Overview
The Attwood Marine 99DFPVSB1S is a straight-body deck fill for pressure relief fuel systems, with a scalloped black plastic cap and hose connections for 1-1/2 inch fill hose and 5/8 inch vent hose. It uses dual 1 psi diurnal emission control and overpressure relief valves in the cap, along with triple high-flow vacuum valves to manage tank pressure during fueling and normal fuel draw.
This fill is built for boats that need cleaner refueling behavior at the dock. The automatic nozzle shutoff works from 4 to 18 gallons per minute, which helps the system reach the proper fill level without the usual spit-back and well-back problems that can make marina fueling messy. It is also built to keep water out of the fuel system and is compatible with ethanol-blended fuels.

Installation and fit
This model makes sense where the hose run below the deck works with a straight fill body rather than an angled fitting. Before ordering, confirm that the boat is set up for a pressure relief fuel system and that your existing hose sizes match the 1-1/2 inch fill connection and 5/8 inch vent connection.
On a retrofit, the key question is not just deck appearance, but system layout. This fill belongs in a matched pressure relief setup, so it is a better fit for boats already using compatible Attwood system components than for an older open-vent arrangement.
Compliance and system use
This fill meets the current standards commonly checked on regulated fuel-system installs, including EPA and CARB requirements, CARB 13 CCR 2235, ISO 13331, ISO 10088, and CE compliance. That matters on boats where evaporative-emissions control, nozzle retention, and controlled tank venting are part of the fuel-system spec.
It is a practical match for center consoles, bay boats, and cruisers that refuel regularly at marina pumps and need pressure management built into the fill itself. For owners replacing a worn deck fill in a compliant pressure relief system, this part covers the details that usually decide fit: hose size, fueling rate, cap style, and standards compliance.
