Tall Weld-In Filler Neck with Aluminum Cap – Vented or Non-Vented
This tall weld-in filler neck and aluminum cap kit offers added height and versatility over our standard filler bung setup.

The kit includes a 1.25" x 12 threaded weld-in bung made from 1-5/8" diameter mild steel and a matching aluminum filler cap—available in your choice of vented or non-vented versions. The cap seals tightly with a replaceable O-ring for a leak-free, hassle-free installation.
This setup is perfect for fabricators looking to blend form, function, and customization into one easy-to-install package.
