-12 AN Water Pump Block Adapters

These CNC machined adapters bolt onto the engine block in place of a regular cast water pump housing, and convert the water passages into a -12 AN "0-ring"fitting. This then allows you to use reguar AN style braided lines to route the cooling lines however you prefer. This can include things such as an externally mounted electric water pump, reverse flow (so that the heads are cooled first, before the cylinders,) etc. Also, if you are using a gear drive, belt drive, or thicker timing cover that does not fit under a cast water pump housing, these are a great solution for that as well. Supplied in a pair (1 left hand and 1 right hand piece.) A cool part at a great price!
