Review on 🔌 Dorman Diesel Fuel Injector Rail Plug - Compatible with Ford Models - 904-231 by Marty Wainwright

I don't like to criticize the product negatively but I will certainly notify you when the warranty is up. Samples I received: White teflon washers glued between blind plug threads and railport threads. The first plug didn't start to screw in and the second plug started to screw in but its operating torque was too high and I was afraid of damaging the fuel rail lol. Their steel material, unlike my original plugs, reminds me of a cast iron pot. Your 12mm socket was too narrow, I had to insert a socket and then tap back to remove it. My stock pipes (better - come with the latest head gaskets) fit like a glove, so I couldn't figure out why those Dorman plugs were giving me a headache. After spending about two hours trying to figure out what I did wrong, I ended up reusing my old plugs with new o-rings. A book. Didn't come back due to obsession for days. kyle
