TBI to TPI swap...question on fuel pump

I just recently purchased a TPI set up off of an 89 IROC.I am taking the TBI off my 350 and putting this on after i get it cleaned up. My question is, I have the stock fuel pump from the 305 motor that was originally in the car to start with. Will this fuel pump work with the TPI set up or am i gonna have to shell out some more bucks for a new one?

You need a fuel pump for port fuel injection; your sending unit should be the same either way so... get one for a TPI car, and put it in!

TBI runs on about 12-15lbs of pressure and a TPI runs on about 42+lbs so you'll need a higher flow fuel pump. http://www.autoperformanceengineering.com/ has good deals on WalPro fuel pumps.

a delco ep-264 fuel pump is the replacement
high pressure pump you will need for the
conversion.
