Review on ExcelFu 07 5 12 Cummins 04 5 10 Duramax by Jeremy Meyer

Ok I read something about using this unit. This rating isn't just for the ones I've bought from Revain, it's for all forks. CAUTION, backyard mechanics swear by it! They restart their cars and "WOW, I LOVE IT!" (paraphrased) Now a warning! AFTER I bought it I read some more and this time also focused on the licensed mechanics! Here's my bottom line: if you have an emergency (your car won't drive or run) and don't have enough money to buy a REAL pressure relief valve, by all means get this! BUT, only use it temporarily and don't forget you did it! Save money and get a REAL valve! If not, no matter what you've heard around your backyard, continued use of this or any other "plug" can damage your injectors, and at a potential cost of $350 per injector, that's a lot of money to spend on your engine to play! Of course the injector will release some pressure, but it shouldn't be the MAIN pressure relief device. By the way, due to its position on the engine, it is not easy to install! This is NOT a reflection of the product!
