Seaflo Brand New 12V DC 35PSI 1.2GPM 4.5LPM 1.7 Amps Electric Self Priming Diaphragm Pump for Boats RVs Campers Vans

Would this pump survive pumping 50/50 RV Antifreeze?

I thought this pump is supposed to shut off if there's no water flowing? As long as it has power, it's on and pumping at all times

Can I use everflo water pump model ef 3000 for popup camper?

Will the pump work if mounted upside down? e.g. under a counter top?
