Hose rubber from petrol pump to Pressure Relief Valve (PRV) TR6 where the PRV is at the left hand side of the petrol tank (many TR5's will have been converted to this arrangement).
Consider using 215642SS which is a Stainless Steel braided hose, and is therefore much harder wearing than the original rubber hose. Be aware that if this hose 215642 is used in conjunction with a Bosch pump kit such as our RTR4050K, resonance is likely to occur and will certainly occur if 215642SS is used. However there is a solution. See note 1 below.
NOTE 1: 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.
