Thanks for your reply. The problem occurred when i filled up with fuel and noticed it was leaking. Garage tells me it is leaking from seals at top of assembly and whole thing needs replacing which i am a bit dubious about. OK car is 1999 but has only 70000km on the clock! (When only half full, no problem)

There is an access plate above the pump assembly.It is under the rear seat on the same side as the fuel filler.

If it is leaking there it is most probably the hoses or the seal where the pump assembly attaches to the tank.

Fuel pump failure usually means it won't run at all.

If you only noticed the leaking when you filled the tank, perhaps it is the fuel filler neck (or it's connection to the tank) that is leaking. Does it still leak fuel after you have used some of the fuel ? Maybe not a fuel pump issue at all

my 91 was leaking and I took out the passenger side rear seat and opened the access panel , the fuel line was dry rott so I replaced it and also had to tighten the cap that holds the fuel pump assembly on the tank , fixed my leak no more problems.
