Well I have a 98 GT that is hopefully with nitrous be well over 320+RWHP I have seen that the stock pump only supports 300HP and the pump and fuel system are bastard on the 98's so if anyone has a 98 with an aftermarket pump please let me know what you did. THANKS!
I had a KB boost-a-pump for awhile, but I upgraded from that recently. Sumped tank, aeromotive a1000 pump, 10-an supply lines to new rails, new regulator and 6-an return. Overkill for sure, but it works good.
