New guy here ,
I just picked up a 95 sc400 it's been sitting for a year or two because of a bad fuel pump.
I ordered a walbro 225 pump still waiting for it to arrive.
I'm going to do the 12v mod I've checked my ECU and everything is fine.
My question is since my tank is garnishvarnished up and I'm replacing the pump and filter I'd like to upgrade my fuel line and return line with braided line that's a bit bigger .
would anyone be able to point me in the right direction?
Yes I've searched here and used Google I searched fuel line upgrades

 

There will be no gains at all with a bigger fuel line. If it isnīt damaged, donīt change it.

 

it is damaged its leaking in about 3 different places

 

Unless your planning on turbo / supercharging the engine there is no benefit. It may actually over work the small fuel pump trying to
fill / pressurize the larger line.
