Hi my name is***** will be glad to help. So there is absolutely no trouble running this out of a bucket. If that is the case double check the new lines for restrictions in case one has some debris or a rubber flap restricting the hose from the fabrication process. If okay, check the tank vent and your return/supply to be sure none have restrictions or leaks. Try running the fuel lines into the fuel fill of the tanks and see if it will pick up that way confirming the fuel lines are good and there is a problem in the tank pickup tube or a restricted fitting or venting issue. Let me know
Thanks for the update. If no air on the suction side viewing with a clear hose or sight glass but air on the return it points to injectors, o rings and cups. Is the return fuel turning black with soot? If so it is a sign compression is being forced past the injector and then getting into the return. Id pull the injectors and take a look at the o rings and cup condition. It may be just failed o rings. But is could be a failed injector as well. Have your local injection shop test them. Let me know
Any clear hose adapted inline will serve as a sight glass from your local hardware store.
That is fine. We can follow up as needed.
That is a possibility. Try to block that off and recheck for bubbles to confirm.
