The level sender on my IDI (2 wire) (midship tank) is finally degrading to the point where I want to replace the unit. This would be straighforward, if the connector was not disintegrated and (glued?) in by a PO.
I cant find a replacement pigtail for that thing anywhere, but the 4-wire deals that will also run a fuel pump are plentiful.
I figure that I can swap in a 4-wire pickup/sender unit and only use the sender wire and ground with a new pigtail. A question I don't have the answer for is whether the diesel and gas units use different ohm ranges and thus this wouldn't work. I'm pretty sure the tanks are the same (19 gal).
Also open to any other suggestions. It looks like an 87 mustang pigtail would work for the 2 wire, but trying that does not seem as good of an option as using connectors that I know will work.
