PMO fuel pressure regulator. With the barbed nipples it is 8mm for all of them including the one for the stock size 9.5mm supply line. The AN6 fittings are 9.5. How did you get around this? This one has 8mm supply feeding two 8mm nipples to the carbs. Am I missing something, do they all need to be one size? I ve been all over town trying to find a 9.5 barbed fitting with no luck. I’d call PMO but I could only find a fax number. A little help would be great. Thanks

Thanks From what I understand, 5/16" = 8mm and 3/8" = 9.5mm UPDATE: Amazon has the correct unions for a better reduction. Perhaps the inlet can be had as well. What's the threaded size of the inlet barb fitting? |

I have some good pipe dope for the threads |
