Anyone got any ideas on how to supress electrical noise from an in-tank fuel pump? I have a high-frequency "Sizzle" from the pump when running - what value cap can I use across the terminals?

If it helps, it's a '94 Renault Laguna.

You must treat it like any other noise in the system. In my old VW, fuel pump noise was corrected by putting a heavy-duty noise filter on the continuous power wires to the player and amplifier.

Have you been through the noise entries in the FAQ?

Yeah, but this is with a filter already in place. I think in this case I need to suppress at source.
