Hi all
Just been out for a hoon today (good times) and the cabin was full of the smell of fuel (bad times). Had a look under the car and fuel was gushing out from the back but the exhaust was too hot for me to see where it was leaking from (yes I know, this now sounds very stupid and dangerous!).
It looks like it might be coming from either here :
(this is under the body, near the exhuast)
Or here :
(passenger side rear wheel arch, you can see the suspension in the picture).
Couple of questions:
Are these both fuel filters? If so, am I likely to be able to get them from the local motor factors/Halfords?
Its an early 4.2 car, so I should replace as much rubber hose as I can, in which case, does anyone know what diameter they are please?
Many thanks (as always!)

The second picture is definately the fuel filter.
If you had just filled up with petrol the usual cause of leaking under the car is the carbon canister getting saturated with overflow fuel so that the tank won't vent correctly.
I would strongly suggest that you get the correct fuel hoses from one of the specialist suppliers : TVR Power, Clever Trevor, Racing Green etc. rather than making do with generic ones. Cerbs seem to burn rather well - it would be a shame to lose another one for the sake of the correct hose.

I thought the pump was on the bottom chassis rail, the filter was upright a bit further up (might have got those two the wrong way around), and the carbon canister was right up at the top of the wheel arch area.
This is right. The first pic is the fuel pump.If I were you I would get a load of degreaser and clean all the crap from that whole area then you will be able to see whats going on. The pipes may well have cracked with age and won't necessarily be leaking at the joins.
Well, that was fun!
I replaced the fuel filter (thanks again for the info chaps!) and it turns out it was the line from the filter to the front of the car that had perished.
That's right, its an early 96 4.2 so looks like that will be a fun job to replace!
Quick question, where does the fuel line that runs to the engine back actually end/terminate? Just trying to get an idea of length required and diameter of the hose. Think I'll be going for braided this time!

Follow the rubber line from the fuel filter, it connects to a solid line just before it goes into the car. Should be just behind the rear seat. The solid line then appears again on the passenger side of the transmission tunnel.
One question I have which is quite related, the rubber hose that connects to the solid line at the engine end, mine appears to have a metal collar. How do you take this hose off? I've tried pulling to little avail, I'm guessing this collar is a one time fixing and to get it off you have to saw it off?

See half way down the page on my rebuild thread. I had to replace the hoses due to perishing...http://www.pistonheads.com/gassing/topic.asp?h=0&a...
On early Cerbs (like mine), the fuel pipes run along the inside of the transmission tunnel and don't go inside the cabin like on the later ones. It is true that most of the section is copper pipe as standard. You will need to remove the aluminium heat shield and perhaps drop the gearbox off its mounts a bit in order to remove and refit a new line. Cleary the new fuel line should be heat insulated as it resides in the transmission tunnel.
Thanks for the advice and pictures chaps. So far, I have not had the car up in the air and apart to look in detail so sorry if these are lame questions.
As far as I understand it, there are several lengths of rubber hose that connect to the copper hard pipe. ALl of the unions I have seen so far are jubilee clipped on so I guess I should just grab a load of 8mm? fuel hosing, new jubilee clips and heat shielding.
Sound about right?

No. You need the correct fittings. The hose to that fits to the hard line is a compression fitting. If you look at the picture above you can see it has two sets of flats at the end. Turn one against the other and it unscrews and releases from the steel fuel line.As far as I understand it, there are several lengths of rubber hose that connect to the copper hard pipe.

Baz, first thing you need to do if get the car up on a ramp and identify where the leak is, if its a early cerb, 96-97 as already mentioned, then the fuel lines are copper running inside the transmission tunnel, with flexible rubber pipes bonded at the ends, it gets worse, they are cable tied to the top of the tunnel to the chassis tubes, which makes them very difficult to get at, you will need to remove the exhausts and cats and the heat sheild above. If you have a later car the fuel lines run inside the cabin along the top of the transmission tunnel as steel tubes with compression fittings, which means you only have to replace the rubber hoses at each end.
If it the first case let me know and i will post some pictures of how I did mine, however it was not an easy job.
