The branding on the bottom has rubbed off so i cant quite tell but it looks like a 380. It has ribbed hosing. Unfortunately, the writing has worn off the pump as well. All i could make out was C-Fab 1.5HP. Clean filter pressure is just over 10PSI.

Thanks for the advice, I really appreciate it. Think i'll take a stab at it this weekend and if the polaris slows, I'll just have to add the booseter or put it back the way i had it.

Again, Thanks for taking the time to give me some advice.
