What size are my quick disconnects??

[perry]

I usually pick them up myself from the parts tray at NAPA, found a pretty good deal online and they offer many sizes #8 #10 #12 and so on.
I have a 853 with original quick disconnects.

Thanks

Provided that your tube lines are 5/8" O/D, you will need #10.

Provided that your tube lines are 5/8" O/D, you will need #10.

The coupler end is either 1/2" "Pioneer" if its the old style, female has a cavity or open center
or 1/2" "faster" if its the flat style.
As for the back end I think my 853 had a #12 (which is 12 one 16ths of a inch, or 3/4")
A number 12 takes a 1 1/4" wrench to loosen the female JIC nut
#10 is 1" on the female
#8 is 7/8" on the female
