I am going to swap the tpi for a carb on my vette motor. Should I run a pressure regulator between my existing in tank fuel pump to the new carb setup? Should I just pull the intank pump and run a rail pump like a walbro or holley? If so, is it hard to get the fuel tank out of an 86 iroc z with the rear end being directly under it?

 

I have an 86 also and I will say those tanks are a pain to get out if your doing it by yourself. I would just go buy a Mallory 3 port regulator and put on it on. Make sure you regulate the fuel pressure to about 61/2 to 71/2 pounds before you start the engine.
