I have a 94 CNG Dodge Caravan and it needs a new part but I cannot find it. The part number is 4682947, I believe it is listed as a Fuel Injection Pressure Regulator or some high pressure valve. Any good places to check?

 

Try rock auto or ebay.

 

What is your source for the part number? You might start with a diagram on a parts site because a search for your part number on google brings up your post on this forum and nothing else to do with Caravans.

According to this, the part is in the cooling system for a "Natural gas S Body"
