I am from the SRT8 forum. I bought this gauge, then realized my fuel rails don't have a valve. It's for the SRT4. My loss is your gain. New in dealer box. Never installed. Mopar dealer carbon fiber fuel pressure gauge part# MOPP4510415. This gauge sells for 250$. Trying to get some money back, I want 100$ pick up, 105$ to ship it. If you are interested send me your email I will send you pics. Thanks for looking.
