Viton orings are said to be more fuel and bio resistant than the buna nitrile rubber MB continues to use. Is a slightly harder rubber compound. Who knows how long they will last? Mine ahve been in for about 3 years or so.....buna will also last at least a couple of years IMO. My DV orings remian Buna; I won't change them until they leak. Have been in for 3 years.

You'll ideally want about 48" of cloth braided or viton return line. Mine is cloth and is original FWIW and I have burned a fair amount of B99 previously, although not recently since it is not cost effective.

The Russian site is the EPC; I've never joined startek since it is there to use. From Russia, with Love.
