    here is a good way to know 100%   if you need to replace seals..  about a 40$ investment on Amazon .

    8MILELAKE 21PC Hand Held Vacuum Pressure Pump Tester Kit Brake Fluid Bleeder Bleeding Kit, Brake System Bleeding Tools – Amazon Canada

    the pump does not come with  the  3/8 16tpi  thread adapter so look for a oil pump kit like the video shows.  you  can use it to pump your oil  and…. supply the pressure adapter with the necessary thread adapter to pressurize the GC.

    you can also to  a VACUM test to confirm the seals work both ways !

    my 75hp was  tested perfect yet water got in one season …   now I always use new nylons under the bolts   !!
