[TR] Quieting Facet Fuel Pumps

[John Macartney]

When 'uncle jack' blew his fuel pump last year in Vancouver (it was the only
failure we had of any sort) a BCTR member most kindly donated a new Facet pump
he carried as a spare in his TR4. The donor told me that in his experience the
operating pressure of that pump was about 8 psi and most Triumphs need around
2.5 to 3 psi max. To get round the clatter, he also donated a restrictor to
put 
in the fuel line. This looked homemade and was a piece of drilled bar.
The bar 
had a small hole drilled through it - about 1/16th and was
considerably smaller 
than the internal diameter of the fuel pipe. Held in
place with a hose clamp on 
either end. Not sure what additional load that
restrictor put on the pump itself 
but (a) it stopped the 'clacking' noise of
the new pump on first start and (b) 
got us to California and then back to
Denver CO with no further trouble. AFAIK, 
it's still there? Phil Ethier?

Subject: [TR] Quieting Facet Fuel Pumps

    I installed
a Facet fuel pump behind the drivers seat under the rear 
seat/parcel shelf. I
like the location. Good access and I can see the fuel 
filter by looking
through the spoke wheels. I can also change the filter of fuel 
pump without
jacking up the car. I mounted the pump on doubled 1/16th inch thick 
neoprene
washers to buffer the noise.
    So, now when I drive the car it sounds like a
woodpecker pecking away under 
the parcel shelf. Damn the thing is loud. What
is the best way to quiet it down? 
All my concocted ideas are unbelievably
complicated and probably overkill. Any 
listers have a simple way to quiet
this thing down? 

    TIA,

    Bill in Tehachapi
