Now the T444E is a strong engine for a bus that doesent have Really BIG mountains to climb Or pull a lot of weight Greater than 74 pass bus. Mine has a 210Hp Model it has great power and doesent Vibrate as much. Around here the DTA 360 DT 408 and the DTA 466 were Very popular..
From this being a bus, are you sure you have the correct fuel pump? With most bus engines being in sideways, the engines were of a left handed variety. The fuel flow on any of the Detroits, is from the tank to the primary filter, to the fuel pump and then to the secondary filter, to the cylinder head. The only way for air to enter is before the fuel pump, as everything after is under pressure.
