My L03's gonna go as soon as i get the LT1 pieced together, and I'm trying to plan out the details. I've heard it's a royal bi*ch to change fuel pumps, so is there a way that I can just add another inline fuel pump to my existing TBI fuel system? Or do I need to drop the tank and swap in a TPI/LT1 fuel pump?

 

Drop the tank. You car is old enough where it would do you a world of good to take the tank out to make sure nothing is rusted.
