If you can't get the O-rings as Cath suggested and you have to buy a new one.....
I can't recall if they are a metric thread or NPT ( https://www.aircraftspruce.com/menus/ap/fuel_drainvalves.html) I think the latter. Take it to a Hydraulic shop and ask them to identify the thread for you. Use teflon tape or very carefully with thread sealant when you re-assemble regards Rob Rob Thompson 0429 493 828 On Sat, Dec 5, 2020 at 1:51 PM Kurt Redinbaugh <[email protected]> wrote: > The fuel drain on the underside of #3660 is weeping.
