DW400 燃料ポンプモジュール CPEリターンキット付き 1999-04 シルバラード/シエラ用

The return kit saved me so much headache tuning my 6.0 swap—the lines fit perfectly and the pump keeps pressure rock solid even when I’m beating on it. Took about an hour longer than I planned, but that’s on me for not reading the instructions twice.

Install was straightforward on my 2003 Sierra 2500 with the 6.0L, and the CPE return kit made plumbing clean and simple. Fires right up and holds steady pressure even under heavy throttle.

The DW400 module dropped right into my 5.3L without any bracket tweaks, and the stainless CPE return kit kept the lines clean under the bed. Fuel pressure held steady at 58 psi through a full tank, so the install paid off on the first tow.
