Is it necessary? It was falling apart on my old pump, and its replacement just fitted was the same, so it was ditched!

The foam often gets removed when it gets soaked. I have never seen a problem due to it being missing in the UK.

Did it get fitted to later cars? No sign of our 05-plate ever having had it.

Mine doesn't have the foam either.

The foam is known for taking in water and basically holding the water against the pump.

I removed mine and put grease around all the wires and plugs.
