I need to add two return lines in my polyethylene cell. One for the bypass on the pump and another from the nitrous regs. Where is the best place to drill the fittings in at? Any techniques to keep junk out of the cell?

dont use a hole saw, use a step drill bit, going in as tight as possible so you get a snug fit.
you can go in a little at a time to get proper fitment.

Drill bits and step drills tend to grab,wooble and tear at the plastic fuel cells,especially when your trying to make a large hole for a #8 balkhead fitting.IF your hole is a little loose just use teflon washers which are recommended for both sides of the fitting. 
sorry but i disagree totally. using a step bit goes in like butter and bulhead goes in nice and tight with a teflon washer.
the jaz bulkheads are the best by far. 
a hole saw gives you a ragged edge and i havent liked the holesaw fit, it seems to be too loose.

x2 i agree with SUPERSTOCKRACER,i used a step bit and it cut through with no effort and didn't damage the cell

a step drill bit works like a charm. only needed one bit to do every size hole up to the 10AN to feed the pump.

 once you go too big your done and no going back, i put duct tape under the area where you drill to catch the shavings and then took a plastic bag and opened it up inside the fuel cell to catch the remaining shavings, i also removed the foam and then vacuumed out any remaining shavings with a shop vac.

If your going to vacuum it out no need to do all the tape and bag stuff.
it's ok to butt heads, just don't do it with a butthead

Yup, step drill, rag under area, shop vac, remove filler neck and make sure you can reach where you are putting the hole.
