should i see oil going up the lines? honestly, the lines look clear...i couldn't tell for sure, cause it was dusk, but i was wondering if there's an easy way to tell if it's working right

factory test is to pull a line off, and measure what comes out...

pull it out up by where it injects? that seems really tough to do



edit: oh yea, how quick will they take to fill if they were empty? (since i had them disconnected from the omp for so long)

hmmm...im really beginning to wonder if it's malfunctioning, perhaps it's clogged? is it easy to pull off? if i pull it off, do i need to empty the oil (will it start draining out?)

that test was easier on the older ones, these newer ones are kinda lame. id pull a line off the metering pump, and see what comes out
