B Series Water Pump Inlet


The delete eliminates the steel tube, cast housing, thermostat, thermostat cover, fan switch, and all other unwanted connections. It starts with a custom billet bung that inserts into the block and seals uses a Genuine Honda o-ring. I then cut up a couple of sections of 1.25" 6061 aluminum bends, clock them on a block, and carefully weld them together, and add a bracket to hold it in place.

The end can either be terminated with a bead roll or a custom -16 AN male flare. 

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at If you are using AN lines, I recommend designing the lower radiator hose so that there is droop/ give... so the engines movement and does not push/ pull on the inlet and fatigue any parts.
