The S3 & S5 senders are the same except for the fitment on the head.
Both are made from 316 stainless steel and both are suitable for use in Petrol (Gasoline), Diesel, Water, Grey Water & Black Water.
For fuel & water senders we recommend a sender about 1" - 2" (25 - 50mm) shorter than the tank. For holding tanks (black water) the sender should be no longer than 75% of the overall length of the tank.
With so many variables; length, port size/thread, vent, resistance, filter etc., there are literally hundreds of different versions of these senders so it's always best to give us a call and we can make sure that we supply you with the correct unit for your vehicle.
If you have an existing sender the identification number printed on top plate will be very helpful in identifying a replacement.
For new applications please give us a call to discuss your requirements.
To supply a replacement fuel or water sender we just need to know:
What type of sender do you have?
What resistance is it?
How long is it?
What type of tank is it being fitted into?
What is the Wema product code?
