Ok, does anybody know when the stock lines and crossover give up? Im not talking about the pump, regulator, and injectors, just the rest of the stock setup. I guess Im asking what kind of power is needed to require aftermarket lines and fittings be welded on the rails?

Need year of car and engine type to answer the question.Fred

The stock lines will easilly support 800HP, the rails, with minor mods have been shown to support over 1,100HP. My setup, supplying a 381 stroker that make 500HP on motor and runs a 300-shot of nitrous (0.53 BSFC @ peak torque):
-Bosch 205 LPH pump in stock in-tank position (all that is needed for 500HP)
-Bosch 205 LPH pump pulling from a sump on the bottom/back of stock tank (only runs when the nitrous is armed).
-Pumps each discharge to a -6AN line that joins in a "Y" and then flow through a single -6AN line (equivalent to the stock 3/8" lines) to an SX billet filter in the stock position.
--6AN forward to the engine compartment, coming up behind the engine, splitting through another NOS "Y" fitting, with -6AN lines into the back of each stock rail.
--6AN connection welded to the cross-over pipe at the front of the rails, with a -6AN line back to a Weldon AFPR under the cowl.
--6AN return line all the way back to the tank. (slightly larger than the stock 5/16" return)
The system supplies 58psi to 78# injectors. There is a tap on one rail for the fuel pressure sensor.
A similar system has been used on a couple of 1,000+HP blown LT1 engines the same shop built, except that they pull a return connection off the front of each of the rails at the 1,000HP level.
The weak point in the stock system is the fuel pump.... probably good for 400-450 flywheelHP. But there are low $$$ upgrades available. Stock lines and unmodified rails should be fine up to 750HP.Fred
