fuel gauge off
I replaced my fuel sending unit and my fuel gauge, the old one would "tick" back and fourth going down the road and someone in the past knocked out the filler neck to run leaded fuel I suppose. now the problem is when I have 5 or 6 gallons left in my 77 it reads that I only have 1/8th of a tank left. is there any way to calibrate the gauge, the bladder looked like new inside the tank. and when I filled it after I replaced the sending unit it took right at 16 gallons.

Did you check the sending unit before you installed it??? If you did...and it went to empty, full, 1/2, 1/4, and 3/4 by manually moving the float...then It could be the actual float material is too heavy and not floating on top of the fuel I have run into that problem before and I re-used the factory float material on the new sending unit. I had both of them off and weighed them on my paint scale...which is very accurate to a 1/10th of a gram and could see that the new material was almost 1 and a half times heavier. So 7 grams for the original...the new one was like 11 grams.
I know the scale is 0 to 90 ohms is what the sending unit should be sending to the gauge.

In the future...for what it is worth....here is a "GOLDEN RULE" I follow.
I call it the "95% rule":
95% of the time...95% of the companies reproducing parts reproduce them to 95% of what they should be. AND...it takes 95% of my time to finish out that last 5% and make it right.
With all the "bean-counters" out there...sticking their noses in what can be done to reduce costs and increase profits when parts are being made...or grouping different parts into one category.....and the FACT that "they" have no knowledge on what is going on to "us" guys and gals trying to use/install these parts. "They" figure that if the part is bad/wrong or incorrect....oh well...the chances that you will pitch a fit and complain USUALLY falls on deaf ears and they will take that chance. I encounter this more times in a week than you can count. And trying to find the "right stuff" is often times exhausting.
