2003-2007 GDP 5.9L Cummins Mega-Rail System
Now there's a way to fuel that fire breathing 5.9L your building with Bosch certified parts. The GDP Mega-Rail System!
The Mega-Rail System includes everything needed for installation of the entire fuel rail system from the larger 6.7L applications onto the 5.9L Cummins. This simple bolt on package gives the 5.9L Cummins an edge in airflow and fueling like never before. Finally you can get the most from your modified injection pump and performance injectors!
Using our Mega-Flo Intake Manifold, Air-Boss 67 plenum and factory Bosch HPCR parts we have created a package that is reliable, easy to install, and out flows any other parts combination on the market. If you're pushing the envelope on 5.9L Cummins performance the Mega-Rail kit can fuel it.
Benefits of the Mega-Rail System:
• 50% increase in fuel rail size – Perfect for modified CP-3’s
• 50% increase in fuel rail feed line size – Matched to rail size
• 50% increase in injector line size – Handles even the largest injectors
• 50% increase in crossover tube size - Removes the final restriction in the CR system
• 3000 psi higher relief valve pressure – No need for rail plugs, we leave the safety in the system
• 110% increase plenum entrance area – Over double the air entrance area at the plenum
• 20% larger intercooler piping - 3.50” Intercooler piping and intake manifold vs. 3.00” stock
• 100% Brand new Bosch fuel rail, injector lines and crossover tubes - No concerns over used or modified parts
• 100% Bolt-on installation - It doesn't get any easier than this!

1st thing, Richard is an excellent resource for upgrading your 3rd Gen Cummins. Ive purchased several products from him, and just as expected, this product is something truly amazing. The craftsmanship and finite details in this kit are top notch! Perfect tolerances and fit on every part. Everything bolted in easily, exactly as described by GDP. Kit came with everything needed along with excellent packaging, high end parts, etc…
Now, the performance is amazing. Im running other Diesel upgrades including an ATO Performance tranny, but this kit compliments and pushes everything else above and beyond. Its Amazing to have a 1ton Diesel that can move and accelerate as fast as it does now.
Excellent product! A++ service from GDP and excellent communication. Answers questions via email very quickly. Thanks again GDP / Richard. Your products are 2nd to none!
