This whole Tu-Flo 700 discussion (here and on my for sale listing: http://www.busconversions.com/bbs/index.php?topic=17270.0
) has me confused (not a hard thing to do
I just went out an looked at mine again, and it has the oil supply plumbed into the end cap at what looks like the center line of the crank. There is no return line. It looks like the oil is returned via the gear drive opening in the block. If that is the case, is there a notch in the compressor housing that controls the level of the oil in the compressor? If there is a notch, can a new notch be ground for something other than vertical mount position on an Eagle?
