Faulty Fuel Pump for a 1993 Volvo 850 GLT....

[Quondo]

Does anyone know if there are any reliable web links on where to buy a used or new fuel pump? In addition, any web link instructions on how to install your own fuel pump on a 1993 Volvo 850 GLT? I am pretty sure this has been the source of my stalling problems (as I have changed all spark plugs and wires, cleaned my MAF, put in a new fuel pump relay and have put in a new ignition coil, and would like to save some big money by doing the fuel pump job myself. Thank you for any replies to my question.
