Dont waste your time.
The check valve i recieved offers no different resistance one way from the other. I got into a project and spent a lot of time putting together a tank and the electronics to run and monitor the pump, then opened this bad boy and it was garbage. I then went to see about a refund and the price isnt wotth the effort. Do not waste your time on this.

Vacuum check valve
This is an item that I used to get the vacuum heater valve to work. It actually works to block the vacuum from slacking off when the manifold vacuum slacks off under acceleration. The item was delivered, as I have come to expect from Amazon, ahead of schedule and in good condition. Thanks, I needed it.

Need more info on the description
I was able to make this work on my vehicle by creating a bushing out of a couple pieces of small diameter hoses on the smaller side of the check valve. Luckily, the other side was the correct size. How hard would it be to add the size of the fittings in the product description or additional details? Especially since it says right on the packaging....

You can't get the discontinued Corvette vacuum harness--which is the only way to get the check valve that breaks. This works. I have a big cam so I don't know how much vacuum it restricts.

Works but doesn't quite fit properly without some assistance
Needed a new check valve to fix HVAC on the ole jeep. This did technically fix it but due to not having flare on white end I had to use a zip tie to get it to stay working. This would be better as universal if it had a flare since if needed you can cut off the flare (*cant add one) :) . Would I buy again, .. probably not, would probably find a different one with the flare to properly set and seal without modifying.

Nipple diameter is tiny and has to be built up to fit Vacuum tube, Could also use a flange to keep the tube from sliding off.
