وحدة مضخة وقود DW400 لـ 1999-04 Silverado/Sierra

First time replacing a fuel pump on my '03 Sierra, and this module dropped right in without any modifications. The pump is noticeably quieter than the old one and my truck starts instantly now.

Took about two hours to drop the tank and swap, but the 4.8L fired up on the first crank and idles smooth as stock. The module fit the 1999 Silverado mounting points perfectly, no trimming needed. Worth every penny for the peace of mind on a daily driver.

Finally got around to swapping out my old pump, and the DW400 fit the tank perfectly without any modifications. Idle pressure is steady at 58 psi, and the truck starts instantly now even after sitting for a week.
