How many ohms is a GM sending unit?
Tanks offers a wide range of senders for your GM product. Standard 0-30 ohm for pre 1964 and 0-90 ohm for your post 1964 build.
if anyone needs two 90 ohm gages i have them.
looks like much more research, found:
99-02 was 250full, 40empty
03+ is 40full, 250empty
still looking to confirm the vans.
dug wire out and after putting 50$ into the 53 which is a 2005 GMC 3500 Express, reads 220ohms
