My gearbox pump (Moroso unit) does not stand up to the pressures and temps
seen in my RD-1A installation. I have been unable to locate a better pump.

I am almost ready to give up my custom oil system, and connect the engine oil to the PSRU, as Tracy Crook recommends.

Has anyone connected the oil drain without removing the oil pan?
