🔧 Professional Master Fuel Injection Service Kit - OTC 6550PRO Review

Used to purchase a cheaper S&G ToolAid fuel pressure tester. It used threaded connections and had leakage issues as well as some other quality control issues. I tried using this and it was a lot easier with the quick couplers and I was able to hook it up to a '92 Ford Ranger. No leaks and it was easy to connect and disconnect.

This is a great set, especially compared to the prices of tool trolleys, but I was a bit surprised to see that it goes before 2008, ie I wish it was just a little bit more modern, but overall it's worth the money. I especially like the book that tells you what adapters are needed, where they plug in, and what fuel pressure is normal for your particular model year.

I work on a variety of vehicles at an independent auto repair shop and this Master Fuel Injection Kit is a must have. Very well presented. Fits and ends great. This is an expensive set but it has returned my money many times over. I couldn't do my job without him. I also have OTC Fuel Injection Cleaner.

I'm a dyer, not a car mechanic, but I can tell you that I am. I used this and it works as it should. Price when purchased separately. You will spend more. That's why I chose this one. This isn't a $40 tester, it goes beyond the chopper valve. Where the cheaper ones stay. You can check the fuel tank before the filter or if you have a car with a fuel tap you can check it. This is an OTC, well built, well worth the money.

Great set, very complete. This set appears to be of high quality, however one of the hoses fell off my desk and the quick connector was bent so I couldn't use it. I spent thirty minutes bending it to proceed with the diagnosis. I want to say that this product is very expensive and must withstand the daily conditions of the store. When I first used it it couldn't handle a single hose drop from 4ft. That says something about the quality of the materials that make up this set. I still recommend…

I was looking for a complete injector test kit. I had an old Mac toolbox that was fine, but I always needed adapters that I didn't have in the box to make the connection. After researching and speaking to a few others I settled on the OTC 6550Pro based on the recommendation. I've had it for about two weeks and so far it hasn't let me down. The companion book describes the 2008 model year vehicle fuel system pressure in great detail. The parts are well made, the connections are tight, no leaks…
