Description

PERKO 1-1/2 in. Inlet Check Valve and 5/8 in. Surge Protector Combo – 30-DP0-005

PERKO part 0030DP0005 is an aftermarket fuel-fill service kit designed to reduce refuelling spitback and wellback. The inlet check valve sits in the fill hose near the tank, while the surge protector sits in the vent line near the fill or tank vent to help the fuel nozzle shut off more predictably and reduce fuel discharge.

Key Features

• Includes both components required to address fill-hose wellback and vent-line spitback
• Sized for standard 38.1 mm (1-1/2 in.) fuel-fill hose and 15.9 mm (5/8 in.) vent hose
• Compatible with plastic or metal fuel tanks
• Allows unobstructed airflow at refuelling rates up to 68.1 L/min (18 US gal/min)
• Usable with EPA-compliant marine fuel systems
• In-hose designs minimize added fittings and potential leak points

Installation and Application
