HOOKING up Spin-On Notes: spin-on have 2 outlets. Hook one outlet(running engine) to the outlet of the second engine spin-on. All examples displayed using aluminum fittings except 3/4-16. "SAE" signifies straight thread, not "NPT" which is tapered. Running two engines off one filter probably means they can't run full throttle.

Hooking up Spin-On 400-600/120 size TOGETHER, uses 3/4-16 SAE

Hooking up Spin-On 400-600/45,60,90 sizes Together uses 3/8-18 NPTF

Hooking up Spin-On 220, 225, 230, 245 sizes Together uses 1/4-18 NPTF

Pumping FROM Spin-On 200, 400/600, 400/600-120, uses 1/4-18, 3/8-18, 3/4-16 into jug

Notes: "AN" parts #6 equals 9/16" UNF(SAE), Pictures to Follow

AN = Army/Navy, OD = Metal Tube

  3/8-24, 9/16-18, 3/4-16, 7/8-14 are all fine thread (bolt) sizes. Also known as UNF or SAE

-3 AN = 3/16" OD Tube, 3/8-24 SAE

-4 AN = 1/4" OD Tube, 7/16" - 20 SAE(not used by Racor)

-6 AN = 3/8" OD Tube, 9/16"-18 SAE

-8 AN = 1/2" OD Tube, 3/4"- 16 SAE

-10 AN = 5/8" Tube,  7/8"-14 SAE
