A. To convert from existing Heater Core Tubes that exit the Firewall

1. If you are converting your existing Barbed Heater Core Tubes exiting the Firewall use our "Barb to AN Adapters". Accurately measure the tubes ( not the barb) Select from the menu either (3/4" to -10AN) or (5/8" to -10AN) depending on the OD of your existing tubes.

2. To connect to the Manifold, Water Pump, Etc. of most Chevy and Ford engines select from the menu the appropriate NPT to -10AN Adapters. It is recommended to use a straight NPT to AN Adapter then attach your hose using your preferred angle -10AN Hose end.

3. Two methods can be used to convert the Hose Barbs of a LS pump to AN.

Method 1: Using our Barb to AN Adapters

a) Determine the correct tube size. (Most LS pumps have one 5/8" and one 3/4" barbed tube) 

b) Select from the menu 1x (5/8" to -10AN) and 1x (3/4" to -10AN) Barb to AN Adapter.

c) Simply install onto the existing barbed tubes.

Method 2: Using our NPT to AN Adapters

a) Remove the Barbed Tubes by twisting, turning, and prying them out of the pump. They are pressed in so they will come out.

This is just a suggestion only and recommend you do this with caution not to damage your pump.

b) Have an NPT to -10AN Adapter on hand to determine the depth of the tap. The holes can be tapped 3/8" NPT and 1/2" NPT. without the need to drill them.  Do not tap too deep

c) Select from the menu 1x (3/8"NPT to -10AN) and 1x (1/2" NPT to -10AN) NPT to AN Adapter.
