Custom oil line, how long?

[Dan!]

I cant see the block fitting be that obscure, plenty of people seem to have done this now and iv never heard of it being a problem before :think:

Also, re compression fittings:

They should be used in applications where the fitting will not be disturbed and not subjected to flexing or bending.

Bolted to the back of an engine? :o

Im not saying your wrong Mark, I just think the other way will be easier and id like to know how long it needs to be.
