99 problems and a Ford ain't one.

you have an electric pump: Put a switch on it and kill it when it starts to load up. Let it settle down (fuel bowl level will start to lower) and all will be good again IF ITS A FUEL PROBLEM. Starting fine and then it loads up tells me its a regulator problem. I fitzed with a Holley black pump and said regulator for about an hour (first I dealt with) and determined its *** backwards in what you think the adjuster does. I went the other way and it finally started to cut the fuel pressure. The guy had it all the way open and it acted just like yours but it woulld load up after about 5 minutes. If it runs good cold, Id not suspect valvetrain. A bypass system is just a T with an adjustable 'bleed' tube back to the tank. You can use your vent line if its a charcoal system (with a vented cap) or run another with low pressure fuel hose (but fuel line is easier and probably cheaper) to tank. Gonna have to rig a return spud on the tank if none available but many senderd nowadays have the extra port. I had 5 psi on my 273 at idle. enough to flicker the oil light but the owners manual said that was normal..can someone confirm? That motor had no issues. I got a cheap orifice style dial a pressure Mr Gasket regulator if you want it.
