So I am trying to figure out what would be a good length for 3AN lines between oil filter housing for oil pressure and coolant pressure from the bottom of the thermostat housing to my Rife Triple Pressure sensor as seen in the picture below. My guess is 3-4ft for each?

 

I'd guess 2.5-3ft for Oil pressure and about 2ft for the coolant. Your best bet is to make the lines once the motor is in.

 

I see the chase bays in your bay, i thought about doing that to clean up the bay but i always see people complain they leak. Not worried about that ?

 

Not sure where it would leak other than if you put a hose off of the reservoir for the clutch master cylinder which I am putting a remote reservoir in for it so it shouldn't leak anywhere else.

 

That's the tricky part because 3AN fittings are usually brakes only and which is high pressure that means they are crimped on the lines. I may just have to do the string method then measure the string.
