Don’t purchase this valve, a waste of time and money

I purchased this before reading all of the reviews. Don’t purchase this, a waste of time and money. Vacuum coming into the valve on my truck is 18 but only 10 coming out which is not enough to shift the 4 wheel locking hubs. When tested no leaks because gage hooked directly to the valve so these are accurate reading. I did not send the valve back because based on other reviews would be a waste of time. Don’t try to save money by purchasing this valve, pay more and get something that works.
