Instructions - Fuel Diamond
Main menu:
NB The Fuel Diamond is guaranteed to keep fresh petrol fresh. It will not ressurect old fuel that has already become stale or clean out fuel systems where petrol has already emulsified.
Installation:
Simply drop the Fuel Diamond into your tank via the filler cap or the sender unit hole.
Keep the Fuel Diamond inside the black ethanol-proof netting as this prevents it rattling inside your tank.
One Fuel Diamond treats up to 60 litres, refill after refill (larger tanks will require 2 units).
The Fuel Diamond lasts for 5 years and there's no need to remove it as it can stay in the fuel tank permanently.
