Inliners International Forums General Discussion Engines Full Flow Oil line size?

Just finishing up rebuild on 1960-235. Had block drilled for full flow filter....3/8" NPT fittings out of block....into 8AN Russell twist-lock fittings to firewall remote filter (PH8A-type).

Was hoping that someone who was running a similar setup might might be able to offer any suggestions. I've tried to maintain the outlet ID with the 8 AN fittings....don't want to take any chance on starving this engine during inital startup. Plan to spin the pump, bleed the filter circuit, rotate the engine a couple turns by hand before adding ignition.

Any comments or concerns would sure be appreciated.

This may or may not help. I use the 3/8" pipe hole on my GMCs for the oil filters and also for external pumps when I use them. I drill the out to a size I feel comfortable with and use -10 lines and never have had an oil problem. I race these so I do not khow about street use and a -8.

Good Luck

I also used 3/8 pipe and half inch hydraulic hose years ago. I also have dual PH8A and an oversize oil pan.

Has served me well for many years.

As far as start up, don't stress, what you are planning should be fine.

You may want to find out what is best for the cam.

Dear Dave;

There's no 'bleeding' needed.

Spin the pump till you get a 30# reading on your pressure guage is all. Afer that; spin the engine (distributor in) with the plugs out a few times watching the guage.

If it 'comes up'; Your good to go!!

Good luck.

Thank you for your responses. This is new territory for me and I didn't want to take a chance on damaging my fresh engine.

Might be a good idea for someone to add to the tech tips, for the full flow filter conversion, and show some of the different mount options, their locations, and give some direction as to the materials needed to plumb the system in.

Once again, my thanks for this and the other help you've all rendered during my build.

Dave
