This is very good advice.
Buna-N 'O' rings (commonly called Nitrile) are generally said to have good fuel resistance but the nitrile percentage varies considerably and influences the properties of the finished compound.
Those with a high nitrile content are ok for fuel but the market is flooded with 'O' rings having unknown composition from places like China. A low nitrile compound is not ok for fuel so only buy 'O' rings from a reputable source.
It sounds like you guys have got it now:-
