75 sovereign par pump replacement

First post from a frazzled first time owner: sooo, I bought my 31 sovereign rear bath in June 2019. Sheís been a trailer park queen for 15 years.( carport covered, jacked off wheels n city water and sewage hard hookups) while being in pretty darn solid shape, water pump system hasnít been used in over a decade. Tank appears to be holding water n par pump does start and make noise. No pressure though. City hookup flows. (No check valve in place) I ordered new connection for rear bumper hookup, but havenít installed it yet. Currently just a copper faucet dangling, but able to close to seal system. I donít get water pulling in pre pump filter. No visible leaks and tightened clamps on old ďradiator ď hoses. ( Yes. Iíll ditch the rubber soon) I was looking to replace pump with more modern, quieter unit. Any suggestions? And from what Iíve read current par has 3 wires to newer 2 wires. How would I wire it correctly? Thanks AS peeps. Pete

I have the shurflo revolution. They claim it doesn't need an accumulator tank, but it performs much better with one than without. The silencing kit (flexible hoses) is also worth adding. With those three parts, I hardly know the pump is on.

The pump has two wires, hot and neutral. Connect the hot to the hot wire from your pump on/off switch, and the neutral to a neutral wire. That's it. The pump has an integrated pressure switch so it knows when to shut off.

Wow ! So cool to see this thing actually works, (forum, not pump yet). I appreciate the reply. Pump and silencer ordered. There is an accumulator tank there. To be honest I didn't know what it was. Thought it was a filter. If it doesn't leak. leave it alone? I'm gonna try it without replacing first. So hoping water system will come to life soon.
Now if I can figure out how to resize pics so they will post..... As I know there will be 100's more questions to come.
Thanks again, Pete
