U were spot on man about the plug. I got a fuel rail plug and have had in my truck for 3 years and no issues. Its the rail spikes that give fuel plugs a bad name but like u said knowing how to drive your truck will make the difference. And on a stock fuel system a rail plug won't do anything really good assurance tho to insure u getting good rail pressure but people rarely hit 24k psi lol

Ya man I tried and I can’t hit 24k haha. But left it in there because why not, and I’ll need it when I get my bigger 12mm cp3

Unless you’re running 2 cp3s, insane tunes and you’re modded for pulling you really don’t have to worry about this cracking injector bodies. On a Duramax with over stock injectors, lift pump of your choice and a trusted tune you’ve got nothing to worry about. I run this on my LB7 Duramax with 70 over injectors, a fass lift pump, stock cp3, and a reputable tune and I’ve never had so much as a hiccup. Truck runs 100x better after putting this on and getting rid of the stock pos. Any diesel shop can explain a little better what it does and doesn’t do and wether it’s a good idea for you or not after telling them what all is done to your truck. Best of luck to everyone and great video.
@smittys19daytona9 ай бұрын
were you having issues before you put the 70 over injectors in and the plug made a difference ? or being oversized you needed more pressure, because the stock relief valve bleed off?

I ran one on my 04.5 6 speed Cummins for over a year and over 130k miles. Never had an issue. Tune 5, 40+psi of boost, towed 26,000(non cdl) pounds for a living cross country(700 miles a day at times). Engine lasted until 438k before it blew a compression ring but it wasn't related. That's my experience. I would run one again if I didn't 12 valve swap the truck.

Love the video, I’ve been a duramax guy all my life but really been thinking about/ gonna go to a 2018 Cummins with the cp3. My plans for that are a full delete, on the fly tunes with my last one being pretty spicy, 100 overs, larger turbo such as s475 or something, intake, ccv delete, upgraded cooler with tubes, monster ram intake horn, and a 12 mil lift pump. With all of that on a stock cp3 (I promise I don’t beat on my stuff so the injection pump should last a while) do you think my rail pressure will excede the 25000 psi and me needing a plug? And feel free to include any information you would like as I’m very new and learning about the 6.7 cummins

the springs in those things are known get weak over time and they start to open way early robbing your rail from sufficient pressure i personally have had a plug in mine for a number of years now but i have a edge monitor in the cab so i can keep an eye on the FRP and have never been able to exceed the 25kpsi. just buy a new FPRV for peace of mind if you dont a way to monitor fuel rail pressure
