The pressure output hose from the pump goes out one of those holes, 
through the damper, back through the other hole, and to the left fuel 

I now suggest:
Forget the damper and the two holes. Route the hose directly to the 
left fuel line.

The two holes above "hold" it.

1) intake from gas tank connection with hex nut via fuel filter
2) pressure output (via damper) to the left fuel line
3) overpressure bleedoff line routes back to the tank in case a 
pressure line gets pinched somewhere.

If it's mild, ignore it. Otherwise you try calling radiator shops. 
Many of them do this service.
