fuel pump o rings

[GregoXB]

I am going to install the OEM fuel pump O-Rings, P0121.02A8A onto my '09 XB fuel pump. What is the correct lubricant to use when installing?

I use Parker O-ring lube. They have a sticky kind, but I like the greasy kind.

Regular motor oil, assembly lube, Vaseline, will be good in a pinch as you only need them to be slick for install and they are obviously OK with petroleum products because they are rated to be submerged in gas.
