Thanks for the info!!!!!That is an awesome post. Very clear pictures and instructions. My sending unit works as far as it sending a signal to the guage. The problem with it is one of the ports is broken off the top where one of the lines goes in. I did however find one relatively inexpensive at a salvage yard. So I think Im going to replace it this time but I will definitly keep this info on hand if I have any other challenges with it. Thanks again
