early 4.2 to the later setup where solid stainless pipes run inside the cabin?
Can anyone post any pictures of where the solid pipes run and where they enter/exit the cabin?
I guess i am going to have to do it myself as I don't fancy risking driving the car as so many have ended up a puddle of melted plastic due to similar problems.

The fuel lines inside the car enter the car from either rear wheel arch, then turn underneath where the helmet holder is, make their way down the centre console and then straight through the bulkhead. The main line that rus down underneath the car from the rear of the engine on the cross connector which you described is connected to the carbon can in the rear passanger wheel arch.

Regarding the rubber hose running through the transmission tunnel, are you sure you are not referring to the emissions pipe that goes from the manifold cross connector to the carbon ca?
There's a single line on later cars that is the purge line.Early 4.2's appear to have both Feed and return high pressure lines running through the tunnel.......

i'm just having some work done to my fuel tank:here's a pic:
shows where the lines come in and go out

The hose running from the elbow at the rear of the fuel rail is definitely knackered, when the engine bay is good and hot if you squeeze it petrol weeps out, great, so effectively that's me off the road.
I think I am going to do the job myself, need to figure if there is any way I can run new hoses down inside the tunnel or wheter I run solid pipes inside the passenger compartment as in the later cars. The first option is going to be bloody difficult without taking the engine and box out first, the later will involve removing the leather panelling of the transmission tunnel which is probably the lesser of two evils I guess.
Anyone been down this road would be grateful for any tips.

I was digging around behind the helmet holder and under the trim at the front of the console a few weeks ago. It was before you started this thread and unfortunately I didn't take any pictures. However, I will be fiddling about fitting a new earth lead in a week or two and will take some pics for you.
On my 98 4.2 the hard lines come in from opposite sides at the rear - high pressure feed on passenger side and return line on drivers side. They come down the top of the tunnel and have a 90 degree bend to take them behind and parallelto to the back of the rear seats and out through the body work.
At the front they have a number of 90 degree bends to take them up the front bulkhead and out from behindthe front trim, and thence to the bulkhead in front of the passengers knees.
The piece of trim that has the silver switch and immobiliser and ash tray will slide out towards the passenger side. I took it out to have a look at the earth point that is behind there. its the arrangement of the pipes here that you will need a clear pic of.
here is one from Tanquero that shows the earth point with some of the fuel line detail arond the hand brake.
I think you mightjust about get new lines in with the centre console in place lifted at the rear. You would definitly need the rear shelf out, helmet holder out and centre console trim that has the silver switch and the trim panels above the passenger knees out.

Hi,
I have just replaced all my fuel lines. I used braided steel hoses and ran them through the cabin under the central console to be away from the exhaust heat. It was an easy install but I recommend that when you seal around the hoses through the bulkheads/body fornt and rear that you use intumescant mastic. You can get it at most good builders merchants.
