i have noticed that there is a perished hose which connects on to the left hand side of the inlet manifold. it also looks like it has an inline filter of some kind and it runs underneath the inlet manifold. i need to drive from devon to gatwick airport on monday so i wont be able to get a replacement hose in time. what is the hose's purpose and does it hold much presure? Would it be ok to carry out a tempory repair using insulation tape and cable ties?
