OEM is not Viton !
70 Duro would be enough for the pressure and temperature, just saying
Like who pulls their Pump apart anyhow?, it works in the 40psi range and the fuel doesent get very Hot, you Hope!

Viton O rings are for high pressure/Temp environments like in Hydraulic systems IMO

yes but if and when you clean the fuel filter you need to change them - and for that you need to HAVE them. Thats the point here.
They may be too good for the job but considering much of the Hima is the opposite thats a nice change

Having removed the pump from its plastic housing I can tell you it is not an easy job to do with just 2 hands.
Knowing the meaning of the colour of the O ring and the hardness ie Durometer I can say that fitting Harder Higher temperature chemical resistant O rings is waste of time and money IMO
