how to build a hydraulic transfer tank ?
 

I sometimes find I'm in need of filling something with various oils/gear oils/hydraulic fluid that are not readily done with a funnel. The latest issue is I'm going to do a filter/gear oil change on my 317 John Deere hydrostatic transmission. The fill tube for the hydro unit is in a very tight spot. So I would like to make a tank maybe 2 to 2.5 gallons that I can fill with fluid. I'm thinking of using an old metal gas can that I have. The metal can has two threaded caps. One is quite large the opening is almost big enough to put your hand in. The cap has a rubber vent button you push down to increase fuel flow. I would replace that rubber button with a air hose quick connect. The other smaller cap has a rubber spout. I would replace that with some type of fitting that would allow hose to be inside the tank with a hose barb on the outside. On that hose barb would be hose of whatever length needed. So fill up the tank, add air pressure from my compressor and the fluid should come out the hose correct ? I would think 5-10 pounds of pressure would be enough. Could even install a ball valve to help control output. So what do you guys think will this work ? Does something like this exist over the counter to purchase ?

Google oil safe containers. I have used these and they work real well.

I use one of these in a gallon jug

Or one of these in a 5 gallon bucket

Can't use a funnel with a long tubing? Tubing can loop around obstacles, keep funnel high.

Or I've used one of these before, again with tubing on spout: Oil Suction Gun - Save on this Suction Gun at Harbor Freight

Yes a funnel could be used with tubing but I have the compressor so why not make something ?

I've had a JD 316 and a 318...........Long tube and funnel work well.

Pete has it, cheap, and safe. Don't pressurize an old gas can or something like that. If 10 psi in a five gallon can ruptures, you'll get hurt and have a REAL mess to clean up.

Pressurizing a can that is not designed a pressure vessel is not a good idea, even 10 psi can be very dangerous.

Get a hand pump.

Boom. Nine bucks. Done.

Yeah I was thinking about a garden sprayer also. Probably the best way to go.
