I am pulling my engines out before the season and wanted to install a oil drain system from the drain plug on the Pan. (Not go through the dip stick anymore) Does anyone know the size of the threads of that fitting. ??? I think Merc makes a fitting with hoses doing the same for other engines.?? Does anyone know the part number and if the fitting wpuld be the same on my 502 Pan.
Thanks in Advance

they are metric now, not sure when they switched, when I installed the new GM vortec big blocks I had to tap the plug threads back to american so I could reuse my crusader either side dipsticks..Rob
