Theo;

This is a concept I have not considered: are you saying that smaller 
internal diameter oil filter lines will cause a drop in oil pressure to the 
filter? or to the engine oiling system which could be seen on the oil 
pressure gauge?

I have a set of "industrial" oil line hoses on my filter set-up, and am not 
happy with my oil pressure as seen on my dash mounted gauge. I haven't 
checked the internal dia. of the hoses so I don't know if they are indeed 
smaller than they need to be, but it would be interesting if they are a 
factor in my overall oil pressure.

Thanks for this bit of info.

Dave




  If you do get oil lines made at a hydraulic shop, make sure they
 understand that this is for a continuous-flow oiling system, not for a
 hydraulic application. Hydraulic hose and fittings have smaller IDs than
 oil hose, for the same hose OD and fitting thread sizes, and you'll get
 much greater pressure loss in the lines.

  Cheers,
 Theo
