If you have an electric fuel pump it should be connected before the racor. Suck directly from the tank and as close to the tank as possible, discharge into the racor. This eliminates the chance of a vacuum leak in the racor or anywhere else downstream of the pump since down stream is pressurized.Our era of boats were typically equipped with 200FG model racors. Glass/plastic or metal bowl for diesel. Metal bowl only for gasoline. I found venting to be a PIA. I've shared this before but here is a video that includes a mod for easier venting. This mod requires drilling and tapping the racor head.https://youtu.be/H-GI38vE4hQJosh MuckleyS/V Sea Hawk 1989 C&C 37+Solomons, MDOn Thu, Sep 23, 2021, 10:14 David Knecht via CnC-List <cnc-list@cnc-list.com> wrote:Sorry if the start of the thread was lost somewhere. Quick summary: The problem was the engine twice ran for some time and then died and would not start. When I checked the Racor later, it was half full of fuel so diagnosis was either electric fuel pump not working, plugged pickup tube or vacuum leak somewhere so it could not pull fuel from tank. I have been chasing those down and now confident the pump and pickup are working, and vacuum leak is either in fuel line or Racor holder. That is why I decided to replace fuel lines when several listers suggested that as most likely culprit (from past experience with the same problem). Dave S/V Aries1990 C&C 34+New London, CT

Why are you chasing a fuel pump issue? Do you have a no-start? A boat dying after a certain amount of time?

If you are referring to a schematic the ground wire may not be illustrated.
