وحدة مضخة وقود DW400 مع مجموعة إرجاع PTFE لسيارات Silverado/Sierra 1999-04

The PTFE return kit lines are a huge upgrade over the stock rubber ones, and the pump itself dropped right into my 2000 Sierra's bracket with no modifications needed. Took about an hour to swap out, and the truck fired right up without any priming issues.

Had my Silverado's fuel system upgraded with this DW400 module and the PTFE lines—the drop-in fit saved me hours of fabrication work. Fires up instantly now and no more ethanol worries with the stainless braided return setup.

The PTFE return kit was the main reason I grabbed this, and it made the install straightforward since I didn't have to worry about ethanol eating the lines. The module dropped in without any modifications, and my old truck's fuel pressure is steady even under load.
