The FLS-U Tank Fitting Under-Ring is a crucial component designed specifically for use with FL-2 or S5 sender systems in fuel tank installations. This high-quality stainless steel accessory comes complete with 5 x M5 stainless steel screws, ensuring durability and corrosion resistance in demanding environments.

This under-ring serves as an essential interface between the tank and the sender or flange. When used in conjunction with the S5 sender or FL-2 flange, it is securely fitted to the underside of the fuel tank, providing a standardised SAE 5 hole pattern. This configuration allows for a secure fitment on tanks with a thin or flexible top skin.

The FLS-U Tank Fitting Under-Ring can be utilised to mount either an S5 sender or an FL2 flange, depending on your specific requirements.

[NOTE: It is important to be aware that the hole pattern on the FLS-U Tank Fitting Under-Ring is not equally spaced. Therefore, careful alignment with the bolts is necessary before fitting it inside the tank. This attention to detail ensures proper installation and optimal performance of your fuel system.]
