FUEL PUMP KIT, BOSCH TYPE, TR5-TR6, PI

This kit is fitted to replace the original Lucas pump which had a definite tendency to heat up and then burn out.
This Bosh pump is more reliable than the Lucas but unfortunately it is also noisier...
ATTENTION, it is absolutely necessary to change the pressure regulator (PRV = Pressure Relief Valve) for correct operation.
