I ordered a Racetronix pump back in 2014. Easy installation. Works just like it should!
They have an 84-85 upgrade KIT which includes pump, filter sock, rubber gasket for
pump-to-tank mount and brand new mounting bolts!

Click on " Chevy-Corvette C4 Racetronix " link and go down 5 or 6 items to the kits.
I ordered the FPA-009 upgrade. The FPA-009H has a higher 225LPH delivery volume but
the 009 has more than enough volume for a Crossfire. Remember,
fuel pressure is determined by the fuel pressure regulator, not the pump.
