Re: Gas Guage Prob's
my 78 Jimmy bounced
when I changed from idiots to tach and cluster
i had to add a seperate ground for the fuel gauge ground
it stopped
my 79
I was worried changing to a spectra unit this summer it would bounce
nope
if it's working right, grounding the sender wire is E,off is over F
I'd check the tank ground for sure
