will this fit a 96 pontiac grand am 2.4l ?

Any check valve that will fit in the vacuum line will work, IF IT WORKS THIS ONE DOES NOT IT IS JUNK. Get ACDelco 14047619 GM Original Equipment Cruise Control Vacuum Harness Check Valve I GOT THIS ONE AND TESTED IT IT WORKS !!! get adapters to fit in in if you must but this one works. 4 or so of 5 items I have got from Dorman did not work, I called the corporate offices and told them, perhaps the bean counters did not know how bad their products are, to date they still produce junk do not buy it!

In Amazon's war against reasonable product descriptions, they have left off the fitting sizes! The black end looks bigger in the pic. Is this 1/8" ?

The black end is 1/4" and the white end is 1/8".

What diameter are those nipples? Can you put a caliper on those nipples to measure the outer diameter please?

the smaller end is 3.7mm the other is 6.3mm

Will this fit 99 ram 1500 4x4

This is a universal valve. Here are the OD of the 2 ports. the smaller end is 3.7mm the other is 6.3mm
