Jaguar fuel pump problems?

Fuel pump is new but still fuel pressure is low.
One of the customer visiting our garage got the after market fuel pump replaced on his jaguar but still had this problem.
We got the another pump connected to the fuel line and all got worked.May be in your case its faulty fuel pump,that is causing the problem.Get the fuel pressure tested.It should be between 40 psi to 45 psi.

I suggest you to go through this list of help links.
