Default Walbro 450LPH E85 pump in a 98?
What all will I need to do if anything for it to fit?
Looked through the walbro thread and didnt see anything referring to that pump. I was watching a local shop trying to put a 400lph in a gran prix gtp's bucket and it definitely didnt fit like a 255 or a stocker would.

My goal is 600whp this pump should support that I believe. Though unsure if I will also need to upgrade the fuel line as well.

Why not just do the 2 255's?
My car made 543 565 on 1 255 on 10lbs of boost. Still had plenty of fuel too.

Why buy 2 pumps when I can just buy one?

Good to know on the buckets. Ive yet to rip this car apart so unsure of differences in the 98. Walbro lists 2 450's I believe one for E85 and one for regular gasoline.

I was assuming you had a 255 in it already

To my knowledge the previous owner never dropped the tank. Though honestly who knows considering the amount of work he did on the car.

Gotcha, my car has 1 255 in it now. Going to add another and run E85 and turn it up a bit once I get a rear end.

What about in a 2002? Is it not a direct replacement for a single 255? Will that flow enough for 650 rwhp? (No BRFPR)
