[blown 68]

hey folks, i am coming up dry here, maybe someone has an angle for me.......

i need a 3 port vacuum switch, or solenoid valve, that is 12 volt actuated. i cannot seem to find anything, i found one source, but they wanted a minimum order of 500! anyway, any air/valve/switch will do, but it has to be of the nature to not need 'pressure' to activate the poppet. i have an SMC connection through work, but all of the solenoid valves i could find needed at least 6 psi to activate. so, if anyone has any bright ideas, i am all ears for links, ideas, etc. oh, the premise is that this will be inline from my manifold to the vacuum advance can, with a micro switch opening it in any position that is 'off idle' via the carb linkage, ala 'ported source style', and will bleed off the vacuum when in the normally closed position when the linkage comes back to home, or 'idle', to disengage the advance.........

thanks folks!!!!!

ps, ported carb source is no good, blower creates too much vacuum up top, needs to be boost referenced from the manifold........

I think in the 80s there were electricaly actuated switches for vacuum in gm cars for emmisions. maybe a machanic will chime in.

Are you talking about your power brakes? If it were me, I would slide down to NAPA, get a manual brake master cylinder and move the actuator rod to the other position on the pedal.

Most brake pedals have a hole for the power brake position (about 5:1 pedal ratio) and another hole for the manual (about 6.5:1 ratio.)

Of course, if you are not talking about your brakes, please disregard...

Hows that rig runnin??
