Took the Cerb for a run to Brands on Saturday , ran very well, however when I opened the window at the toll noticed a strong fuel smell from the engine. Doesn't appear to be any leaks or fuel loss , just wondered if this is common on the Sp6 when nicely warmed up ? Cheers. Dazza.
Check your fuel lines very carefully before using the car again! There should not be a smell of fuel with any model. Mine went right under the expansion tank where the junction is crimped onto the flexible hose and sprayed fuel across the exhaust. I still can't fathom how I avoided a fire. 
There was a faint fuel whiff for a few days with nothing to see at all before it went completely. If in doubt change the hoses.

+1 There was a faint fuel whiff for a few days with nothing to see at all before it went completely. If in doubt change the hoses.Thats where mine failed,, as already stated,, you should nt be able to smell fuel.

Are they easy to locate and replace ? There was a faint fuel whiff for a few days with nothing to see at all before it went completely. If in doubt change the hoses.

As I've got my cerb in bits right now, I've seen these under the expansion tank. Now on mine only one of them is connected up, which is the return from the fuel rail pressure regulator. Apart from running the fuel hose along the transmission tunnel back to the fuel pump/filter, is there any reason why mine is different??djstevec said:

Not sure that I follow you. 
Most Cerbs have two hard lines running inside the car. One from the near side wheel arch from the fuel pump and one from the off side wheel arch which is the return to the tank. They come into the car on the inside of the wheel arches and meet inside under the helmet holder then run together along the to of the transmission tunnel under the console and exit into the engine bay unser the expansion tank. From the two hard lines there, there is a fuel hose that joins onto each of them with a compression coupling. One fuel line goes to the fuel rail (from the pump) and the other is the return line back to the tank.
I believe that some early Cerbs had a different arrangement involving flexible hoses inside the transmission tunnel, but I can't tell you the details.
If yours has 2 hard lines then they should both be connected. If you have one hard line and one flexible one inside the tunnel then I guess yours is one of the early ones. Though mine is a 97 car too and it has the 2 hard lines.

I have two normal flexi hoses running backward to the rear along the pax side of the bulkhead heat shielding. One connects direclty to the fuel cooler and the other from the 4 way cross piece.
Its a 97 too.

The hard lines are steel rather than copper so they may be rather more susceptible to fatigue fractures which might be a reason one of yours was bypassed.

My guess would be that yours is a non standard arrangement. Possibly there is a split or leak in one of your hard lines and it has been bypassed at some time. The hose from the 4 way is not a fuel hose - it is the vacuum hose for the carbon canister purge system which sits above the fuel filter in the near side wheel arch. That is present on all Cerbs I think. The hose to the cooler is bypassing the hard return line.

Quite a lot of this car in non-standard!! But I wont be hooking up the unused outlet to find out either. Will protect the fuel line a little better though.The hard lines are steel rather than copper so they may be rather more susceptible to fatigue fractures which might be a reason one of yours was bypassed.
