2. Key Features
Heavy-Duty All-Metal Construction: Solid chrome-plated brass body eliminates cracking, crushing, or UV embrittlement common with plastic alternatives, enduring accidental deck stepping and harsh mechanical shocks.
Corrosion-Proof Chrome Finish: Multi-layer chrome plating resists saltwater oxidation, galvanic pitting, and verdigris accumulation in severe marine environments.
Instant Automatic Shut-Off: High-precision internal check valve seals automatically the moment the fitting is disconnected, preventing deck fuel spills and vapor release.
Positive Stainless Steel Lock: Heavy-duty spring-loaded lock clip guarantees secure, vibration-proof latching onto factory male fuel plugs without air leakage under heavy chop.

5. Common Symptoms & Troubleshooting
Engine Hesitation, Surging, or Misfiring at High RPM (Air Intrusion):
Cause: Worn internal Viton O-ring drawing unmetered air into the fuel suction circuit.
Troubleshooting: Squeeze the primer bulb firmly; inspect the joint for fuel weepage or bubbling. Replace internal O-rings or renew the connector.
Fuel Weeping When Hose is Disconnected:
Cause: Dirt, varnish, or corrosion holding the spring-loaded brass check valve plunger open.
Troubleshooting: Depress the valve pin to flush debris; replace the connector if the internal spring has failed.
Sticky or Hard-to-Latch Push Button:
Cause: Salt crust buildup inside the stainless retention slide.
Troubleshooting: Rinse thoroughly with fresh water, apply marine lubricant, and verify smooth locking engagement.
