🔧 Enhanced OTC Tools 7448A Fuel Injection Cleaner Canister for Advanced Optimization Review

This is a well made tool. I recommend this tool to everyone. Great tool for the job You will need to buy the fittings separately or if you have a fuel pressure gauge just remove the hose from it and attach it to the fuel cleaning tool and you are good to go.

Factory packaging has been opened by someone before. The Revain shipping box fell apart. This was most likely purchased by someone else and then returned. I bought and paid for a brand new device so just sent it back to Amazon but unfortunately I didn't have much time and had to use it.

I usually like OTC products. They are well made and mostly have their own body. Unfortunately, this tool was a big disappointment. I bought it at the end of November but haven't been able to use it until today. That gave me a lot of headaches. First, no fuel rail adapters are included. You must purchase them separately. I bought an OTC Pro 6550 which is very well made. Second, the pressure gauge didn't work. No pressure below 50 psi was recorded. No matter how I adjusted the regulator and my…
