Fuel system questions...

I need more fuel. I was wondering what you guys think I should do. Currently I'm running a 155 in-tank / 190 procharger in-line / 30# injectors / Adjustable FPR / Cartech Adjustable FMU. Here are my two options.

1) Upgrade to a 255 in-tank pump.
keep the 190 in-line.
Upgrade to 42# injectors
Ditch the FMU

2) Upgrade to full fuel system (pump / lines / rails)
Upgrade to 42# injectors.
Ditch the FMU.

I would like to do the first but I'm not sure that would be enough fuel. Currently the heads and intake are at the shop being ported and polished. As you can see I didn't have enough fuel to support more horsepower on that dyno run with 426 @ only 5200. What happens when I can make a full pass with the supporting fuel - prolly like 440 rwhp. So I wanna make sure I have the fuel.

Sorry for the long post.

Thanks

I would do #2. The 255l pump may be enough, but with the stock fuel lines you would be close to full capacity and wouldn't have much more room to grow. If you have the money I would do the whole fuel system and be done with it.
