What size fuel supply line should I run from my tank to the draw side of my belt drive Aviad pump. 540 Light pro diesel |

#12 minimum, or better yet, #16. If you draw a vacuum on diesel fuel, it aerates. Air will compress (fuel won't) and will mess up your injection. |

You mean air can actually be drawn into the fuel and cause like a cavitation in the system?? |

We run everything in #12 or 3/4.
Be sure to put a ball valve close to your tank outlet so that you can take the system apart for service. Chris Watson Watson Motorsports Batavia, OH |

What size line from the Aviad to the injection pump. Is 60 psi enough fuel pressure? |

If you run dual feed to pump, minimum of # 8. 60 psi is good. Don't need more than that if it holds 50 psi going down the track. Volume is just as important as pressure--or more important. If you calculate the amount of time that a pump plunger has to be filled with fuel, you will understand why volume is important. |
