My boost gauge has buzzed for a long time now when it gets loaded with 10psi and above. Not sure what gives? A buddy of mine said his did that so he moved the location of where he tapped in to get his reading. I'm tapped in to the manifold. I removed one of the pipe fittings and jumped 1 or 2 down to 1/8" pipe w/ Ferrell. He tapped in to the hi-ram intake or whatever you want to call it. I have buzzing he doesn't??? I checked and don't think I have any leaks and I'm not running low pressure....
Also, I've been having this buzzing noise coming from what I thought was behind the dash (like behind the radio), but the more I listen and try to pinpoint it, I think it's the fuel pressure gauge mounted down below the dash about level with the 4 wheel drive shifter. It's not run with an isolator, it's just a gauge and line from the pump to gauge. Do I need to bleed the line or something? Both my manual pressure gauges are making noises and one's a Stewart Warner and the other is an Isspro. Not sure what gives??

Thanks,

get a pressure snubber...page 567 on http://www.mcmaster.com/

 

My boost gauge was buzzing until I installed a snubber. Sometimes I can still make it hmmmm a little but not often.

 

Get the smallest orifice ones they have or what? They make 3 different orifice sizes in the 1/8" fittings. The fuel pressure gauge would be easy to get to. As for the boost gauge, does the snubber need to be directly on the gauge? Or could it be installed on the engine side of the boost line? Thanks guys... I think I'll give it a try!
