Fuel pump still noisy

[Bitsyncmaster]

My Tahoe fuel pump makes more noise (running normal) then I like. Looking around with it running it seems to resonate with the tub running on the passenger side. I think I need to make the feed pipe mounted with a rubber isolator. Has anyone else noted this noise. I would guess doing a Dyomat on the tub would also help but want a quick fix.

Edit: Just did a little more checking and I think the noise is the return line. I can feel that line vibrate at the engine and FV. Now is it caused by the PPR or FV? I would guess the PPR is more of a linear device so my guess is the FV causing noise.

Well I just answered my own question. Jumping the fuel pump on with the engine not running I don't get the resonating in the cabin. I do hear the pump running and a little of that noise seems to vibrate the fuel tank closing plate. Just feeling around with my fingers.

So my problem is the FV is pulsing that return line.
