Aftermarket fuel gauge

Make sure your gage is for mopars, as far as ohms go. It should be 90 to 10 ohms,or real close to that. GM gages will not work.
Is your tank grounded, either thru the metal fuel line at the tank, or like I did. I put an extra ground wire from my tank to the frame.
Otherwise, start checking all your grounds, at the dash, tank, and in-between.
The gage has to be grounded also. It should be marked on the back, with a separate ground wire. Check the whole length of the blue wire, make sure its not pinched, somewhere. Dave
 
Okay i have a problem i hooked the guage to power when i turn the ignition on the guage goes right to full when i hooked the sending unit wire up at the sill plate dark blue wire it stays the same .any help please
If it shows full-over full pinned out, that should be an open circuit. Check the ground to the sending unit first. It should be appropriate 10 ohms full and 73 ohms empty.
