I have a 507 and do not use an inline oiler....but you will definately need a filter on the outlet.....I have 12 gallons of reserve tanks and it takes like 30 seconds max to refill them from like 90 psi to 155......the 708 should be way faster....and if it has the oiling nut on top it is a wet sump......As for line I tapped mine out and use 3/8 fittings with 1/2 inch line to the filter, then it goes to a check valve, then out to the system thru 2 3/8 inch nylon airbrake lines....but those are gonna get tossed in favour of some hydraulic hose.
