🔧 Durable Diesel Fuel Injector Return Line Rail Kit for 2004-2010 Chevy GMC 6.6L LLY LMM LBZ Duramax Engine - High Compatibility Guaranteed Review

Automotive diesel injectors are crucial components for engine performance, and after trying a few different options, I found a compatible one which is a great fit for my 2004-2010 Duramax. Thanks to its efficient fuel delivery and design, the injector has made my car run much smoother and more efficiently. The only downside is that the price can be quite high for some buyers, but in the end, it is worth the investment. Through trial and error, I recommend this diesel injector for anyone who…

Good kit I like the metal fittings and the line, it looks very nice. Seems to fit well. The biggest problem I found was that the kit included an extra tee and due to the lack of 90 I had to reuse 90 from the old hose. I would give five stars if the details were right.

Don't get those fuel return lines, they are not reinforced at all and will snap and fall off! I've driven 600 miles and had to stop 6 times along the way to change fuel lines. Ps, one of the screw connections did not close completely, also my original plastic was reused with a new O-ring. A bad item overall, and if the exhaust gets hot enough and spills fuel, there's a chance your truck will catch fire.
