Just replaced the fuel injector pump. Now the line from the fuel/water filter to the injetor pump is leaking. I can see with a mirror it's leaking from the fitting at the pump. When I changed the injector pump, I noticed black plastic type material falling out of the compression fitting. Any ideas on how to get it to stop leaking or where to get a new line? I've found the lines from the pump to each injector on-line but not the line from the filter to the pump. Thanks
