Autozone sells a Metric O-ring assortment made by Dorman for less than $8.
Dorman 172 piece O-ring Value Pack #799-450
In it are 24 of the 6mmIDx10mmODx2mmW O-rings that you need for the bottom of the Oil Filter Stem.
While the pats places sell 2 of the same sized O-rings for the bottom of the Oil Filter Stem some people use a 7mmX11mmx2mm on the upper one. There is also 24 of those in the Dorman Kit.
As previously stated start by changing the Fuel Filters.
Other things that can cause the issue:
An Air leak in the Fuel Inlet hoses and/or Hand Primer Pump.
(I will let this long thread speak for itself.)

Sloppy Throttle Linkages can cause hesitation.
If your Fuel Supply/Lift Pump is not doing well it will not supply enough out put when needed. I believe that could also cause a hesitation.
In the manual there is a Vacuum test as well as pressure tests for the Fuel Supply/Lift Pump and the Fuel Pressure/Overflow Valve.
