Well good afternoon. I have been searching the web as well as this site obviously and have found a few old postings about replacing the sending unit that have assisted greatly. Problem is, that I'm about to re-install the gas tank and the sending unit wiring harness that feeds up into the trunk (connects to a splice plug for the license plate light) is all good however, the hole it routes up through was sealed up with what looks like old bonding of some sort. What is the proper way to seal that plug area and secure the wiring harness? Hope that makes sense and I can post pics if necessary. Thanks for the assist and have a great week.
