Oh yes, I remember seeing that first pic before,...thats a nice column setup. now why did you "get nervous" about it? Buildup of fumes in the cowl? or another reason? I'd sure like to run a pressurized tank, but i'm not sure how good it would be right there on the cowl with no vent and all?? yeah, so i thought that the in and out pump WAS indeed an oil pump, but obviously the smell i got was either old oil that has ome gas in it, or, for some odd reason someone, at so,etie did in fact use it as a fuel pump somehow??
