I am geting rid of my V6 carb in favor of a tpi set up and have a few questions if someone could help. I am using a 1990 camaro speed density 305 and I am not sure which fuel line is the return and which is the feed. Also can I just not hook up the pollution pump, egr, and purge canister without getting a check engine light or does the prom have to be reprogrammed. Next is how do i take the pollution pump off pf the serpentine system and still keep the A.C, power steering and of course alternator and water pump. Thanks for the help

 

I'm pretty sure by '90 that motor had a serpentine belt system, so all you have to do is buy a smaller belt and presto.

And you are going to want a different fuel tank to go from carb to FI. TPI's use in-tank fuel pumps.

 

in order to delete the EGR youll have to buy or make a egr block-off plate. When you do that you'll have to take the EGR solenoid vacumm line and plug it. That will keep your ses light from coming on. If you move all the a.i.r. equipment you would be in best intrest to get a set of headers.

 

Why?

 

so you dont have the little egr ports coming out of the stock manifold. Is there something i need to know about?

 

Fill the AIR tubes with plugs. No leaks and it only costs about $4.
