Suppose it depend on how big your bought lubricator is, little 1" cube or 2"x2"x3" large one and what rate you have it pumping at 1 notch or several

Hello Fizzy,

If your lubricator is about 1/8" bore, generally the normal size for 31/2" and 5" gauge locomotives, then I'd use 1/8" x 26g copper tube with 1/4" x 40 fittings, quite adequate.

Regards,

Bob
