Chase Bays Raised Inline Filler Neck | Universal (CB-IFN)

Universal Fitment Raised Inline Filler Neck by Chase Bays

A major issue with some engines (especially engine swaps) is the difficulty in bleeding the system. The fill point on the radiator is lower than the coolant passages in the cylinder head or the heater core. This causes unsolvable air bubbles that continue to accumulate as the system cycles. Even when you use coolant bleeding kits, it puts the cap and overflow point below those coolant passages. This causes the cap to overflow more fluid per second if the pressure level of your cap is exceeded. All in all, its an issue enthusiasts have been dealing with for decades.

The Chase Bays filler neck raises the fill point 3.75" inches / 95.25mm from the center of lower fitting to where the cap seal ends (not the very top). The total height from bottom to top is 5.25" inches / 133.35mm. It installs by welding one of the adapters directly to the upper water neck. You can see example photos below. You can also butt the filler neck up to the water neck and use a short piece of hose to connect the two. That method will take up to 3" inches / 76.2mm more space, but in some scenarios space is not an issue.
