have VDO top tank mount sender with racetech electrical guage.. Swapped the old westfield led type for the racetech one.. But the guage is reading backwards! Getting fuller.. Lol any ideas how to rectify it?
Praise the lord it’s a miracle!!
Swap the connections around?

Leave it as is and sell all the extra fuel to us Locosters!!! You could make a fortune there!!!! 
as you look at the back of the gauge the 12v supply should go in the left of the three connections on the bottom, the earth in the middle and the sender wire in the right, the twi connections on the top are for the light.
anyone got a syphon tube?? you keep him talking & i,ll sort the fuel level out
as victor meldrew would say....
i doooonnn,ttt believe it !
i,ve just realised the car in question lives in same town as me ,
right where,s that tube???
honestly same town, how spooky

On my sender in the tank you can swap which side of the sender the arm with the float comes out of thus altering the sweep area depending on the tank level
Had the same problem with my Greengauges gauge and sender . Turned out that the assembly diagram on their website was incorrect. Turning the resistor pack over sorted the problem out. I don't think I'm the only person to have had this ?
I had an incompatible gauge and sender too. In the end, like Rusty, I turned the resistor over in the sender and bent the arm a bit and that solved
it.
Its because there's 2 standards. One that reads 0 - xx Ohms and another that starts at 50 odd Ohms and stops at around 180 Ohms I think. Anyway,
you get the theory even if the numbers aren's right.
i have turned the small removable arm over to cure it - but its not clibrated to the guage - well nearly right - when the sender sweep is all the way
to empty the guage ont go below 1/4 full - presume the range is out - any ideas how to rectify that? new sender of course to match but then the age
old worry - will it fit the hole in the tank?
lol - probs are never easy.. bit by bit they are chipped away at..
