Re: Tbi swap build thread

Do you have any rubber fuel lines in the system?

I have seen them work fine when cold but kink when they warmed up. Makes for some interesting trouble shooting.

Is your pump in the tank or in-line? It could be a loose connection between the pump and the supply line to the TB at the pickup if it is in-tank. It is a rubber hose and could be losing its prime through the leak and/or losing pressure through the leak and gets worse as the pump heats up.

Just some thoughts based on problems I have encountered.
