I usually take the stock cars temperature sending unit and mate it to the LS engine. On the passenger rear head there will be an Allen bolt that goes into the coolant passage. The thread into the head is 12x 1.5 and that is where the 928 coolant temp sensor needs to go. Hopefully you have tagged the original harness for coolant , starter wire and oil pressure.

The oil sending unit is at the back of the LS by the top transmission bolt. The LS 3 ecu doesn’t need this so you can buy an adapter to go from the machine thread in the block to the thread in the 928 sending unit.
As for the fuel lines the first thing you need to determine is what kind of lines to run ( all a/n or push lok or fuel injection rated clamped fuel line). Not sure what you have for this or the regulator. Pictures would be good and help a lot. Not sure how the Porsche lines were connected to these fuel lines in the picture, but almost always there is some sort of barbed fitting that the flexible line bites into. If there isn’t anything but smooth pipe to grab, it’s not going to be good. The ls3 injector rail is 3/8” and I use aeriquip push lok fuel hose with push lok fittings to the regulator. Not sure if the 928 has 8mm fuel lines or 10 mm. At any point I can only see using a good compression fitting on those fuel lines pictured, to get you to a pipe thread and then to a barbed fitting or possibly a/n fittings if you desire.
I would guess you are using the stock fuel pump and filter in the rear?

On my LS1 swap project, I found a VDO A2C59517248S sensor that fits directly into the head at that spare plug, and is supposed to read the same scale as the original 928 sensor does. (This was from HP18Racer's swap documentation thread here.)
As far as fuel goes, I haven't installed it yet, but am planning to run mine like XSChop did (here and here), with a C5 Corvette filter/regulator mounted in the engine bay, and new adapter hoses to connect from the hard lines to the filter, and from the filter to the fuel rail.

For fuel lines and regulator, look at posts #199 thru #203. https://rennlist.com/forums/928-foru...z06-build.html

Thank you all for the information! I have been looking at those posts and am hoping to follow the fuel lines and get more information on it this weekend.

Interesting tips here. There's a 5.3 LM4 (all aluminum) sitting in front of my 928 with pairs of 862 and 317 heads. 2 GT35 turbos are in the rafters too. Was supposed to be for a track 944, but now the little devil on my shoulder is telling me there are 928 plans for it....
