RE: [DML] Fuel pump Buzz/Hum and engine cutting out briefly

Yes and no.  The problem is most likely caused by heat coming off the
radiator fans.  Purchasing your favorite vendor's heatshield, which mounts
to the front frame extension behind the fans, should fix this problem.


The noise you are hearing is indeed the fuel pump, but it usually isn't
going bad itself.  What's happening is the rubber pick-up hose underneath it
is collapsing because of the high temperature of the gasoline.  This strains
the pump, because it has to work harder, so theoretically it can prematurely
wear out your pump, but usually this doesn't happen for awhile.


I've had Dave Bauerle's heatshield on my car for about 8 years now, and I've
never had a fuel pump issue since.  Houston and Grady also sell a new
pick-up hose that isn't as prone to collapsing, from what I understand.


Hope that helps,

Subject: [DML] Fuel pump Buzz/Hum and engine cutting out briefly


So, driving back from DCS on Sunday, my car lost power on the highway 2-3
quick times, then the engine kicked back in (almost like inertia switch cut
in/out 2-3 times real quick)

I traveled another 45 minutes, and it happened one more time about 10 miles
from home. I made it home, and noticed that my fuel pump was
"Whining/buzzing/humming" quite a bit. I have never heard this before.

Is this the overheating problem? Do I need a new fuel pump? What kind of
lifespan should I expect?
Or am I barking up the wrong tree?
