Default fuel leak

has any one had a problem with a fuel leak near the injector pump, i already replaced all the lines that go back to the tank. on the passenger side of the injector pump there is a steel line that connects to a rubber line, i changed that rubber line because i thought i saw the leak there. no i suspect that the steel line is leaking, suggestions?

Possible that the banjo bolt gasket is leaking. Try cleaning the suspected area with some brake parts cleaner and see if it gets wet again.

no it is dripping very steady, i suppose that it could be running down the line and hitting the hose clamp

I have a 98 12 valve and I recently found a fuel leak by the fuel filter/block. I believe its on the return line to the tank, it has not effected performance or starting. If anyone has experienced this same issue help me out.
