    So when I bought my 90 blazer the fuel guage was pegged to the right, it was full of fuel but the gentleman said that it didnt work that it stayed pegged to the right. I have had it for a month or so now and it doesnt stay pegged but it doesnt seem to be working quite right either. It will read 3/4 and Ill put in 18 or a little over gallons. The man said he was told it was a ground issue on the guage itself but he also said it stayed pegged full. I was wandering if maybe it is my sending unit that is acting a fool? Does anybody know the answer? If so please help me out Id sure like to know how much fuel Ive got left at any given point. Thanks in advance.

    There is a ground wire from the sender unit to the chassis rail on the left side I think. Check that first before pulling your tank out!
