Detailed Description

When the fuel pump seal hardens, shrinks, or deforms, the pump-to-tank connection can lose its seal and affect fuel delivery. This URO fuel pump O-ring is made to replace the failed seal and restore the interface between the pump and tank. It is a fitment-based replacement for Volvo XC70, S60, V70, and S80 models with a metal fuel tank, and it uses an OE-style design for straightforward installation and long service life. This part cross-references Genu 8634839 for the same application.

What It Helps Fix

• Fuel odor around the tank area
• Seepage at the fuel pump mounting point
• Poor sealing between the pump and tank
• Fuel delivery issues caused by a compromised seal
