Fuel Pressure Problems March 01, 2009, 05:33:01 PM I Have A Problem With My T-bird's Fuel Pressure Falling At Acceration From 40 Lbs To 25. Is This Strictly A Fuel Pump Problem... Or Could It Be The Fuel Pressure Relay, Faulty Tank Gaskets Or Something Else Causing This Problem ? I Know It Has A Aftermarket Pump In It.... Probably A Cheap One. Any Help Would Be Greatly Appreciated..... Quote Selected

One TC I had the pump wouldn't make more than 25psi dead ended, and the guy wondered why it wouldn't run worth a ...BTW at TC should have 55psi at full boost... Quote Selected
