check valve
I finally had to buy what I thought wa the right one, never did get any to tell me what the parts exact number was.
I found a sight that has a check valve, that said it would fit the following vehicles. My truck a 2 door reg cab was not listed, but a two door extended cab was. Both trucks had 302's but it would not list a two door reg cab just the two door extended. I wrote to them and said they had to be kidding with this, but never heard nothing back.
I found another site that has a 96,95,94,92 but no 93, the price was 27 dollars. I called them up, and asked them what happend to the 93 year left out of there list. they said that part wouild not fit my truck but he could get one for me for 43 dollars, what a sham. I think that when I listed that I had a 93 they did this bait and switch to see if I would be that dumb. Has anyone else experienced this. This was a seller on E-bay
EDIT: One check valve runs from the head to the combined Air Diverter/Bypass valve and the other check valve runs to the catalytic converter. The upper valve is larger, at least it is on my '92 302, Supercab.
All brands were listed the same, even for Motorcraft.
They list two check valves, one threaded, one without threading. The item numbers are 37 and 39. One of those should be what you are looking. FWIW the model years these are supposed to fit is listed for 1985 through 1996.
PCI Inc. is usually pretty good to deal with. I have called them a few times to verify the parts I needed as well as availability. Great service!
I know there is two check valves on the truck, the one on mine that is missing is the one in behind the manifold nearest to the fire wall, of course, the one you can barely get to or see,
Again thanks.
