If you have a J5A with the 25 gallon fuel system with a 7 gallon header tank and a 18 gallon wing tank this is for you. The fuel supply line from the right(only one) wing tank should be placed as in the Piper manual and in my pictures to ensure good fuel flow.
Some restorers run this fuel line from the right wing tank over entry door then down frame tube to the header tank. It actually needs to be plumbed thru the forward top of door to get the proper angle. From personal experience when adding fuel into a totally empty fuel system no fuel flowed from carb fuel line until 6 gallons had been added with the over door routing of fuel line. When it was relocated as in picture fuel flowed after 1 gallon. I have enclosed pictures of the correct fuel line routing to prevent this.
