Fuel Pump noise

[lawman349]

Fuel pump just got really loud lately (for the last 100 miles or so.)

I just got the truck back together from doing headgaskets, studs, and the EGR cooler upgrade. The fuel filters where changed when the motor was fixed. (less than 1000 miles ago.)

I am used to hearing the fuel pump when I cycle the key to th 'ON' position, but it has been MUCH louder lately. I can even hear it going down the road. It sounds like a power steering whine ...

SO - it the pupm fixin to take a crap? I dont seem to have any other issues. Truck runs great. I just dont want to have to replace injectors or get stuck on the side of the road because of a fuel pump.

What do yall think?

I think that is a big problem, fix it before you damage injectors. If you dont have the blue spring update, I would do that too. It won't take long at all to damage injectors from low fuel pressure.

Thats what I was thinking... I am gonna bite the bullet and do it.

The blue spring update was done when I rebuilt the motor. I wonder if that pushed the fuel pump south...

Could have finished the pump off, I suppose. It's best to check fuel pressure after install to ensure it was done properly.

fuel pressure was good. IIRC it was like 60 at idle. DOnt remember the exact number.

Fixed it. No more noise.

...except from my wife. That fuel pump was EXPENSIVE!!

(cheaper than injectors, though.)
