CTLR TRIED TO COAX RPTR INTO ACCEPTING A VISUAL BEHIND ACFT Y. RPTR REJECTED REQUEST BECAUSE THEY HAD LTSS. RPTR'S ACFT WAS VECTORED OFF THE FINAL AND RESEQUENCED.

Narrative

RPTR IS PF (COPLT ASSIGNED TO 2 CAPT TRIP). ACFT X ARRIVED IN TERMINAL AREA VIA STAR THEN VECTORED BY APCH CTL TO INTERCEPT RWY 9L LOC APPROX 20-25 MI FROM RWY. CTLR SEEMED TO BE MODERATELY BUSY (POSSIBLY TRAINING). WE WERE GIVEN A SPD REDUCTION FOLLOWED BY A REQUEST TO INCREASE TO BE '#1.' DELAYED CONFIGURING ACFT FOR LNDG AND MAINTAINED 200 KTS APCHING FAF. CTLR VECTORED ACFT Y A B737 TO BASE LEG INSIDE THE FAF AND BEGAN QUESTIONING US IF WE SAW HIM. I REALIZED THIS WASN'T GOING TO WORK BECAUSE THE OTHER ACFT Y WAS HIGH AND WE WERE CLOSING AT A POINT NEAR THE FAF. CREW WAS ALSO UNSURE OF THE TYPE OF ACFT (CONCERNED IT WAS A HVY AIRBUS); SO WE AGREED NOT TO ACCEPT A VISUAL. IT BECAME OBVIOUS STANDARD IFR SEPARATION WOULD NOT EXIST AND WE WERE GOING TO BE COERCED INTO A VISUAL APCH. I QUESTIONED THE CTLR WHAT DISTANCE WE WERE BEHIND THE B737 (ACFT Y). HE STATED 1 1/2 MI; AND THAT WE HAD ACCEPTED A VISUAL APCH. WE REJECTED HIS ASSERTION AND REQUESTED ANOTHER RWY (IE; SIDESTEP TO RWY 9R OR ENTER BASE LEG FOR RWY 13). CTLR STATED COORD COULD NOT BE EFFECTED. WE THEN OFFERED TO S- TURN TO 'MAKE IT WORK.' WE WERE THEN VECTORED OFF THE LOC; RESEQUENCED BEHIND TFC AND LANDED WITHOUT FURTHER INCIDENT. I MADE IT CLR THAT WE WERE NOT GOING TO ACCEPT A VISUAL TO CORRECT HIS BAD PLANNING AND POSSIBLY ENDANGER OUR FLT AND PAX.
