Access from above master bed for my 2001 American Coach Tradition. Actually climbed through opening and determined I would have a heckuva time reaching and some things I could not see, so "Cummins Pacific" in Inland Empire replaced mine. Steamed engine and checked for any other items maybe needing to be addressed. No additional items and I had just replaced fuel filter so approximately $795 later, fixed and I left it there overnight. Best money I spent from what I could tell. And yes they used to sell just a gasket, but I could not locate one and just bit the bullet. I do most maintenance and repairs that just come up, but glad I passed on this one! By the way, the lower cost for my motorhome was due to the easy access for the repair technician. Guess he was thinner with longer arms than me:) Good luck!
Happened in my driveway too thank goodness. And as to your:
"Before I get into this, wondering if anyone else here may have replaced yours by yourself? Any tips, advice or anything I should be aware of when removing the old and installing the new pump?"
Have it installed unless you are certain you can reach and don't mind not being able to see everything you will need to work on!
