Description
This Viton-Based O-ring fits the fuel pump assemblies on externally mounted fuel pump flanges. If you are replacing your fuel filter, there’s a good chance you’ll need to replace this oring. The oring tends to deform when the fuel pump assembly is removed. Our oring is less than 1/3 the cost of the OEM oring.
Model 1 – Ducati 748, 916, 996, 998, ST2, ST3, ST3S, ST4, ST4S
NOTE1: It’s VERY easy to pinch/cut the 1 oring during installation. I’d order a spare just in case. I’ve ruined dozens of them over the years during installation. The flange/oring are a TIGHT fit. Lube is your friend.
NOTE2: I no longer carry other variants.
