It's no where near plug and play, you have to do alot of modifications and you have to Dremel the bottom of your intake manifold. Imo I wouldn't cheap out on an hpfp. There are better places to save money like intakes and downpipes.

You should do alot more research on hpfps before deciding which route to go.
Hard to swallow $1,300 for a fuel pump when I have no plans to upgrade the turbo or run E. Absolutely silly.
