remove the front plug above the mack plug, split the main feed line, run the second line into the front plug.

yes, more / better pictures please. so all you need is another fitting for the front and a "T" for the line? where can those be found at?

All you will need is a T fitting that can be found anywhere fuel line is sold, 4ft of fuel line will be more than enough, some push lock fittings, metric allen wrench to remove the front plug, and another fuel fitting I used -8. I should have wrote the thread size down

here is my "T" fitting. the blue line is comming from my AD 150. The top black hose runs to where the fuel line normally feeds the ppump, the second line runs to the front plug that has been removed.

Insert your -8 fitting to the front plug, here is where the second feed line will be connected

IMO if your trying to fuel past 3500 than this dual feed will help. I also think the 160's and 175 pumps should be dual fed sooner than that

I'll be turning up to 4000-4200 maybe more but i'd rather have it and not need it than need it and not have it.

Edit: and my pump is a little bigger than a "stock" pump....
