I am sure I have seen these quoted somewhere but damned if I can find when I need it. I have tried both senders VDO 320.002 and the fuel miser CTS123 [is this equiv to VDO 320.003?] as supplied by Repco, and get no needle movement with the CTS123 and just a smidge of movement with the 320.002 . stat is operating ok and I have 5v at the sender. I have had the gauges checked prior to install, in Balcatta WA. the other gauges in the cluster work fine but this temp one is doing my head in !
