What kind of mods do you have and what are you adding in the near future? You will probably be fine with a Walbro 255lp pump, stock filter and the injectors will depend on mods. You will want a Apexi SAFC if you don't have any tuning device yet.

You won't need to upgrade the fuel filter ever and you don't need to upgrade the fuel pump or injectors until you get a larger turbo. Getting more fuel doesn't add power, getting more air does and you don't need more fuel until you get a lot more air.

More boost via an MBC = more air = needing fuel mods
(this is john)

So, get an exhaust system and mbc before you worry about fuel. What is this 1g intake uprade?

BTW, I would recommend a 14b turbo upgrade soon.

It's a 2G though, the pos turbo doesn't flow crap and the stock 2G fuel pump flows a fair amount more than the stock 1G.

It would be wiser to spend your money on more basic, power-improving mods first. Do an exhaust and some sort of turbo upgrade (big t28, evo 16g) and then worry about that stuff. In addition to the fuel pump, the stock 2g MAS is better than that of a 1g, making it easier to step up to a bigger turbo more quickly.

If you want to go cheap, do a 14b or small 16g & your stock fuel system should be fine.

To answer your question directly though, if you want to do up your fuel system, you should consider:
-walbro 255
-550cc injectors
-s-afc(2)

(depending on your plans and budget)
