Where is the BVSV valve located?

Not Joe but hopefully I can help with this valve.

Are you saying you can't find it to replace it, or you can't find one to buy it?

I ran a quick search and found this one but please make sure the fitment is correct even though it appears it is.

Also, just to be sure it needs to be replaced I am attaching the testing that you can run and find out.

Let me know if I misunderstood. Thanks

Got it. Thanks for the reminder of the different engine.

Looks like the first is called a ported vacuum switch and is used for fuel pressure control.

Here is a link to one that I found:

I attached info below on this one.

Can you give me a little more detail on the second one? Maybe try to see what the valve is connected to. Is it an exhaust tube or where does the tube run to?

I am just not finding anything on the front of the engine that looks like this, so I am not sure yet. If we know what this is connected to then I will have a better idea what it could be. Clearly it is a vacuum controlled switch, but I am not sure what its purpose is yet.

Thanks

Okay. Sounds good. Let us know if the part in the link above is correct as well when you get back in front of it.

Thanks for letting us know.
