I think I'm still running the stock fuel pump on my car.
Do you guys running modded Nikki,s upgrade the fuel pump?

 

You will need a better than stock FP for a heavily modded nikki. Depends on how much you modded it. The stock pump is just enough for a stock nikki. Mind you will need to make sure it still only pushes about 2.5 psi, its all about how much it flows in GPH.
