my car has a new zz4 installed by previous owner, but i noticed that the fuel pump looks old, and given the fact that the fuel line going to the pump is very old and cracked (yea, i know, replace it), my guess is the man essentially took the l48 fuel system and put it on the zz4.
so, should i switch this part out as part of a high performance engine???? the fuel lines coming from the pump to the carb are braided and new.
also, noticed the return line to the fuel tank is capped. is there no way to use the return fuel line?? the car is equipped with an edelbrock.
