Well i removed the bed and the sending unit from my 87 to see what was wrong and the thing was all normal. 3 Ohms at empty and 94 Ohms at full. I did find that the sending unit and pump are only recieving about 6Vdc input and i though this could be the cause of my faulty fuel gauge readings. What do you guys think. I know the gauge works fine because when the sender is removed from the loop the gauge reads full but when it is plugged in the gauge will never read above 3/8 tankwihte the sender at full??? Any suggestions.
