Well still new here. Just have not been on here in a while. So got a used 30 gal air compressor. It does not have the original pump and motor. So I think the original configuration had 5hp combo pump/motor. So what can I use to to get rebuild it? Just light duty use, should a 3hp pump with separate motor be ok?

A true 5hp compressor will have usually come with a 220-volt plug.
FWIW, a neighbor gave me an old big box store IR 5hp compressor, saying, "It won't pull up to speed; it had a funny plug on the end so I had to change it. Here's the old cord and plug." Of course, it was a 230-volt motor and he was trying to run it on 115-volt. Reinstalling the 230-volt cord and plug and it ran perfectly.

some pics would help, but if you just have a bare tank with nothing on it, you can be fairly open to what you put on it. however, the costs can add up quickly if you start buying pieces . if you're planning on buying new parts , save your cash & buy an assembled compressor . are you sure the tank is good?
keep us updated for sure on your build .

I did a similar project once, got a used 5hp motor from a motor shop for around $50 and a Harbor Freight compressor, https://www.harborfreight.com/145-psi-5-hp-twin-cylinder-air-compressor-pump-67698.html . Did the whole job for around $300. Wasn't bad for a 17 CFM compressor but you will need a 240v power supply. This compressor runs daily at one of my shops and hasn't had any problems in about 10 years.
So thought I got a good deal, but I got ripped. Anyway it's definitely a homemade setup. No shut off switch, plug in and it runs. Have to fix a hose leak. So should I fix it or give it away?
Only has a 1/3 hp motor and air pump from a sprayer? Any advice would be appreciated.

How long does it take to fill? Lol
A nail gun uses very little air, a tiny 2 gallon hot dog will work fine for that. A air ratchet takes more air, a fair amount actually, but you typically don't run it very long, a 3/4 or 1 HP will run and air ratchet. An air sander is an air hog. They will **** up 10 to 15 CFM, plus they are typically run for some time, not short bursts. You will need a 220 volt unit, at least 3 HP 10+ CFM out put. A 5 HP two stage will run an air sander all day, but they are not cheap.
I would seriously think about the tools you want and need to use, and how often. There are many 60 galon single stage units that claim crazy HP numbers with a 15 amp motor. 15 amps on 220 volts will net you about 3 HP and 11 CFM It will run pretty much any thing a weekend warrior will throw at it ecept the air sander will probably bit more than it will keep up with on long runs. Perhaps an electric sander will work for you for the times you need it.
you probably had a good tank & that was it. you probably made a good choice by getting rid of it
