Default In-line or in-tank fuel pump????

I need to do a bit of fuel system upgrading for a nitrous kit I bought. I'm not sure if I should go with a higher volume in-tank pump or an in-line pump in tandem with my stock pump. Can anyone offer me any advice? If I go with the in-tank I will use the Walbro kit. If I go with an in-line pump I will use the Accel #74702 kit. Can anyone recommend anything else?

I don't know if a single in-tank pump will be able to supply enough volume. My engine is basically identical to yours with the exception of ported Edelbrock heads rather than Track 1's and the blower. I'm hoping to run a 100hp shot on my NX system and I don't want to burn my pistons down due to running lean.

We generally like to do an aeromotive pump inline and replace the stock in tank unit with a pickup. The aeromotive mounts very nicely behind the license plate.

That is more fuel pump than you need for your setup though, but generally it's better to have too much than too little fuel.
