This kit includes 4 magnets the are placed on the outside of an aluminum or polypropylene fuel tank to facilitate the use of the 16-204 Hydromat Installation Magnet Kit with the #6-32 fasteners. The smaller 16-203 kit with #4-40 fasteners is better suited for steel tanks and smaller Hydromats.
The HydraMat magnet kits are designed as a cost effective solution for mounting the Holley HydraMat in the fuel tank or cell. Ideal for use in fuel tanks with a small sender opening where the Click Bond kits cannot be used. Once installed, the magnets can be positioned so the HydraMat lays flat in the bottom of the fuel tank.
