hp rating on fuel rail and lines ?
i've got an engine being built it should be around 750 hp (flywheel) will the stock fuel lines handle that ? and if i did a racetronics kit will that supply enough fuel ? or should i sump it with an external ?i will be going away from the fmu and the pcm will be set for the charger ! my car will have a golen 383 with a p1sc (twin intercooled) if that doesn't give me enough power to get 750hp i'll upgrade it to a d1sc ! i was told it will hold up ! but you guys might know otherwise ! the engine is the 480 hp 383 with a few extras set up for a blower lloyd elliot heads (lt4) with a ported lt4 intake bbk 58mm throttlebody custom blower cam longtubes with 3" true duals ! 4.10 out back and either a 3speed auto or a built 4 speed auto !

I run 800 flywheel with dry nitrous, through -6AN supply and return lines, which is the same diameter as the stock supply line and only slightly larger than the stock return line. Should be OK. On the rails, I "split" them so they have an inlet on the back of each one, and a single return connection welded to the crossover pipe in the front. That puts them in parallel, rather than in series, increasing the capacity. Probably good for up to 1000HP.

My buddies car made 487 RWHP NA, then it took a 100 shot fine. The 150 shot we lost fuel pressure on it. So thats roughly 650 rwhp
That was with a huge inline pump and stock lines/rail.

Drivers side rear of rail. There's a -6AN from the tank, that splits in front of the fire wall using an NOS-6AN "Y" into a -6AN into a fitting welded into the back end of each rail. You also see the return line in the top of the photo, going to a Weldon AFPR mounted under the cowl. (Ignore the braided line on the center/bottom background.... that's the tranny dipstick):
Passenger side rear fuel rail, with feed line and fuel pressure sensor tap on rail:
-6AN connection for return line to front crossover line:
Return line from crossover rail to AFPR under cowl:
