premix vs oil injection

Hey everyone I got a 2000 gti and Im thinking about deleting the oil injection and yes I would rather the motor be safe. I know you have to cap the pump and the injection inlets but i was wondering about the 1/2 inch tube that comes out the bottom of the motor back to the oil tank can i just cap...

Hi so i have a 95 xp, i want to do something with the oil injection pump because iv read on here they are not reliable. Should i replace it with a new pump or should i just get a block off kit and run premix? also how hard is it the replace it or do the block off kit? what are the pros and cons...
