1979 C3 Air Cleaner Assembly - plumbing

(1/2) > >>

stuclark:
I have '79 C3 with L48 engine but the standard twin snorkel air cleaner assembly. The picture is not my engine bay, but shows the assembly I mean. my question is..on the underside there is a small diameter vacuum line that goes onto the engine or somewhere to get a vacuum from. The 2 air intake valves for the exhaust hot air input are in place and work. But this one hose has broken off somewhere and I cannot find where it goes? I cannot hear leaking vacuum. Does anyone have a standard '79 with this configuration that can tell me where this goes?

sirfixalot:
Will have a look tomorrow arvo

Mine is a 78 but I  think they are sameish. One hose goes from the top (hot air valve as per the pic) under to the thermostat, then a second hose goes down to a port on the base of the Quady. I can't  remember which side and I  can't look as I'll wake up all the mice and chickens. You may not hear anything as people remove these thinking they get better performance, (COS) this device ensures the engine comes up to temp quickly by drawing air from over the manifold, once hot the thermostat switches out. You may find carby port capped or plugged. Having said all that if you don't have the hot tube and the manifold heat stove cover - then its a fait au comple.

Vettech:
Yes I  think it is at the front of the carby (Quady) below the choke feed pipe - Oh and did you know that the Quady has a little itsy bitsy  fuel filter in the carby  at the fuel pipe entry port. You need two spanners be carefull not to twist the pipe. Have fun. (Please remember that I'm  using knowledge  of a 78 but they should be the same or close.)

sabre:
Unless it changed between 78 & 79, the pictured air cleaner is from an L82. The L48 had a single inlet. I came across this in the assembly manuals when I was putting my anniversary model back to factory.
This doesn't answer your question but might help if you start looking for vacuum diagrams.
