Is my Fuel Pump large enough?

I am running a Holley 255lph in-line pump on my car.
It will have an LT4 with a 150-200hp Fogger setup.
Just want to know if I will need to add another fuel pump.
Here is the Kit I have,

id say run another electric pump i guess u could call it inline. but just acctach another pump to the fuel line close to the engine or engine bay so that it would keep the fuel pressure thats coming out of the pump in the tank. im not to sure about this. i know someone else knows but im just taking a stab at it.

My fuel pump on my car right now is an external in-line pump.

You can always put in another inline. It's not impossible

possible but is it advisable/necessary for maintaining the pressure? i mean i know these cars are long ( try shimmying under one with no roller-pad to slide ... i swear it's a mile from the front bumper to where the shifter-cable bolts to the gear selector on the 700r4 ) but can they lose that much pressure between the pump and the heads ?

One alternative would be to add a second pump and hook it directly to the NOS Fuel Solenoids so that they get thier own fuel supply. That should work, right?

Yes. I know a guy that has a separate 5gal cell he fills w/ cam2. He run 93 in his gas tank. There's a separate line going from the cell to the fuel solenoids.

Yep, that is teflon tape and it is coming off. A friend told me saturday to use teflon paste or something like that since the tape can clog or make the solenoids stick open.

Oh, and the tape was on it when I got it. It wasn't ran with the tape on the solenoids, so I should be fine once I remove the tape.

teflon paste is good, very good. Unless you use too much and use it where no sealant is needed like this dip I took pictures of did.
