I need to re-route the pipe running between the oil tank and my 50kW

pipe run info for 10mm (O/D) and I haven't been able to find any other
info. Any suggestions on where to find further info or how to do the
sums on the effect of a few (6 or 8) 6mm restrictions in an 8.6mm bore?



Would the use of flared fittings avoid the loss of flow induce by a pipe
insert? I guess youd need a flaring tool but you cant have too many
tools. ;-)

It would, and that had been Plan A, but I'd discounted it because one of
the points (the end of the existing pipe) would be impossible to get to
with a flaring tool ... and I don't have a flaring tool
