The question is where to get emission control components. Does anyone
know of some
vehicle that uses a small solenoid valve, about 1/4" or so port size?
What about a 2 PSI valve?
Details: I'd like to replace a "Rochester" valve used in a Jaguar fuel
vent system with something more reliable. This valve is designed a
a valve that relieves tank pressure greater than 2 PSI, allows
relative free flow back to the tank
under conditions of falling tank pressure, and allows unrestricted
flow when the engine is running.
The latter is detected by manifold vacuum. This is in the fuel tank
vent line that feeds vapor to the charcoal
canister. The problem is it's a notoriously unreliable device, and one
is always uncertain if it's working.
I'm thinking about replacing it with a solenoid operated valve in
parallel with a 2 PSI valve. The solenoid will open when the
ignition is on. Otherwise, the 2 PSI valve vents tank pressure above
2 PSI, and allows free flow into the tank
if the tank pressure drops below atmospheric.
So, where can I get a 1/4" solenoid valve and a 2 PS valve? I'm
hoping someone will know
of some GM year/model that I can search junk yards for, or step up to
the dealer's parts counter with
a part number.
