Pump head 3/8" FPT filter port and 3/8" outlet port
Specifications
This head has 3/8" FPT threaded ports on both sides. If your head has a 3/8" port 90° from the air filter, you will need to take a 9/16" drill bit, predrill and then a 3/8" pipe tap (if your head has 3/8" outlet) to tap the hole for your unit. Simply take a 3/8" plug and plug up the unused hole. You may also have to file down two tabs underneath the Head.
Do NOT order this if you head looks like this below with 2 holes on the SAME side of the head.
