Hi all Is this bronze/copper coloured pipe doing anything in the fuel line? My fuel line is to long and could easily be shortened but means removing this. Can I remove or does it do something I am not aware of? Thanks.  |

THE PIPE WITH COPPER JOINING SECTION LOOKS LIKE A BREATHER NOT STANDARD BUT YOU ARE PROBABLY AWARE OF THIS,IF THE OTHER COPPER PIPE IN THE PHOTO IS A FUEL PIPE IT SHOULD ENTER THE FRONT CARB.

Thank you for the reply. So the breather is needed or can it be removed? The fuel line does go the front carb. But it goes on a journey before it gets there and doesn't look very neat. I was hoping to remove the copper join and shorten it's journey........ |

For the avoidance of doubt this is the pipe I want to remove.  |

Hi DLM,
I would get rid of that copper pipe - it doesn't appear to do anything.
Your fuel pipe should attach to the front carb like this ....  The fixed fuel pipe runs around the horn and then has a flexi pipe to the carb (just above the horn in the picture).I normally fit the fuel filter in the middle of this flexi pipe.
With the air filters you have, you should have a breather pipe going from the top of the rocker cover to one of the filters. This is to allow the engine to breath, but not allow any of the oily fumes to escape (i.e they get recycled into the engine!).
Trust this helps,
Roger |

Roger Roger that's perfect and exactly how I want to route the fuel line and add filter. Why it goes of to the back of the engine bay and then back again I have no idea! Thank all.  |

Hello DLM, In your other 'rebuild thread' I mentioned crankcase breathing. Below adds information to the good photo of fuel line routing from Roger and shows an inline filter installed. This photo also shows the breather from rocker box to front air cleaner. For this crankcase vent to work your need the tappet gallery vent as I showed in your 'rebuild thread' post. One without the other is not a good idea.  
FWIW I do not like to see electrical wires tye wrapped to a fuel line. Something about that combination makes me uneasy.

Yes as I say that's the route I'd like to take for the fuel line. Which would also remove the wiring attached to the fuel line.
I'm sure I have a breather, combined with a draft tube as I checked when you posted in my other thread.
I'll have to get a better picture up to see what you guys think.
I can confirm the engine is an 1800 from an MG(?) I believe.
I'm probably getting confused with the point you are trying to make though!

Sorry for the confusion and was not my intention. My point is this; efficient crankcase ventilation is critical to the well being of the engine. I see and read about many poorly vented engines that suffer badly. What you write appears that all is well. I will probably use a PCV valve on the manifold with a tappet gallery vent rather than the draught tube. Of course I will need to use a non vented cap & rocker cover.
Salut Bruce

No need to apologise, the confusion is my lack of understanding of these cars and all help appreciated. |

Bruce Also ...... What filters are those please and will they fit my carbs?  |

Hello DLM Have a look at the other thread you have going about air filters. I tried to explain them on that post.
