Hi Guys,

Has any one info on what the limits are for the factory fuel feed lines are for evo 8?
I found out that they are 5/16" (7,9mm). How much max bhp can be run before putting larger lines?

Thanks for info

Your question is in regards to fuel flow & not fuel line construction? Correct?

What type of fuel pump are you or plan or running. Pwr levels below 600whp, I doubt any fuel line consideration is needed. I can see a fuel rail change at those high WHP no.s

Heres a good thread discussing the topic

Yes, I plan to run the walbro 400 or aeromotive 340 lph (with hardwire) for my 500whp build. I believe it should be enough.
therefore my question. I assume I do not need to run larger fuel lines. Fuelrail is Magnus, ID1000 etc..
thanks for the link

The stock line is basically the size of a -6an line. You're fine with that for quite a bit of power. Buschur is running their double pumpers to that hardline and has plenty of fuel for 700whp.
