THE SURPLUS UNITS were widely used in fuel systems for decades. However, the surplus synthetic rubber seals are not always compatible with current hydrocarbon fuels and/or additives. Earl’s has redesigned the original surplus valves with modern elastomers which are not affected by most fuels and lubricants.
