need4speed Posted July 17, 2013 Share Posted July 17, 2013 My inlet manifold is like the one ive attached a picture of. It has got 2 threaded holes in it. According to the parts book 14 is "thermotime switch" and 15 is "Temperature Sensor" The Coolant Temp Sensor from Nige's kit fits into the thermotime switch hole as the other hole is too small. Im confused as id have thought that it would have went into the hole for Temperature Sensor? What should i do with the other hole, just blank it off?

Hybrid_From_Hell Posted July 17, 2013 Share Posted July 17, 2013 Er........ Thats a flapper manifold - the injectors on these are wildly different + best advice is not to use them for Squirting. Hotwire is the way to go ??Nige Quote Link to comment Share on other sites More sharing options...
need4speed Posted July 17, 2013 Author Share Posted July 17, 2013 Nige is it possible that someone retro-fitted hotwire injectors/plenum etc onto this manifold? The reason i ask is that i bought all the stuff as a unit off a 3.9 disco,,,, I think you have pics of my plenum/injectors etc from previous posts. Also, as you can see my injectors have a green band which i thought confirmed they were hotwire type? Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted July 17, 2013 Share Posted July 17, 2013 It's possible the lower half is flapper type, they're the same casting. What will tell you is if there are two tapped holes to bolt the extra air valve on the machined flat bit just to the left of the thermostat. 3.9's all had the hotwire EFI and hence the stepper idle air valve on the back of the plenum, so your plenum & injectors are certainly 3.9 Hotwire type.
