Common Concerns Answered
Is this deck fill worth the higher price compared to basic models?
While the initial investment is higher, the Attwood deck fill provides critical safety features like integrated pressure relief (1 psi) and diurnal emission control, along with automatic nozzle shutoff, which offer significant value in compliance, safety, and preventing fuel spills and tank damage.
Will this deck fill create a perfect seal on older or non-standard fuel tanks?
This deck fill is designed for standard marine fuel tank installations. For older or non-standard tanks, ensuring a properly prepared mounting surface and using appropriate sealing compounds is crucial for achieving a watertight seal. Refer to the installation manual for detailed guidance.
I'm concerned about potential leaks. How can I ensure a good seal?
Proper installation is key. Ensure the mounting surface on the deck is clean, smooth, and free of debris. Use a high-quality marine-grade sealant specifically designed for fuel tank applications and securely fasten the deck fill according to the installation instructions provided.
Frequently Asked Questions
What is the purpose of a pressure relief system in a deck fill?
A pressure relief system, like the dual 1 psi safety valves in this Attwood deck fill, prevents excessive pressure or vacuum buildup within the fuel tank. This safeguards the tank from structural damage and ensures safe operation by releasing pressure above 1 psi.
How does the Attwood Deck Fill prevent water from entering the fuel tank?
The deck fill features an angled body and a tightly fitting, hinged scalloped stainless steel cap. This design inherently directs water away from the fill opening and creates a barrier to prevent water ingress into the fuel tank during washdowns or rain.
What is the pressure relief setting for this Attwood deck fill?
This Attwood deck fill is equipped with dual safety valves set to relieve pressure at or above 1 psi, ensuring the fuel tank remains within safe operational pressure limits.
Is this deck fill compatible with ethanol blended fuels?
Yes, this Attwood deck fill is specifically designed and certified for compatibility with ethanol blended fuels commonly used in marine applications.
What nozzle types are compatible with this deck fill?
This deck fill is designed to be compatible with standard marine refueling nozzles and features automatic nozzle shutoff functionality for nozzles operating within the 4-18 gpm flow rate range. It also meets ISO 13331 nozzle mating and retention standards.
