Key Features & Benefits – EPMAN weld-on aluminum fuel filler neck, black, 2.0" (50.8mm)
The EPMAN weld-on aluminum fuel filler neck, black, 2.0" (50.8mm) is a weld-in filler neck for custom fuel tanks, water tanks, coolant reservoirs, and other fabricated metal tanks. The weld-on design lets you create a fill point where the original layout is not usable.
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 fits builds where you want a compact, sealed weld-in fill point and need the 50.8 mm neck OD to match your hose or tube routing and available space around the cap.

Selection & installation tips
- Hose/tube match: Match the 50.8 mm neck OD to your hose/tube and clamp choice.
- Flow check: Compare the 35.8 mm neck ID to your filler tube and tank opening to avoid an unwanted restriction.
- Packaging: Confirm clearance for the 32 mm length including cap so the cap stays accessible.
- Venting plan: Because it is non-vented, plan tank venting separately within your system design.
- Weld prep: Clean the weld area and test-fit the neck orientation so routing does not preload the joint.
Before welding, verify your hose/tube size, mounting clearance, and venting strategy, then compare them to the listed OD/ID and the length including cap.
