okay here is kinda what i had in mind. Do you guys think it would support 700 hp. as long as i have sufficient pump and injectors.

 

If that's how your gonna build it with the reg out side the tank, I would not use the Corvette filter/reg, I'd just uses a regular return style reg AND boost reference it. You'll basically have a return system with a returnless fuel rail which will support quite a bit of power I believe.

 

Yea im scrapping the vette regulator idea. and The regulator im looking at is boost referenced so thats a plus. So far its looking good.

 

Your diagram is a returnless setup, except from the regulator back is in the tank. If you are intent on running this setup, I would use bigger line from the regulator to the rails. The big advantage of a return setup is not all the fuel has to flow through the regulator - only the fuel thats not used, which at WOT, isnt much.

 

The stock lines and rails will support 1000 hp or so. Now the pump/injectors is a different story

 

the regulators im looking at only have -6 input/outputs. Do you think it would still be benificial to use adapter fittings to go up to a -8 line even though the regulators only -6.

 

yes because of the higher volume of fuel in the lines, but to be honest, I think it would be a waste. Just upgrade the pump until you are ready to convert to a return system.

 

You are aware that this is going into a f150 right? im doing a 5.3 swap in it.

 

Yes. The fuel system parts dont care if they are in a leaf blower or a ZR1, much less an f150 vs a silverado. All pumps, regulators, injectors, rails, etc., work exactly the same.

 

The stock lines on the f150 are tiny. Im deff not using them. and ive already got the tank sumped and ready to run a.n fittings and line.
