Adam ★★★★★ Oct 22, 2026

The DW430c pump dropped right into my 2002 GT without any modifications. Everything from the module to the plumbing kit fit perfectly and the car fired up on the first try. Fuel pressure is rock solid now under boost.

Andrew ★★★★★ Oct 21, 2026

The PTFE plumbing kit included made installation straightforward, and the DW430c pump has been holding steady pressure even under hard acceleration. Took about an hour to swap out the old assembly.

Benjamin ★★★★★ Oct 20, 2026

After struggling with sagging fuel pressure on my '04 GT, this X3 module with the DW430c pump brought it right back to life—installation was straightforward with the included PTFE plumbing kit.
