Dellortos and various hoses 

Posted By : Paul Bodiam, 19-Dec-2003, 02:23pm

I've recently acquired a set of Dellorto carbs and manifolds for my 1500. (see picture) Mmmm...

Some questions for anyone who has Webers or Dellortos already fitted to a 1500:

1) How do you deal with the hoses that used to route hot water through the inlet manifold?
Do I have to run a new hose replacing the section that went through the manifold, or can this be blanked off at each end without affecting the circulation of coolant?

2) How do you connect the vacuum advance into the manifold? Or should I switch to a dizzy without vacuum advance?
NB: this car is being built for exciting road driving, not for screaming round the track at 7000 RPM !

3) What should I do with the rocker cover breather? This is currently connected to both SU's via a T-piece and hoses. Should I try to connect it in some way to air-filter side of the Dellortos?

thanks in advance

Paul

  Paul,
  For the manifold hoses you can just blank them off without any problems.
  
  Vacuum advance, well if you want to have that you'll have to drill and tap the manifold appropriately or as you have said get a dizzy that doesn't have a vac advance or modifiy your existing dizzy to compensate.
  
  Rocker cover breather, well you can either route it into a catch tank or down to the road (not on a racer). If you have to re-connect it then to should be after the carburettor not before it, but again this will require drilling and tapping your manifold.
  
  Cheers

    Hi NiG
    
    Thanks for the advice.
    
    Since posting my original message, I've had another look at the routing of the various coolant pipes. The one running through the manifold appears to serve as the return from the heater, so if I blank this off, I think the heater will stop working. brrrr...
