Walbro FP actin up...
These pumps seem to simply be inherently noisy by design once they "wear in". The solution lies in potentially sourcing the Zylex FP(Zytec ITP116 high pressure fuel pump) that the FQ400 uses stock, spoke briefly months ago with Adam of Z1 about it, the price might be somewhere within this stratosphere if we could get enough people on a groupbuy, PM me if you're interested in potentially investigating this remedy for the "telltale pump".

contacted walbro. they replied with half-a-dozen questions so I replied with the answers...waiting for their next reply.
p.s. It did it again today...but only for 10 minutes or so on a 5 hour roundtrip.

Walbro told me to contact the vendor that I purchased the pump from.
The vendor told me to return it for a replacement.
Like I have the time to pull the pump out, send it back, wait for replacement, and reinstall it.
If I have to pull it out, I'll replace it with something else.

i really think your getting tooo bent out of shape over a fuel pump that whines.




Mine does get louder as the tank gets more and more empty...
