I'm thinking of doing dual intank fuels pump along with maybe 10AN steel braided line. A little overkill but I have an extra 255l pump and I don't want to have to touch the tank again. Do you think 2 pumps is too much current for the stock wiring if I just tap it or do I need to run additional wire? It'd probably be about 20 amps total. Has anyone already done this?

 

If you are going to go thru the trouble of upgrading to two pumps and a new line, I would definately put in a hotwire kit. I am thinking of doing a hotwire kit with just my single 255 pump.
