My fuel pump makes a pretty load ticking noise which drives me crazy.
I replaced it with an ACDelco EP1000 which is supposed to stop the noise.

However mine still makes the noise.

BigKofJustice has a video on YouTube for this as well.

Anyone else have this issue.

 

I posted the video and I was incorrect that it was a more silent model.

It's normal operation for it to tick while running and during the start up/glow plug sequence.

Later model year H1's relocated the fuel pump to the left frame rail I think.

I believe there is an AMG part number for a rubber isolator that wraps around the unit that reduces the vibration to the a-pillar.

I just got used to it, the 6.5 diesel trucks are pretty noisy.

 

Hello folks, have a H2 and the fuel pump I believe is got a major whine to it when low in fuel. Can anyone tell me if this thing is immersed in the gasoline tank? Usually when I fill up, I can barely hear it if at all. Or is this whining a symptom that its going to fail? Is the fuel pump exterior or in the fuel tank on the H2? Thanks in advance.
