This adapter will take any fuel sending unit and allow you to adapt the signal to any gauge (assuming they both use a linear ohm range)
So if you have a Mk1 rabbit gauge cluster and you’ve installed a mk4 style pump housing for your FSI swap, you can keep your stock gauge cluster working with this unit.
I have used on foreign and domestic cars with aftermarket gauges, factory gauges, it doesn’t matter. As long as your sending unit uses a linear ohm range (ie 0-30 ohms or 30-270ohms or anything in between) this will work for you.
It’s programmable so you can build yourself in a reserve if you set the “empty” level up alittle bit. Instructions for installation are included in the box.
Requires power and ground and then of course your signal in:out.
