    Re: Dodgy wiring ...

    Only mod. I plan to do shortly is to fit an inertia switch (probably ex-Peugeot) to the SU fuel pump wire for safety's sake.

    That is when I change the yellow wire to the correct white.
    [and just found the earth wire from the wiper instead of being black has been spliced [by a PO] to light purple wire ...

        Excellent, I believed that I was having a vaporizing problem with the mech pump on my1800TC so I fitted a SU I had kicking around by the wiper motor. It does vapourize in hot slow traffic so maybe a facet would be good and the SU can go back in my Landrover spares box.

            As I have said before there appears to be a strong correlation between modern Ethanol fuels and fuel system problems.
            Certainly, pump and seal materials from 30 years ago would not have been required to be compatible, and I woukd be wary of chinesium products.

              Even more - and much cheaper - in my local scrapyard.
              They even tried to give me a switch as it was not worth charging for ...

              Good point from Steve G in #20 about ethanol content damaging lots of materials - that includes NOS mechanical pump kits/diaphragms etc. (thank the 'Greenies' for promoting this particular ill-checked change ...).

              Ref pressure and SUs - they seem to be quite sensitive - which may be why the American PO of my HRG fitted Grose valves to the twin SUs.
