Walbro GSL392 very noisy
 

Is it normal for the Walbro high pressure/flow pumps to exhibit a loud whining noise? Mine sounds like I've got e-fans on high, easily heard over the exhaust noise. It's an external fuel pump mounted to the frame rail under the driver's door. I used the foam sleeve to insulate it but that doesn't seem to help the noise.

It beats the Airtex in-tank pump to hell and back in terms of pressure, though. I've never had the FPR bleeding pressure during the pre-start KOEO procedure, the rail gets right up to 60psi in a split second.

Still loud and working?

Yep, definitely not quieter with age, but still performs like new.

Whats the setup on your fuel system? Im thinking about ditching my a1000 and going with 2 of these. Im new to fi, so im not even sure what i need for a 408 on 16-18 lbs.
