It is specified for models including 2001-2005 Mercedes-Benz C240 and C320, 2002-2007 C230, 2003-2006 CLK320, CLK500, and CLK55 AMG, 2006-2009 CLK350 and CLK550, 2007-2008 CLK63 AMG, 2003-2009 E320, 2006-2009 E350, 2007-2009 E550, and 2007-2011 CLS550. This part cross-references URO-015495 for the same application.

When servicing a Mercedes-Benz fuel pump tank seal, the correct seal material and dimensions matter. This Viton seal is made to withstand fuel exposure and under-hood heat while helping preserve the sealing surface between the fuel pump and tank.

What It Helps Solve

• Fuel odor caused by a deteriorated tank seal
• Loss of fuel system sealing at the pump-to-tank interface
• Pressure loss related to a failed fuel pump tank seal
• Leak concerns after fuel pump or tank service
• Service issues on Mercedes-Benz C230, C320, CLK350, E350, and CLS550 fuel systems
