As long as I was evaluating all the air compressors I had around I figured I’d try some tests on these tiny ones..
I think most are from automatic blood pressure meters.. They can build a decent amount of pressure.
except for this guy. he’s from a Hyundai emissions canister. It was in the evap canister and I think its just bad. I haven’t got my hands on another one yet to compare it to. the car was throwing a code foe a fuel tank leak. I think the little guy just couldn’t pressurize the fuel tank….
