The one DLS sells looks like that, I believe the white racing does too. I dont think the White Racing cover has an external pressure reliefe hose, it does it internally.
The picture I posted of my alum engine with a Dut pump is over 12 years old, and even years before then I have worked with Kenny and his engines, and have never seen the hose fittings on the bottom side of the pump.
Maybe he did a one-of, but it is never shown in his pump documentation that I have, but it could be possible?
