Dear Mark, Because of Ethanol in the fuel (5% at present) and at some point in the future going to raise it to 10%, are the drive side and mag seals able to cope with this? and of course is the MBU 0431 petrol pipe, the MRB 0031 race tour drive side bearing with fitted seal and all the inline fuel filters you sell able to cope with Ethanol too?

Accepted Answer

Our MB Viton seals are the best material for this problem. The seal on the drive bearing doesn't matter. Fuel pipe and filters are simple throw away items if they get effected but we've seen no problems yet
