The most common O-rings are the buna the black ones. Two durometers 70 for most mobile applications 90 for static applications (boss type fittings ) . Viton would be the brown ones high heat and special apps but they're a PITA they cut / nick real easy.
Everything seems to be throwaway nowadays these kits have saved me more than once.

Thanks for the info.
Those kits do savey you a lot if trouble and inconvenience.
I have 2 Harbor Freight standard US size type kits and a Metric one that cost less than $8 from Auto Zone.
The Auto Zone kit does not have the Lift Pump O-ring but it does have 24 of the Oil Filter bottom Stem O-Rings and the Lower Fuel Filter Bolt O-ring sizes.
I have not seen it yet but in their ad Harbor Freight is now selling a Metric O-ring kit.
