Default Fuel help
What is the most power that you can get before your stock fuel lines become restrictive and need to be upgraded?
Im trying to figure out if I need to go to a half in line or not.

If I remember right, sloppy mechanics went all the way to 800-900hp range on stock lines/stock truck rail before it getting to the point of fuel flow being a concern.

Thats good to know, I figured there would be more people who had pushed the limits of the fuel system than that.

On gas with meth and a return fuel system, a few have hit the 1K mark. I've gotten to 800 with a single 450 pump on stock lines.

Were you running meth on your setup? And did you start to see any hits of pressure drop at all?

Yes, I have meth. I don't have a pressure gauge, but the wideband never went lean.

Ok well it looks like I will try and stick with the stock lines then. I would like to hit 800 but Im not planning on using meth at the moment.

My math said at around 1000rwhp mark there is about a 10psi drop in pressure due to line size. Not a big deal depending where your pumps are in their curve.
