Which metering fitting goes where?

I have a BMC-20 machine and just cleaned up the autoluber and didn't notice which fitting went toward the head and which went toward the table in the tee block that is fed from the autoluber unit. I have a FJB-3 and a FJB-4 for fittings. This is just the start of my cleanup. The "Y" ways are pretty dry and I am thinking of removing the table from the machine to clean out the grooves. I have read most of the posts on lubing this machine and will be using the info as I progress. Thanks for any info.

Just talked to Steve at Hurco and he mentioned the 3 goes toward the head and the 4 goes toward the table.

I am trying to remove the lid to the lube motor to tighten the motor housing back down to the tank lid. My problem is there is no visible means of holding this lid to the motor housing. I tried gently prying on it but because the housing is loose on the tank lid I didn't put a lot of effort in to it. Any body familiar with this?
Thanks,
Steve
