Is there a company out there that makes over size fuel lines for the vp pump?(from injection pump to injectors) Just wondering if anyone has seen them. I know you can put a big line kit on with a air dog but i was wondering if the injection lines or tubes were worth looking into or if they even existed.
Let me know what you guys think.

 

They exist but are pretty usless unless you have a all out compition engine.

 

Yes there are bigger lines.Most use these bigger lines for truck pulls or very extreme VP44 trucks with Compounds,big injectors and alot of NOS.

 

You probably wont like the way it runs if you put those big lines on a stock, or midly modified engine.

 

If you go with just a set of .120 lines it wont even idle...

 

Been there what a nightmare..

Some customers don't here me when I talk.

 

so basically if your not on a 1,000hp quest they are useless, got it. So are these lines what make the engine lope real hard at idle? Thus the reason for not idleing?

 

yes they are useless even on a 700hp truck. they don't gain a thing. stock is best.

 

100% agree
