9n3 TDI Fuel Level Sensor

Post by Dubaholic69 »

Hey Guys,

I just want some advice please, I've bought a new fuel level sensor with the float and I want to replace the current faulty one on my in-tank fuel pump.
I saw when I removed it before to have a look, there are 2 blue wires connected to the sensor but I didn't check if there are some kind of sealant on the contact points, so I want to know if anyway has done this before and if yes then can I just solder the wires onto the new sensor and it will be good or do I need some sealant?

The new sensor's PC board doesn't look like it has any sealant on (otherwise it won't get a reading for the fuel gauge from the contact points) so that is why I think everything will be fine as the wires is only there to provide a reading?

Thanks in advance.

no sealant. and silicone sealer for instance is dissolved by petrol so don't want that near the inside of a tank.

I bought it from VW unfortunately as Goldwagen didn't have, price was R1365.

Unfortunately I already replaced it this morning without taking photos, my apologies. It was easy though, the wires clip in so no need to solder anything.
