Overview

The Wehrli 100402 is a high-pressure line upgrade kit designed for CP3 conversion setups on 2011-2016 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax LML engines. It features a larger inside diameter high-pressure line and rail fitting compared to standard street kits, which increases fuel volume capacity and improves high-pressure fuel flow. This kit supports 10mm, 12mm, and 14mm CP3 pumps and is ideal for high horsepower builds.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
