This coolant/washer fluid reservoir mount is for OBS Fords that came with 7.5 or 5.8 gas engines. It relocates the reservoir to make room for a second battery to mount in the factory location, which is ideal for Cummins conversions.
We also offer this reservoir mount with a mount for a 6 relay/fuse box for a very clean wiring solution for your Cummins conversion or addition accessories. This option comes with the 6 relay/fuse box and mounting hardware. It is up to the customer to supply the relays and wiring.
