NOTE 1: This kit must have a good electrical supply capable of passing 13 amps. The original car wiring is not adequate, as the Lucas pump only requires 3.5 amps. We can supply a relay kit part number RTR4017K. See below.
NOTE 2: TR5 and early TR6 cars did not have an anti-surge reservoir in the petrol tank. Cars fitted with this type of tank will experience fuel starvation on tight left hand corners with less than a quarter of a tank of fuel. Our replacement tank fitted with the correct anti surge reservoir, part number 312359AL or 312359XALK should be fitted to remove this annoying symptom. See Fuel Tank Section.
NOTE 3: Fitting RTR4050XK should take about three hours.
NOTE 4: When fitting kit RTR4050XK outside the bodywork, shield RTR7259 may be useful.
NOTE 5: Also consider hose RTR4048 to the PRV which helps to reduce resonance. Resonance is when the Pressure Relief Valve (PRV) fluctuates at a resonant frequency with the pulses generated by the fuel pump and an unpleasant droning noise is produced. This phenomenon is unlikely to occur with the original Lucas pump but is very likely when a Bosch pump is fitted. A longer soft hose RTR4048 from the pump to the PRV usually cures this (a stainless Steel braded hose will make it worse) but brings with it another bit of bad news. As modern fuels are much more volatile than older fuels they can permeate through rubber hose and create an unpleasant smell in the boot. If this is unacceptable there is a definitive solution to all this. We have a modern PRV available RTR4456K which works on a different principle to the original type and does not resonate. The good news is that a Teflon lined Stainless Steel braided hose 215642SS can be used from the pump to the PRV which will greatly reduce petrol smells in the boot.
