Here is an issue I am having..when the engine is running in the 36 the fuel pump glass bowl will have an off & on surge of large air bubbles.
I suspect that the fuel pump is sucking air into the system, the pump is a new repro from a Ford vendor.... I have double tightened all fittings including the screws on the top fuel pump cover.
Nothing is leaking and the car seems to be running well...I have never run across an issue like this.
Anyone ever have this type of situation ??
Could it be something internally in the fuel pump ???
