According to the parts manual at http://classicbike.biz/Triumph/Parts/1960s/66Triumph650ccPartsManual.pdf
the front plunger of the oil pump is the feed to bottom end, the rear plunger is scavenge from the sump.

Oil has to travel from the strainer at the bottom of the oil tank to the feed plunger, and from the scavenge plunger to the rocker boxes and the top of the tank.

Hope that makes it clear enough.

As you face the engine from the timing side,the front pipe (closest to you) is the oil feed from the tank to the pump,pumping oil into the engine.
The rear pipe will be the return line,pumping oil back to the tank and rockers.
F=Front=Feed
R=Rear=Return This works on a unit engine,like yours;but a pre-unit is opposite.

Still check that oil returns to the tank when you start up;you can't be too careful.

ok guys, that's what i thought...and that's the way the previous owner had it plumbed (but at this point i can't "assume" anything that he did is correct after some of the things i have encountered! LOL)

anyway, thanks!
