Fuels lines - 3/8" or 1/2" ???

[GOT-Torque]

Is there any reason to need 1/2" fuel supply lines on a 3rd gen truck? I'm going to be using the glacier diesel pump setup and I noticed it comes with the 3/8" fittings and lines. Is there a certain hp level that requires bigger lines than 3/8"?



Current plans for power are TST powermax R49, SPS62 turbo, and upgraded intake and exhaust.



Thanks!

Still running the 3/8" lines on mine for now.

3/8" is big enough, but bigger is better right?

the line i am going to use is setup for 1/2" fittings, but the line is actually 13/32" inside [1250psi rated hydraulic line]

I have 1/2 inch all the way from tank to injection pump from Vulcan performance. I just wanted the peace of mind of knowing I had the extra volume capacity. Can't really say it made more power.

I ran #8 line from the tank to filter and #6 to the CP3, maybe one day I will really need it. :-laf There are some pictures of the install on my site, in the video section.
