Attwood Marine Fuel Tank Fitting, For Yamaha, 1/4 in NPT Male, Brass

Overview

The Attwood Marine 8897-6 is a tank-side fuel fitting for Yamaha portable fuel tank connections with a 1/4 inch male NPT thread. It is made from solid machined brass and is built for gasoline fuel systems that may see leaded, unleaded, ethanol-blended, or alcohol-blended fuels.

This fitting connects at the tank, not at the engine or hose end, so it is the part to check when you are replacing a worn tank connector or matching a new hose assembly to an existing Yamaha-style tank outlet. It also fits some Mercury and Mariner applications that use the same connection pattern.

For hose-side connection, it mates with Attwood 8896LP6 and 88FHY516-6 fittings. That makes it a straightforward replacement when you want to keep the same tank layout and restore a secure quick-connect point between the portable tank and fuel line.

Key features

• 1/4 inch male NPT tank thread for Yamaha-style portable fuel tank connections
• Solid machined brass body that stands up well to fuel exposure in a marine setting
• Works with leaded, unleaded, ethanol-blended, and alcohol-blended fuels
• Tank-side quick-connect fitting that mates with Attwood 8896LP6 and 88FHY516-6 hose fittings
• Also used on select Mercury and Mariner setups that share the Yamaha-style connector pattern

Compatibility and fit

This part is a good match when the tank has a female 1/4 inch NPT port and the fuel line uses a Yamaha-style quick-connect at the tank. It is not a universal fuel connector, so the thread style and the quick-connect pattern both need to match before installation.

On older boats and portable tank setups, the quickest fit check is to confirm the tank-side thread size and compare the coupler style on the hose assembly. If your hose already uses the matching Attwood Yamaha-style fitting, this connector keeps the system consistent without changing the rest of the fuel line.

Installation and setup

Because this is an NPT threaded fitting, the thread seal should be made with a fuel-safe sealant suited to marine fuel systems. The brass body is compact enough for typical portable tank installations, but the connection still needs enough clearance for the hose coupler to snap on and release cleanly.

This fitting makes sense for boaters replacing a corroded or leaking tank connector on a portable outboard fuel setup. It is especially relevant on small fishing boats, tenders, and other outboard-powered boats that rely on removable fuel tanks and quick-connect fuel lines.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
