Has anybody got an injected R1 fuel pump/sender assmbly that they've not fitted yet? If so could you measure the resistance across the level sender terminals in both the full and empty positions and let me know the readings?

I know a 450ohm resistor will put the light out but I'm trying to rig it so I can use the low fuel trip reading thats in the dash.

Cheers Chris. I'm trying to use a parallel resistor to get the dash to see what it expects from my Racetech sender unit (with diodes to stop it affecting the Racetech gauge reading). My first attempt has failed and I can't remember what numbers I was working from or where they came from.

I'm not using the R1 pump. That'd be too simple!

So to get the light to come on (and the fuel trip milage to start) I need to get the dash to see the readings it expects. I think I got my calculations wrong with the gizmo I've made so its now down to version 2.
