Inlet and outlet size of pipe on tank

[24OZ]

Hi all,

 

I have a 240Z and i have a turbo engine fitted. Currently having my tank adapted to an efi tank.

 

I have told the shop to make the inlet pipe (fuel return) on the tank an 8mm and the outlet 15mm.

 

Do you think the size i have specified for the return is too small? I am aiming for around 300hp.

 

Any ideas of how much hp, that will be good for?

 

Thanks.

I did not mean to imply that 8 mm (~5/16") was insufficient for your purposes. Most people, who do not modify their tanks, run the stock 5/16-in. old feed line as their new return.

 

I only asked since you are having a shop modify your tank. There is nothing wrong with a 5/16-in. return line. I personally opted for 3/8-in. feed and return. I am also running all new 3/8-in. hoses for both my feed and return.

 

I am assuming that you are going to use your old 5/16-in. feed line from the engine bay to the tank as your new return. The return inlet will not be your restriction, it will be your hardlines. However, you will be fine.

I have run a new 3/8" copper/nickel hard supply line and I am using the old 5/16" Supply as my new return.

 

Thanks for the confirmation KTM. Fueling has never been something that i pondered about greatly, learning loads from you guys.
