At what point do the stock fuel rails need to be replaced? Not from being worn out but because of the mods you have done. I don't know but I can't believe new ones are that much better than the original ones but tell me if I am wrong.

Figure if I am in there doing injectors again might as well do the fuel rail if it needs to be done.

Thanks,

Im pushing about 500rwhp on stock rails with no problems

 

I believe Parish made 1K rwhp with stock rails and lines.

 

he also had fuel pressure spikes at higher rpm i believe

 

more just to look good than actually work better.
