Message	Replaced fuel pump hose in tank that commonly splits. I'm not sure where the fuel is going and it has driven me crazy. Greg said not to worry about it but it really bugs me (and is probably related). My old Z held pressure indefinitely. Any ideas I am all ears! I've heard rumors of some check valve but I haven't found it. Almost replaced the pump last summer, but when running the car's fuel pressures is right on. I tested injectors in rails very thoroughly before installing plenum...unless there is only a leak when it is hot? '91 TT
