I had a 1981 Volvo (in 2003). It had a B21 engine and a 4 speed + OD standard transmission. I daily drove it and it was fine. The Bosch fuel injection was very complicated, and when the fuel pump went, I happily changed the tank fuel pump, not realizing there was another fuel pump mounted under the drivers door.

Pros: interior was very high quality
Cons: fuel injection complicated
Vehicle: Volvo

I learned that when my generic $125 fuel pump turned into a $750 tow and a $150 U-Haul trailer rental and 3 hours on the side of the road waiting for U-Haul to fix their blown out trailer tire. And then a new $400 Bosch fuel pump that I should have bought in the first place.

Pros: Bosch is better
Cons: generic pump failed

Bosch Fuel pump

Something basic with an indirect injection diesel engine and Bosch VE fuel pump. Then it can be run on any old oil that’s remaining long after the petrol has turned bad. Including engine oil from abandoned vehicle sumps. Peugeot 405 estate would be ideal.

Pros: run on any old oil
Vehicle: Peugeot 405

Eu tenho uma Tr4 2014...peguei com 15 mil km em 2015...em 10 anos ela teve 3 problemas: 1 motor do ventilador do radiador, s\u00e3o 2 ventiladores. 1 bomba de gasolina, que eu troquei numa bosch gen\u00e9rica e os amortecedores, mas esse nem conta.

Pros: troquei bomba de gasolina
Vehicle: Mitsubishi Pajero
Mileage: 15000 km

Bosch Fuel pump

That rattle at around 2k rpm in the CP3 area is usually the coupler or pump itself starting to wear. The CP3 on the 6.7L is gear-driven and there’s no adjustment or ‘re-phasing’ you can do — it’s either good or it’s not. A little gear whine is normal, but a hard rattle means the internal plungers/bearings are coming apart. I would plan for a replacement rather than trying to nurse it along. Stick with a quality new or Bosch reman; the cheap Delphi/Rockauto pumps have a spotty track record and a failed pump will send metal into the fuel system. Also inspect the harmonic balancer and flex plate bolts, since they can mimic pump noise. If you’re not comfortable diagnosing, have a diesel shop listen before you throw parts at it.

Pros: quality new or reman
Cons: spotty track record, internal wear
Part number: EX836105

Bosch Fuel pump

Too many fuel pumps die because of people upgrading the pump with has more amperage but they don't upgrade the fuel pump wires to handle that extra heat. Your setup still seems pretty mild so maybe you don't need to replace your wires but can just run a Bosch 044 like everyone else (including me) has tested tried and true with 660cc Siemens injectors.

Pros: tested tried and true
Cons: extra heat
