what is the advantage to oversized injection lines and tubes?

 

On a street driven truck - none

 

so where does it help the truck

---AutoMerged DoublePost---

there has to be some advantage to these lines or they wouldn't make them

 

they make them for the really hot pulling trucks, that need a lot of fuel.

 

i have .120 fuel lines on my p pump 24v and there is no advantage to having them on the street. When i run the track it provides all the fuel i need with minimal restriction though, u cant tell any difference on the road other than fuel mileage
