宝马 5系7系 E34/E39 汽油泵芯 0986580129 16141183176 低压油泵替换。

When your BMW 5 Series (E34/E39) or 7 Series experiences hard starting, weak acceleration, unstable idle, or sudden stalling while driving, this usually indicates aging or worn low-pressure fuel pump core, leading to insufficient fuel pressure. This component normally feeds fuel from the tank to the high-pressure fuel pump to maintain proper fuel-air mixture and smooth engine operation. This is an original factory replacement, OEM numbers 0986580129, 16141183176 and DK-084, fully compatible with BMW 5 Series E34/E39 and 7 Series models. Installation notes: release fuel system pressure first, clean the tank opening and sealing surface, and perform a fuel pressure test after replacement to ensure no leaks.
