OES Genuine Expansion Tank Hose for select Land Rover Discovery

Now, the radiator bottom tank has 2 entry points( 2 short tubes),one for fuel cooler return(bottom) one for hose from oil cooler. Ok, On a Landrover discovery 2002 td5 there is a standard, factory fitted, returnflow hose from the oilcooler housing directly to to the bottom tank of the radiator r/hand side.

  This merely involved disconnecting both electrical plugs (already done for the new pump check), clamping the black braided hose from the reservoir and disconnecting it from the aft side of the pump, undoing the banjo bolt connecting the...   This is done by opening the accumulator’s bleed nipple and repeatedly running the pump (by switching ignition on) for a few seconds at a time – this allows any bubles to collect at the top of the accumulator before being pumped out, rather than... The ruber feet of the new pump were already ruined – the rubber can detatch from the steel plates if force is applied to the rubber or opposite stud when trying to undo seized nuts, but the mountings for the original pump were in mint condition...   Following that, with the pressure bleeder still attached, I cracked the banjo bolt on the outflow hose to try to bleed that part of the housing to try to purge the high spots of the pump.   Obviously, this accumulator needs to be charged quickly to a specific pressure, so the pump has a pressure sensing switch which is connected to the ECU, telling the ECU not only whether the system is up to operating pressure, but enabling it to...   Finally, the accumulator was repeatedly bled to clear the air from the pressurised hose.   I sourced a second hand pump, even though I dislike using second hand spares on such critical systems, as new pumps cost approximately £800.   Once fitted, the pump was bled using a pressure bleeder (EziBleed) and the nipple on the pump itself.
