Now you've got me thinking.
I've got low pressure rubber hose running from back to front and on the return from the swirl pot to the tank. I've got high pressure hose between the swirl pot, filter, pump, fuel rail and back to the swirl pot.
Having seen this thread I checked the IVA manual.
Nothing, or at least I couldn't see it or missed it.
Now common sense says use HP hose in the HP part of the fuel system but I can't see anywhere in the IVA Manual that refers to it and therefore, what the VOSA testers will be checking against.
Changing all my fuel lines to HP hose will give me peace of mind but do I
need to spend £30 to £40 to replace it all and has anyone seen where the requirement is documented.
