specs for green & black check valve
 

Should I be able to blow in the direction of the arrow ?

If not, should it be replaced ? Can it be replaced with the white and green check valves ?

With a Mity-Vac it will hold 25-psi vaccum, and will pass air pressure in the direction of the arrow at 3-psi.

Thanks,

Yep, air travels in the direction of the arrow. The stock valves need a few PSI to crack open - they're not SUPER easy to blow through. Mazda specs the white and green check valves for all 4 check valves now.

Don't you have a set of my check valves? Just toss those in and be done with it :).

Thanks again Dale.

Yes, I have four (4) of your check-valves, but my VITON hose is too big!!! It's OK all my check-valves *checked* out good, and they should, I replaced ALL of them less than two months ago!

What size is the hose? 3.5mm silicone line fits those valves well, and using 2 zip-ties to secure it makes it SUPER secure.

Unfortunately, I have 4.0mm VITON hose.
