Fuel pump DELPHI or Bosch

Compra da bosch meu mano, melhor coisa que ce faz

I got two cinder blocks, lowered the pump onto the cinder blocks, then unplugged all fuel lines and evaporated lines. Then the tank was free. Fuel pump removal was easy. Just a hammered and a regular screw driver to loosen the lock disc. New Delphi pump was $450. Started right up.

It’s Delphi and I bought one recently. Build quality is excellent and it comes with the sock and new hardware.

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.

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.

it's a great aftermarket part(Rockauto). The wire harness so far for me hasn't given me major issues. I will say make sure the mechanic or you know how to install that correctly. The reason why I state this the last fuel pump job I had done my mechanic did make a mistake and wired it wrong causing a wire burn later on. Luckily he's not a asshole and fixed it for free since it was his fault. Traffic here is ass so the pump does get it's fair Share of work.

Mine went out at 270,00 on my 2002 Tahoe oem Delphi

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.

So I've changed out my original fuel pump (Pierburg) on my 90 Corrado back in Jan 2024. Replaced it with the Delphi complete unit with pump and sender. Now less than 2 years later I need a new pump.

I am on my third one since Jul. Had a freshly rebuilt q-jet (quadrajetpower) installed and the the first pump started to leak. Got a Delphi from Napa—there’s two different fuels pumps for emission vs no emission. First Delphi—non emission-installed and ran good for a bit. I did the grease the rod, push it in, installed pump. A few weeks later it stopped. I pulled it and the lever was bent. Second was another Delphi but the the one for the emissions. Drove it and one day it left me stranded and would pump fuel. Lucky I ordered a Carter off amazon. I swapped that one in and I get good fuel to carb.
