Fuel Gauge

[oldcarstulsa]

my guage does the same thing, using 02 cluster, but 83 sending unit, it is because the newer tanks use a 33 -240 ohm sending unit, older one uses a 0-90 ohms, your sending unit is prob. a 0-90 ohms

What are you guys doing with the fuel gauge? I have a '98 1500, and the old PCM had a fuel gauge output wire on it, but the new PCM ('02 1500) transfers the fuel guage signal across the Class 2 Serial Data. Is there anywhere I can run the fuel gauge wire to so it can pickup the signal for fuel level?

well thats a scary thought wonder if ill have the same problem with my 5.3 swap. if i have nelson redo the wiring harness i hope that should take care of it.
