Marcos Maniacs

Does anyone have one?  It is red in color has 5 pins and is nothing but resisters in series (one leg get power from the key as it tries to start that preliminary allows for the signal to the fuel pump relay which upon starting the circuit is completed by the flapper valve being held open by air flow, you can see I took it apart)

I measured across a couple of the resistor and they are shot.

Any help would be appreciated (I have found them available in UK at Rimmersbros) but if someone knows a source in the states (roverland parts was not very helpful)
