I've been around Volvo 740's for nearly 20 years and I've never seen this. The main fuel pump in a '90 740 Turbo Sedan I service is leaking from around the front face, near where the tower for the electrical connector is located. The fuel system is Bosch LH injection. The gas runs to the rear of the pump, drips on the frame and to the ground. The car seems to run fine and the pump sounds normal (no cavitation). It leaks about one drop every two or three seconds.

I'll have to replace the pump and filter.

Has anyone else seen this?
