Doing just .093 tubes shouldn't hurt anything. However, if you were to run .093 lines you would have a serious lack of streetability as the truck would constantly want to die.Just got done installing a lightning vp pump from scheid on a 2001 stock injectors,lines and crossover tube. Motor is being fed by a fass 150 pump. At idle the truck has white smoke not much but you can see it and smell it but the smoke goes away when the rpm's are raised. Is this normal for the pump?? I have no air in the lines. I am going to pull the injectors to have them tested just to make sure they are ok if it is not normal for the pump to smoke... Also with this truck being a auto will it hurt anything going to .093 tubes??
