Gunner .... you`re correct on extending the line an extra 10 feet . The point I was making ( maybe not that well ) is that it is best to avoid abrupt 90 degree fittings unless absolutely necessary .... and then use the gradual bend tube ones . One of the things we found was the gradual bend fittings made for a more laminar flow in the
oil and the abrupt 90`s induced a lot of turbulence .... does this make a major difference in a car`s oiling system ? Probably not , but I still avoid 90`s where possible ..... I can`t break some habits .
I`m speaking of both pressure and flow ... the delta P will increase as the flow increases . The pressure drop in the line/system will depend on line size , flow ,
oil viscosity , temperature and other factors . For a constant orifice size and viscosity , the higher the flow , the greater the delta P in the system . Again , on our systems , this isn`t a huge problem ... again , just saying that smooth bends are always preferred if you have the room .
