Bus was running very sluggish did a few checks And found the fuel pressure is at zero psi it just blurb fuel out while the engine is running I understand it it should be at least 10 psi at Idle and up to 60 at 1200 RPM anybody know the part number so I can order a new one
That is a gear driven pump, they usually work or don''t work. Make sure all other lines are OK before you replace pump. Check eBay you may find one there.

According to the parts book I have the fuel pump type 174 ( std) is 5199560 overhaul kit # is 5195078
It should be 5108064 for the standard pump, I use the 5108067 high capacity pump to replace all the fuel pumps on the 92 series mechanical engines. if your engine is a DDEC it takes a different pump.The LH or RH stamp on the pump is for the suction location fwiw so match those
I'm pretty sure it is a ddec engine it has a computer sitting on the top and it is flyby wire I assume that means it is ddec what's that part number ? Standing at the back of the bus the fuel pump is on the left side of the engine behind the crossover tube is that a right-hand or left-hand ? Thanks
