Review on 🔒 High-Quality iFJF TP3018 Fuel Filter Replacement for Duramax 6.6L Chevy Silverado/GMC Sierra 2500HD & 3500HD 2001-2016: Reliable Performance for Diesel Engines TP3012 12664429 by Gregory Castellanos

I didn't get a good answer as to whether IJFJ cast their own filter heads or just repackaged them, but I had trouble getting my filter to seal after a good install. During the first disassembly I found some aluminum shavings left over from the machining process! The support guy went above and beyond for me and after a month the truck still hasn't let me down but if you buy this product a thorough inspection and cleaning before installation is in order. Otherwise good looking product.
