Replacing water pump on Dad's coach

My Mom and Dad have an '07 Monoco Holiday Rambler. The Shur-Flo pump, Model # 2088-422-444, has been discontinued and superseded with Model # 4008-101-E65. Are there any install tips? I know I should drain the fresh water tank, first. The existing set-up has one-time use crimp clamps. Can I use regular hose clamps for the swap? The one-time use crimp clamps you mention may be connecting the tubing to fittings that have a nut the can unscrew from the pump. However if the screwed on fittings have to be removed by cutting the bands first you can use hose clamps if they are attaching hose. If the tubing is harder grey plastic or pex you will need permanent bands again. My setup unscrewed from the old pump and screwed onto the new pump. Maybe a picture of your dad's pump connections would help.

The existing has a cleanable screen filter attached with a threaded coupling, which I plan to re-use, but the clear cap faces upwards. The clear cap is removable for screen/filter cleaning. I thought a cup/screen-style filter should be oriented downward. Does it matter? No. It is a strainer and not a filter. Orientation doesn't matter for it to work. Clear cup down is best if you can get it turned that way to keep from dripping on the floor when cleaning. Mine is also upside down since that is they way is wound up when it screwed onto the pump inlet. Otherwise just put a couple paper towels under it when unscrewing the clear cup when the screen needs cleaning.

They're full-timing, and Dad just got out of the hospital 8 days ago, so I'll be performing the repair ASAP. He's doing better, and very mechanically inclined (40 years in HVAC), but I can't rely on having his assistance. I plan on picking up the pump at a local RV supply (with a hefty mark-up, but they need it), tomorrow. It's my understanding that the pump will not include any fittings. It sure looks like a gaggle of wires and hoses in the compartment. I assume there's a fuse or something so I can disconnect the 12V to the pump, but I didn't look, nor did I ask my Dad.
Any suggestions or caveats are welcome. It'd be nice not to look like an idiot in front of him or my Mom. I do that, plenty, already.I made the same swap. The red hot wire on the pump has a shielded spade connector already attached so that wire is plug and play. I unplugged the red wire from the new pump and connected the existing one that was on the old pump. The black ground wire on the new pump did not have a plug type connector nor did the old one. The old pump black wire was attached to the trailer wiring with a bell shaped crimped connector. I had plenty length from the existing trailer wire and was lazy and didn't dig for my box of assorted wire connectors since I had the same type crimp connectors (stick both wires in and crimp once) handy so I used one of them. I cut the trailer wire next to the connector on the ground wire, stripped the end and crimped the pump wire to it. There should also be 4 screws through the rubber feet on the pump holding it down. The new pump has the same screw spacing on its rubber feet.
