How many fuel pumps has 1991 Volvo 740 wagon?

On 1990-93 models, Volvo uses three types of fuel systems - Bosch LH-Jetronic, Bendix Regina, and Bosch Motronic.

"[Bendix ] Regina and post-1994 cars have only one pump". (my info source is http://www.brickboard.com/FAQ/700-900/FuelSystem.htm#FuelPumpandFIRelayDiagnosticTests)

In the Regina case, that single pump is located in the fuel tank.
