OTC 7448A Fuel Injection Cleaner Tool - Use Tool with Compressed Air and Cleaning Chemicals for Effective Direct Fuel Rail and Injection System Cleaning

This is a quality tool and seems to be built well. It doesn't come with the cleaner so you have to buy that separate. Since I didn't know this when I purchased it, I found that one of my local auto parts dealers (only one of the national chains carried it) could order it in within 24 hours for a little cheaper than the online price. This tool can be reused many times which really helps since my wife's 2005 Land Rover LR3 has a chronic problem with dirty fuel injectors. I had to purchase a standard air tool connection for the top of this tool in order to hook it to my compressor hose. It doesn't come with it. I also had to purchase a 3/8" brass elbow to a 1/4" fuel hose connection to hook it up to the 1/4" fuel line hose. Otherwise, it came with everything needed (as well as a manual) and worked really well. Sure beats in fuel cleaners for the tough jobs.

This is a well made tool i would recommend this tool to everybody execellent tool for the job easy to use for everyone who buys the tool or even thinks about buying the tool you will need to purchase the connectors separately or if you have a fuel pressure gauge setup lying around just take the hose off of it and ad it to the fuel cleaner tool then you are ready to go.

I use Berryman B-12 Chemtool fuel system cleaner with this tool and have had improved performance every vehicle I have used it on. 5 of my own and 7 friends vehicles. The trick is finding the appropriate place to intersect the fuel line. Most can have fuel line disconnected and a hose with hose clamps connected using the slightly lower air pressure to keep the engine running without the fuel regulator by-pass opening sending the fuel system cleaner back to the tank. OTC probably does not condone some of these innovations but the tool works using the included manual. The Berryman cleaner cleans injectors, lines, regulators and valves among other parts. I have done a couple vehicles more than once with notable performance increases.

this fuel injection cleaner worked very well to clean the injectors on my truck. truck runs much better. only issue is the adaptors are only made by otc and are very expensive. otherwise this is a very good tool and works much better than the pour in gas tank cleaners.

This product is exellent, does exactly what it claims. Is also very easy to use. The reference manual is a huge advantage, especially if you work on several different car lines.

This tool works great and was easy to use. I used it with the Seafoam product. It says on the can that it can be used in injector cleaning machines. The engine fired right up on the straight seafoam. There are a few youtube videos on how to set everything up. Additional note: On the two cars that I have done so far, I got a check engine light for cylinder miss fire, so be prepared to reset the light when your done.

Had to return for a replacement . The replacement had the same problem were the check valve sticks and won't release gauge pressure.Make it unable to set cleaner pressure.

I've cleaned two vehicles so far, and both have better throttle response, fuel mileage, and power. Very well built and it comes with clear instructions. Definitely worth the price.

This is the tool to clean fuel injection systems. It works (connects) with my other fuel pressure test kit and allows the introduction of the fuel cleaner to the fuel rail. If you are a automotive technical you will appreciate the OTC brand. Glad I bought this item

Exactly what I wanted!

plug into air line and added pressure. the gauge is stuck, notice the otc pressure display is pushing outward causing the needle to get stuck, even back off the pressure and release all the air inside the gauge does not return back to 0 psi. there is no support yet, unable to use it at this time, will be update the rating once i get the gauge replacement or i have to return the product.

I'm a service technician and we have similar OTC fuel injector kits in our shop. OTC is good stuff for special service tools and they come with a price. Having your own beats looking for the tool or waiting for it. If your like me and have your own fuel fittings for OTC then this tool is the way to go. I had to remove one of the valve cores so the fuel would actually go through. Other than that it works.

I followed the operating instructions provided, and at step 12, when I slowly adjusted the regulator by turning clockwise to bring the pressure to the vehicle specification, at some point, the gauge went from zero to 52 PSI within a second, and stayed at that position. I undid everything, and even with the top cap removed and zero pressure, the gauge still reads 52 PSI. Clearly a defective gauge. Not impressed.
