Replaced Whisper King water pump with Revolution 4008 November 01, 2020, 11:59:03 am During our two week trip a month ago we noticed water on the carpet. All the fittings where dry around the pump. I had to unbolt the pump to feel under it. That is when I felt water. It has a leak between the seams. I was able to get a Revolution 4008 from Camping World 20 minutes away from the house for $93.00. The Revolution does seem quieter. My Whisper King has a manufacture date of 6/99 on it. Not bad. Maybe I will take it apart and see if I can replace the seals and keep it as a spare. 2 Likes

If water got into the motor, forget about trying to reseal it.Larry

It should work fine in your 2003. MB. It will require remounting the pump and adjusting the lengths of the hoses. If your original pump is still working, it might be a good idea to change it before it dies, it's easier to change a pump on your schedule instead of when you are on the road, on a Saturday night, far away from a new pump.Larry

The screw holes were closer together but it was easy for me to screw the wood screws in. Other than laying on the floor trying to use two hands at times, it was an easy job.
