Fuel Rail Leak

There was some residual fuel on the rail, not wet , but you could tell some fuel had seeped out. Also around the injector bolts. I don't want to exagerate, it wasn't alot but it just worried me. Is this normal somewhat? Could some tightening down help this?

There is a gasket at the pressure relief valve that tends to leak if you run a pressure box. It only costs like $2.00 from Dodge. I had one go bad and the wind from the fan blew it all over so it looked like several leaks. It's very simple to change. I'd suggest cleaning it all off pretty good and then fire it up to see where the actual leak is.....

My fuel pressure sensor went bad and was leaking. It took a while to pinpoint because of all the fuel fittings in that area, let us know.
