Review: It goes between the compressor and the regulator, and it works. - A week or so ago I picked up the better airbrush kit at Harbor Freight. While I eventually got it dialed in to a fairly steady pressure, I realized I needed a set up with a tank. Very seriously considered taking it back, paying the restock fee, and getting something else. Did a quick search and found this. It works a treat! I get consistent pressure at the brush even with long sprays. It's true, there are no instructions, but there is a video out there of someone assembling part of it. I'll give a few pointers here, but these will be specific to the Avanti compressor from Harbor Freight. 1.) Pick up some new O rings, 1/4 in ID 3/8 in OD. The rings that come with the kit aren't great and I over tightened the first time I tried and destroyed two of them. 2.) Pick up a 1/4in by 1.5 in Nipple, I'm adding a link here, but I got mine cheaper at the local hardware store. There are other options, but this is what they had and it works. https://www.desertcart.com/EDGE-INDUSTRIAL-Brass-Nipple-Length/dp/B07DCF9J2J/ref=sr_1_4?crid=346J2P7P6OVIU&keywords=1%2F4%2Bby%2B1.5%2Bnipple&qid=1652562653&sprefix=1%2F4%2Bby%2B1.5%2Bnipple%2Caps%2C93&sr=8-4&th=1 3.) The cutoff sensor on the Avanti is the same as the one that comes in the kit (3kg on, 4kg off), so no need to mess with it. 4.) You'll need either thin open end wrenches of appropriate sizes (12 mm and 14 mm) and an adjustable (crescent) wrench, or you can get away with the crescent by itself. To assemble, 0.) Attach the feet to the tank. 1.) Unscrew the regulator from the compressor. This can be tricky, but I found that using an adjustable wrench if I went lefty loosey on the bolt where the airbrush hose connects, the regulator unscrewed from the compressor. OR use a THIN* 14MM open end wrench and unscrew the connector between the compressor and the regulator directly. (THIN means 5MM or less) 2.) Remove the feet from the compressor 3.) Attach one end of the pipe to the square 90 by fitting it inside the opening and pushing two o-rings to the fitting. Loosely screw the connector on. Do not tighten as you'll need to adjust it later. 4.) Attach the other side of the square 90 to the opening where the regulator came out. Snug it down but don't tighten yet, you will need to ensure the flat side of the pipe attachment is on the front and back. The pipe will need to be vertical 5.) On the tank there is a smaller opening and a larger (1/4 in) opening, put the appropriate fitting into the smaller opening where the larger part is facing out 6.) Set the compressor on the tank fitting the pipe into the opening of the fitting you just placed, you may need to adjust the positioning of the pipe vertically to ensure it seats in both the upper and lower openings. Once that is done, pull the compressor off the top of the tank 7.) With the compressor off the tank, loosen the square 90 to a position where it is possible to tighten the compression fitting on the pipe, and ensure it is snug. Make sure the font and back have flat sides on the bolt. Tighten the Square 90 into the compressor completely ensuring the pipe is vertical. You'll see the compression fitting is nearly flush with the compressor, thus the need to have a flat side there and not a corner. Set compressor aside 8.) put the nipple into the other opening on the top of the tank, and put the rounded 90 on the other end of the nipple 9.) If you have not already done so, remove the connector from the regulator that was used to connect to the compressor, and screw the regulator in to the rounded 90 and tighten ensuring the moisture trap is down. 10.) Add the Red fitting to the of centered hole toward the top 11.) Add the drain fitting in the bottom 12.) Set the compressor back on the tank 13.) Use the included screws and nuts to attach the feet of the compressor to the tank (it will be a tight fit due to the nipple being vertical. It is possible to change this arrangement, but I didn't want my regulator sticking out from the compressor and tank.) 14.) Snug the bottom of the pipe to the fitting 15.) Plug the compressor in and fire it up. If you got really lucky you'll have no air leaks. I didn't get lucky and had to do a little rework on a couple places, but it was pretty painless. Soapy water makes it easy to see where the leak is. Note: it's going to take a some time for the compressor to kick off. Just about the time you think you messed up is when it will shut off.
Review: Good little air tank - All in all it's a good air tank for the cost. Mine did arrive with rust in the threads, and missing hardware. However it mounted my badger TC909 like it was made for it. As others have said no instructions are provided but realistically its soo simple to assemble they are not needed. I had to assemble and then disassemble a few times for correct assembly order. I used the kit supplied tube and fittings to connect the compressor to the tank, although the o-rings seem cheap it sealed first try. Overall it's a great addition to an airbrush compressor if you want to hear the compressor kick on less frequently.

## Questions & Answers

**Q: Will this tank kit fit my airbrush compressor?**
A: Mounting hole spacing width = 3.75", Mounting hole spacing = 5.75". Please measure your compressor's outlet threads and mounting hole distance to avoid misfits.

**Q: How long is the included tubing? Is it extendable?**
A: The metal air hose is 4.33" long(Dia.0.31"), plastic air hose is 6.69" long(Dia.0.27") long and cannot be extended. Please confirm your compressor's outlet is within this distance from your air tank location.

**Q: Why is air leaking from the connections?**
A: Leaks are almost always due to improper installation: (1) Seals not fully seated in grooves, (2) Under-tightening, (3) Missing tape. Tighten firmly but do not overtighten—this damages threads. Check each joint systematically.

**Q: Are the mounting holes adjustable?**
A: No. Hole locations are fixed at 5.9" long, 3.9" wide spacing. Some compressors require drilling new holes or using an adapter plate. If your compressor's holes don't align, do not force it—this will damage both units.

### ⭐ Straight garbage, deserves negative stars!
*by 2***C on June 26, 2024*

This kit is VERY do it yourself...as in go out and try to collect parts and pieces you will need to complete it. There is a whole bag full of parts and fittings, with about half of what will be useful. Expect that your compressor will not line up with the ports and mounting locations on the tank. You will need to bend the hard supply line from the compressor head to the tank (and it doesn't bend easily). I have no idea what the flexible braided line is for because there are no fittings or clamps that would make it useful. The threads in the tank will be rusty and/or painted and need to be cleaned out or you may just end up stripping the few fittings that are useful. The big secret to all these kits (or trying to hook up your airbrush compressor to any tank) is, the fitting you need to hook up your water trap/regulator is pretty much nonexistent. It's certainly not provided in this kit. Good luck finding what you need. Chances are VERY slim it will be at any hardware stores and will be near impossible to locate online. Good luck and enjoy the extra cost! By the time you round up and pay for extra fittings you will need, you would be better off spending $80-$90 for a Timbertech compressor with tank already installed. I may look at returning this pile of steaming garbage and doing just that.
