All the splash-oilers have those tubes. The important thing is to get them targeted right while the pan is off. Draws an "X" with a sharp-pointed scribe straight across from each squirt nozzle, attach a garden hose to the supply tube, and bend the tubes until the stream of water hits the center of the X. At speeds above idle, the oil squirts directly into the dipper instead of picking it up out of the trough. There was once a fixture for setting the squirt tube alignment, but they're scarce and expensive now if they can be found at all. BTW, the alignment dimensions for the troughs and the dippers are different for 216 and 235 rods and oil pans. Splash-oil 235 pans will have a big "235" stamped into the side of the pan. The difference is the stroke- - - -a 216 pan on a 235 engine will end up with the rod dippers hitting the troughs.
