Oiwa Garage Tech Note
"These get brittle with age and the nipples snap off. If you find hoses dangling with nowhere to go, this switch is why. Photograph the hose routing before you pull it."
Frequently Asked Questions
How do I know it is bad?
The plastic tips go brittle and break. If vacuum hoses are hanging loose with broken nipples, the switch needs replacing.
Carbureted or fuel injected?
This is for carbureted engines only. Confirm yours is carbureted.
Will it fix my idle?
If a broken vacuum switch is the cause, replacing it and restoring the hose routing brings the signal back.
