I'd be more worried about the position of your fuel filter. It has been argued in the past that the best place for the filter is before the pump, not after. I've got mine above my gearbox to avoid it being anywhere near a source of heat.

IIRC those came with more complicated US-spec emissions controls, perhaps that is the remains of such a system?
