[Tiara Open] 454 shutdown

[Robert]

This is a long shot: My 1995 454 with fuel injection would not hold rpms and eventually cut out mysteriously - mechanic first thought electrical and then fuel. After trying many fixes - and throwing a ridiculous amount of money at the problem - it turned out to be a defective anti-siphon valve in the fuel tank that prevented fuel from being drawn from the tank.
