I bought a fuel pressure regulator from you, I installed it because it looked the same, come to find out that the OD is too small for the snap ring and when the fuel pressure built up behind it the part came flying out. Now since I installed it it is my fault for buying the bad part. I guess the 30 orders I just got lucky. There is no customer service so I am out the money. Be sure the price is worth the risk if you buy from rockauto.com.
