Procedure; Aircraft
Got to the gate and no plane was there.  I Called Maintenance (Mx) because there were numerous write ups on center tank pumps in history.  MX said the aircraft had been at the hangar for 4 days working on fuel pump problem.  After jet arrived at the gate; Mx worked on Equip Cooling for 1 1/2 hours.  Unable to fix; they deferred it in STBY.  Weather was stormy when we took off.  As soon as we got airborne; we got multiple failures including FWD EQUIP COOLING and R CENTER FUEL PUMP low pressure.  Soon after we got a EQUIPMENT OHEAT with an associated loss of both Wx radars and both artificial horizons being degraded.  We asked departure control to keep us out of the weather and to stop our climb.  We ran the check lists for the over heat and asked center to keep us away from the weather.  Since we took off in Standby mode; we ran checklist and went to ORIDE MODE. We then ran fuel pump low pressure check list and turned the pump off.  We called Dispatch and he gave us a patch to MX to see if there was anything else we could do.  We decided to return due to multiple failures.  During this time we got back both artificial horizons; both radars; and the EQUIP OHEAT ECAIS went out.  Still felt very uncomfortable with the whole situation and went with our initial decision to return.  We dumped about 19;000 pounds; landed about 15;000 overweight.  We asked for the longest runway and made an uneventful landing.  We did not touch brakes until 80 knots.  We got into another jet and got airborne 11 minutes before [the IRO] went illegal.
The aircraft has had a history of the 2 systems that failed right after rotate: Center R Fuel Pump Press and FWD EQPT OVHT. Shortly after the FWD EQPT OVHT EICAS both pilots began getting degraded NAV Displays to include loss of WX Radar Displays and loss or degraded ADI displays. We ran the QRH Checklist for both items and restored our degraded NAV Displays after running the OVHT Checklist. We asked for radar vectors while we sorted out our situation; eventually declaring an emergency due to dumping fuel and our imminent overweight landing. NOTE: The FWD EQPT COOLING system was deferred prior to this takeoff with the switch in STBY.
B767 flight crew reports being dispatched in an aircraft with a history of fuel pump problems and the FWD EQUIP COOLING deferred and set to standby. As soon as the aircraft lifts off; EICAS messages for FWD EQUIP COOLING and R CENTER FUEL PUMP low pressure are displayed. The pump is turned off and the FWD EQUIP COOLING is set to OVERRIDE but the crew elects to return to the departure airport.
