Review on 🔧 Lang Tools TU-470B Fuel Injection Cleaner: Boost Engine Performance and Efficiency by Gabriel Day

Unfortunately I give this one 3 stars. I like that it's a lot cheaper than the Matco brand, about half the price. I'm pretty sure they are physically identical because they work and look the same with the fittings on my Matco MIT550. Comes with a fitting that I can connect to my catenary. I pressed it, after a small repair I found that the pressure gauges on the inlet and outlet coincide and the regulator rotates smoothly. The downside is that the bottle didn't screw right out of the box. Found the threads were damaged and I had to fix it with a triangular file to screw the bottle all the way. QA in assembly or boxing leaves a lot to be desired.
