Well, if you put a bypass filter on it would you double or tripple the ??? maybe length is not the objective? filtration vs particle size? filtration AND particle size?
Anyway, I think a bypass filter has some bearing on filtration.

I have a hydraulic filter and head (1" NPT ports, ie LOTS of flow) that is about 24" long if you ar looking for length. Never been used.
