Hi foks,

        returned from a 400 mile trip in the 85 camper.  A great trip building up confidence. 

        I did notice an unfamiliar sound and traced it ultimately to my fuel pump.  This is a relatively new pump changed out searching for a problem a couple years ago but not many miles ago. 

I think it gets louder as it is used.  I also notice that it is loud for a moment when turned on then smooths out. 

Is this similar to your fuel pump? 

        I have a couple spares, a new Bosch, and a new aftermarket. I was planning to keep one spare in each van.

What do you folks have for experience with this? 

I hate to change out a perfectly good pump for a second time! But, better safe then sorry. 

Can the used pump be cleaned out and kept long term as a traveling spare?

Your thoughts and experiences. Appreciated.
