    Re: The vent from my tank

    Does your tank look like this?

    The fuel tank must be fitted with a vent (to permit release of a pressure build up) which does not exit on to the exhaust or into the vehicle or be situated at such a height that fuel would be likely to leak when the vehicle is driven.

        Can it not be placed alongside the suspension shocker etc , I located the vet on my Berly there, with the air exit about the same height as the filler, previously could only use about 80% tank capacity because of the sloshing about of fuel and it escaping via the breather.

          One of these valves at the top of the breather pipe should help. Peter

            I think Jean is asking "how to remove the fuel tank" from the car.

            It depends on how the car was built! On some Mk 2 Roadsters the tank was fitted from below, on others from above. The build manuals were non specific, but suggest that the tank is fitted before the body.
            If it is fitted from below it should drop out once the clamp angle has been removed, if it is fitted from above, the whole rear bodywork has to be removed, for access, unless there is an easier method that I don't know about.

                  The only standard in the UK is, as already said "The fuel tank must be fitted with a vent (to permit release of a pressure build up) which does not exit on to the exhaust or into the vehicle or be situated at such a height that fuel would be likely to leak when the vehicle is driven."

                  The use of one of these would be a bonus.

                    Re: The vent from my tank

                    I looped min around the top of the fuel filler neck and back down across to the passenger side of the car through a hole drilled low down in the back of the tub. There is a thread in the build diary section that has pictures from when I replaced my tank. I tried a non-return valve at the end of the pipe but it does not all the air to escape while filling so I couldn't get a full fill. My next upgrade would be to add a couple of small pipes to the filler neck to join the breather to the tank from and a non-return valve on the other so I can get the benifit of a full fill and have the non-return valve preventing fumes from escaping.

                      Have a look at post #25. It might give you some ideas.
