2 in 21 months ! so im attempting to fit the fronty one i have . right the question is this - my dash gauge has been goosed since i got the car , now this fronty rad is requiring some artfull bodging on the pipework so i want to fit a temp gauge in the car , but i aint got one so was wondering if i could use a fuel gauge instead ? both electric and run on the resistance of the circuit, just different gauge fronts im thinking ?(hoping) 
, doesnt need to be an accurate temp , just an indication of where the temp is , so if any of these pipes either split, weep or hook up in the alty belt i'll see an increase ! 
so yes your plan should work,,,,,I should say my mate was colour blind
. just got a proper temp gauge . i should have done this job when i put the engine in like , but feel a bit happyer now ive got the old finger out and done it , now for leaks tho i need another mot in november ! soon to be used for towing the boat im doing up (taken 14 months so far ) which was the reason for owning a 4x4 in the first place . im hoping to make the record attempt in september too ....
