Key Features & Benefits – EPMAN weld-on aluminum fuel filler neck, silver, 2.5" (63.5mm)
The EPMAN weld-on aluminum fuel filler neck, silver, 2.5" (63.5mm) is designed to be welded into a tank wall for custom fuel tanks, water tanks, coolant reservoirs, and other fabricated metal tanks. The weld-on layout helps you place the fill point where routing and packaging require it.
The body is 6061-T6 aluminum, sealed by a screw cap with a rubber sealing ring. The cap has a knurled edge for grip, and the unit is a non-vented design.
When is this useful?
It suits builds where you want a sealed weld-in fill point and need the 63.5 mm neck OD to match your hose/tube routing while keeping cap access predictable.

Selection & installation tips
- Hose/tube match: Match the 63.5 mm neck OD to your hose/tube and clamp choice.
- Flow check: Compare the 45.0 mm neck ID to the rest of your filler path to avoid an unwanted restriction.
- Packaging: Confirm clearance for the 35 mm length with cap so the cap stays accessible.
- Venting plan: Because it is non-vented, plan tank venting separately within your system design.
- Weld fit-up: Dry-fit the orientation so routing does not preload the joint after welding.
Before welding, verify your hose/tube sizing, cap clearance, and venting strategy, then compare them to the listed OD/ID and the length-with-cap dimension.
