Hydraulic Questions

I am pulling a wet kit on my truck. I have the pump and winch mounted but I need a Hydraulic tank, and some advice on the volume of the tank.
I am thinking 24x24x18 tank mounted behind the fuel tank.
I don't know the gallon volume of this size tank and if it will be what I need.
I am powering a hydraulic winch.
I also need input on the placement of the hydraulic filter. Suction or Return?
Any ideas on where to find a tank?

First, you should have the tank be 3-4 times the pump volume, IE: if the pump is 3 GPM then have a 9-12 gallon tank. You should be able to buy hydraulic tanks from Northern tool, they have a website. Be sure to get a tank with a filler breather port. Also filtration should be an inlet pump strainer, large enough and be inside the tank. There should be a return spin on filter which should be a 10 micron rating. The inlet strainer only needs to be a 25 micron rating. BTW....What is a wet kit?
What kind of control valve are you using? be sure to have an adjustable relief valve too.
 
What type of truck and what will you be using the hyds for. If you look around and find a truck salvage yard they should have a good number of hyd tanks. I know when I put a wet kit on my truck, turned it into a dump truck I used a tank from a salvaged dump truck I haul in

If its a round tank you can get the volume by Pi times the radius squared times the length of the tank. Divide this figure by 231 cu in to get gallons. If its a square or rectangle its l x w x h in inches divided by 231 to get gallons. 231 cu in to a gallon. Looks like the suggestions you have received are pretty close.
 
You might want to try surpluscenter.com for a hyd. tank. Buying new is better if you are installing other new components, takes the mystery out of troubleshooting hyd components(which used part is the dirtiest?).
 
At this hour I'm not going to figure the volume of that tank, but I'd ballpark it at close to 30 gallons full. It's bigger than my tank for the wetline, and that holds 4 can no problem. Unless you're going to run this thing for hours at a time, I'd say it will be fine. I'm assuming that you're using the standard 1 section pump for this... which is about 25 gpm. Generally, or at least in theory you would size the resevoir to be 3 times the pumps capacity per minute, but on intermittent applications like this it's not needed. A boom truck or log truck with a 2 section pump would be a different story.

Other than that, I'd suggest you go with a 2" suction for the bit more it will cost, and a 1" return filter. Plumb both to the bottom of the tank, and install ball valves on both the suction and return lines so you can disconnect without draining if you ever need to remove the pump. Forget about the suction strainer. It'll create a restriction you don't really need on a suction run like that....
Just don't undersize or compromise the suction. I already bought that badge of honor. It only cost me a pump.... 2 seconds more and it would have cost a PTO too.
Small saddle tanks make great hydraulic tanks if you're handy with welding aluminum. Otherwise, the surplus centers or a truck parts outfit.... or junkyard. I made my tank, but it was made for a spot at the time, and a commercial tank wouldn't fit.

That tank would be 44.88 gallons total. Don't know your pump volume. Surplus center would have a tank.
Put the filter on the return
