if i put one of these on my car would i need to upgrade the fuel lines to handle the "high pressure"?

 

nope

 

Why would you need one anyway?

 

for the turbo swap. i know i'll probably never need the amount of gas it can push but the price difference for it and the regular 255 is only about 10 dollars. i'd rather not take the chance of actually needing it (if i do try pulling some serious power) and spending 200 dollars
