This is important
On my 07 H-36 the the gauge stop working and without taking out the sensor there is a ohms reading you take for testing either in your manual or wema web site and my reading said it was good and not defective,I took it out and found the newer stainless tube sensor all clogged up and did clean it but still very in accurate and really not give good reading until it was full and not real warning.
I will be changing to outside tape on sensors.

Ok,,, the wema sensors screw in with 4 machine screws.
As the tank is not thick enough to take a thread, there is a threaded retainer collar inside the tank.
This is a little tricky.
There is nothing holding the retaining collar in place except the 4 screws from the top.
If you remove all 4 screws, the collar will go "plop" into the bottom of your tank.
Not good.
Here is what you need to do.
You need threaded rods about 3" long the same thread as the existing machine screws.
Now, remove 2 of the screws, and thread the rod through the sensor holes into the retaining collar with about 20 turns.
Put temporary nuts on the exposed upper ends of the studs.
Now, remove the other 2 screws.
Carefully lift up the sensor. You may have to cut some sealant to do this.
Once the sensor is 1/2" above the tank surface, carefully put two cable ties around each of the studs so that you are "capturing" it.
Now, remove the nuts from the top, and you can pull the sensor straight up.
Install in reverse order.
Use a small amount of silicone to seal the sensor when you replace it.
Do not use 4200 or 5200!!
