PPE Ported Fuel Rail Fitting for 2004.5-2010 Duramax LB7 LBZ LMM 113071000

Just as described! Great replacement part!

This worked out great for keeping fuel flow consistent in my fuel rails on my LLY duramax!

Okay, I just got done installing this on my truck. Not a hard job at all it took about 30 min total I only installed it on the drivers side it’s the only one that needs to be replaced if anyone is wondering. Now, let’s gets down to does this fitting make a difference all I can say is HELL YES! The throttle response is where you see a difference it is amazing it’s now very touchy and quick on take off. This part changed the way the truck drives totally and for some reason the trans shifts a lot smoother. My truck is stock with no tuner sporting 200k miles. I use my truck to tow a 11k fifth wheel and I’m heading on a trip in about 3 weeks and I will update how it did for all my fellow camper haulers. I did also install the PPE fuel relief valve before I did this and that made the motor run stronger and made it feel healthy so that’s another part I would recommend along with this part.

Improve rail pressure.Like others, check before installing. Noticed machine burrs inside

Good product, but found debris in the hole before it was installed. Cleaned it out, and all was well.

Great product from ppe

Perfect! For and worked great for my 05 LLY. Should’ve been what came stock.

Very nice looking product. Very easy to install. Pull the ac compressor move it out of the way. Pull the little fuel line and pull out the stock fuel rail fitting and replace with this one. The size of the hole is noticeably larger on the new one. 2004 lly
