I run a big pump on the longhorn(72psi @2500). I have a stock 1 ton truck pan(6Q pan),& run 20/50 penz. I dont have any trouble with sucking the pan dry,but dont romp it till the oil is completely warmed up. You might try a little thinner oil,but it sounds like the pan isnt big enough for the oil pump. Do you have the # on the pump by chance?
