Bigger fuel line

[6speedsd]

Is it worth running bigger fuel lines from the filter to the heads with stock injectors? Have the truck torn down and was looking over things and started thinking about replacing the hard lines with braided a little bigger and some AN fittings. But wasn't sure if there was a benefit to it with stock fuel, or if a set of 6.4 banjos with stock lines would be plenty.

I wouldnt... Now Im about to remove my secondary fuel filter/bowl from my truck and run mine into the heads directly.. I do have a Strictly Diesel RR that uses their own custom HUGE fuel lines into the heads and their own banjo bolts. That may be a decent upgrade as its a bottle neck. So if you're interested LMK as I plan on selling them...

Here you can see the size difference.

You wont notice anything either way. The banjos are definitely the biggest restriction currently though, so replacing lines with larger line without touching those will do nothing at all.

So just slap on a set of 6.4 banjos and call it a day?

If you feel like it, there's not really any proven info that the 6.4 banjos do anything either. Maybe if you were feeding larger injectors it may help, but on a stock truck not really any point, IMO. It certainly wont hurt to do, it is the biggest restriction and the cost is minimal to upgrade.

Just always heard those banjos were less restrictive than stock 6.0 banjos. Why I mentioned putting a set on there. And like you said...Roughly $10 in parts...cheap upgrade if you want to call it that.
