Product Details

The Moeller 033303-10 is a premium marine fuel shut-off valve designed to connect two permanent fuel tanks to a single outboard motor. Constructed from forged brass for maximum durability and corrosion resistance in harsh marine environments, this 1/4-inch valve provides reliable fuel flow control and safety features essential for boat fuel systems.

Key Features:

  • Forged brass construction for long-lasting durability and corrosion resistance
  • 1/4-inch female/male NPT connections for easy installation
  • Enables switching between two permanent fuel tanks feeding a single motor
  • Built-in anti-siphon protection prevents fuel backflow and accidental drainage
  • Meets ABYC H-24 standards for marine fuel system safety
  • Suitable for gasoline and diesel fuel applications

Important: This valve is designed exclusively for marine fuel systems and must not be used in potable water systems. The anti-siphon feature ensures safe operation by preventing fuel from siphoning back through the system when the engine is not running.

Ideal for boats with dual fuel tank configurations, this shut-off valve provides convenient tank selection and enhanced safety compliance for your marine fuel system.

Great so far

Only place I found that had the product I needed. Extremely satisfied!

This was my first time buying from Autoplicity. I had never heard of the site but gave it a shot. I ordered an Autometer gauge and pod and paid less than the price of just the gauge at other vendors. The two items shipped a day later (I ordered Sunday, shipped Monday). I have no complaints at this time.

nEED ASAP

Return customer, excellent communication and fast shipping A+

The site was easy and I found what i needed quickly with a great price. Thank You

Y'all is Awesome!

easy check out!

It was fast and easy ;) I cant wait for my stuff to arrive

Very easy to place order

I haven't received my order yet but I am satisfied at how fast the order was processed and shipped. The website was very easy to navigate and best of all the prices were hard to beat. I believe I will be visiting this site again.
