    Outlet spigot I guess.
    Can be drained and repaired though depending on how fubarred it is.
     
  2. It's would appear to have some form of piping clipped over it and maybe some glue? :-(


    I have not seen it myself but the mechanic who inspected the van when we broke down was far from impressed with it!

    On yours i think not, but there is a stubby bit that the rubber pipe connects to-

  5. Not roundabout specific, so hope this isn't considered a thread jacking!

    I hope you can help me identify what is going on in my engine bay in relation to fuel lines & breather pipes.

    Copper fuel line enters engine bay through a rubber grommet (good), although the pipe is easily moveable up & down.
    1. Copper pipe joined to rubber fuel line
    2. Fuel filter joins to another rubber pipe leading to...
    3. ...Fuel pump (I assume)
    4. Pipe from fuel pump to both carbs, (only one side is labelled 4) is the braided stuff. Is this correct or should it be changed for r9 rated fuel pipe? If so what size pipe please?
    5. Breather pipes: Copper pipe at top of engine bay (painted red) from both sides, goes into a t piece, it breathes into rubber pipe from breather box to left hand carb.
    6. To the right of number 6 is a braided pipe where copper pipe passes through metal. I can't tell if this pipe is just to protect the copper pipe from rubbing or is actually a join connecting two ends of copper pipe. Any thoughts?, I've felt the braided thing as best I can, but can't tell.

    Behind the internal spare wheel well (not in the photo) Edit: after seeing the picture above I have now found that 'pipe' it seems to be the old braided stuff and is covered in waxoyl! Is it essential I change it to R9 pipe? & is it possible to do by taking the light unit out (I'm crap at this sort of stuff).

    My engine has just been out and I asked the engine builder to change all the pipes behind the firewall, I know he didn't change the rubber fuel tank pipes, but did tell me they were in good condition.

    Thanks

    Personally I'd do away with the over-braided stuff. You can't see when its perishing until it spunks fuel over your engine. I also personally wouldn't have a fuel filter in the engine bay.
    To check the connection behind the spare wheel well, take the near side rear light cluster out and peer through the ideally placed hole!

  7. A potential newbie question here, but my breather system doesn't go back into an air filter in the main engine compartment, it is just blocked off as far as I can see. So, in Poptop2's pic above, part 15 is connected to the two hoses at the top of the engine compartment, but the exit of that T-piece that goes back to the engine has a stopper in it and the parts 27, 9, and 28 just don't exist.

    Wiggie is a 72 crossover, with a 2 litre Type IV engine fitted years after manufacture, and Weber twin carbs in case that matters (I assume it does as I don't think I have an air filter for it to go back into because of the twin carbs?).

    Is this correct? Shoud I be worried about it?
     
  8. I think it must be parts 24 he is talking about?

    Are these fixed to the tank or can they be replaced?

    He said a new tank would come with them fitted?

    I should ring him and ask. The list was that long I got very confused with it!
     
  9. 24 is the breathers lol

    I will have a look at the paperwork when I'm home!

    i have seen this before on twin carbs not sure it is the best way to do it tbh but not sure where else you could put the breather if the air filters have no connector?

    Looking at paulcalfs picture he seems to have the breather going into the top of his air filter!

    Just plumb it into one of the air filters with a plastic / brass union.

  13. yeah I've just had that done, the t piece 'outlet' goes to the pipe from the breather box to the air filter on top of left hand carb.

    Sorted then :thumbsup:

    That is the way to do it surfgirl :)

  15. Baysearcher thanks for the advice. Do you know what size the fuel line is please?
    Just inspected the fuel filter and it does seem to have a tiny bit of petrol seeping out near the join with the rubber pipe leading to the pump!
    I've just found the pipe behind the spare wheelwell, it is old!
    Any ideas on braided pipe numbered 6 in my picture?

    Thanks again!

    No worries. Stock was 5.6mm i/d on a type 1 I believe. Make sure to use proper fuel line clips, not jubilees.
    No.6 I would GUESS is just a piece of sacrificial hose to protect the metal pipe. Maybe try to cut it with a Stanley knife. You can always replace it.

    Replace the 2 pieces of over-braided between the entry into the engine bay and the fuel pump with 1 continuous piece and put the filter above the gearbox in the length between tank and metal hose to engine bay.

  18. Isn't 5.6mm i/d just for the breather pipes, rather than the fuel line? With you on proper fuel line clips rather than jubilee.
    Great idea about cutting braided pipe on No 6 photo!

    The 2 overbraided are from fuel pump to carbs, but i'll arrange to get them done and i'll look at moving fuel filter to between tank & gearbox - although i'll never see if it is leaking there!

    Nope, 5.6mm is fuel line too. Cool Air sell it.
    Get rid of all the over-braided stuff, its Marmitee.
    Do it yourself, it'll take less than an hour including quadruple checking you've tightened all the fuel line clips. That way you know its been done properly. Buy a fuel line clamp and clamp it under the bus before you start so you don't empty the tank over yourself. Catch the small amount in the lines in the engine bay in a bottle, then change them until your hearts content.
    Or pay someone else to do it but it really is one of the simplest jobs.
    :)
