    my old 2.5l 40l air compressor packed it in a few years ago, just doesnt pump or turn on, and i replaced it with a 20l 2.0hp model, not as good, but can i rip the tank off the air compressor, and plumb it into the new one, to give extra air storage? i know it has two nitto connections on the output, i was thinking one in, one out, remove all the other stuff from it with an angle grinder.

    any ideas?

    Internal corrosion is the concern. Use a lighted probe to examine it.

    Yes, you can. The hook-up could be as simple as just adding a "T" in your existing line, and connecting to the output of the old tank (with the regulator on the old tank turned all the way open)

    You could do a much neater/professional install -- which would be nice... but it will work fine either way.

    You dont want the feed between the two tanks to go through a regulator, you want them both at the same pressure for maximum storage.

    What sort of connector is there between the pump and the tank?

    What was the pressure rating of the old compressor? How about the new one? My biggest worry would be if the new compressor had a higher pressure output then the old tank was rated for.

    Beyond that there are several ways it could be plumbed. After the regulator would give a big resivior of air at the regulated pressure. Before the regulator would give a bigger resivior of air reducing the cycling of the compressor (fewer cycles, longer run time, longer off time, same overall number of hours).

    the older one was 2.5hp, the new one is only 2, so i assume it would be right..

    HP has nothing to do with pressure. I know of 3 different 5 HP compressors. Outputs range from 125 PSI, 175 PSI and 3,000 PSI. Bu the flow ratings are very different. The 3,000 PSI is very slow.

    Just connect the two tanks with a piece of air hose. The pressures will take care of themselves.

    If the new compressor tank has a plug in it, remove the plug and use a short length of hose to connect the 2 tanks. The compressor discharge will have a check valve where it feeds into the tank, remove this on the old tank and connect your hose there. This will allow you to use the existing regulator and hose connections on the new compressor and the old tank will add volume. Make sure you drain both tanks often to prevent corrosion.

    I do this... just remember if you put a shut-off valve on the line going to the second tank (which can be useful) then said second tank should have its own pressure relief valve.

    Being able to not fill the second tank is handy when you're in a hurry for pressure. My "3hp" (110V 15A :rofl) compressor can take 15 minutes to fill both tanks. Annoying if you just want pump out a few nails or something.

    Post pics of your old and new compressors, and we can give you some options.

    Come on dude, where are your priorities? You'll have the rest of your life to deal with that child... we need pics of your air compressors! :rofl

    Congrats on the addition to your family!:clap
