LUBE metering unit size ?

[D.D.Machine]

I just picked up a 2002 reman XT15 off a school with under 300 hours on it. and it has the old (NON) PDI pump on it and some smart person put PDI units on the Z axis and FJB-1 meter units on the saddle. so the Z axis has been geting no oil and the saddle is sloppy wet.

Does any one know what meter unit size this should have?

Thanks

If it has Linear Ways, uses grease, no oil. (some kind of red)
