Something like a 1uF film, a 0.1uF film and a 0.01uF film would probably suppress the spikes some more. Cutting the leads of the pump back as close to the pump as you dare, and soldering the cap(s) on close to the body of the pump would likely have some benefit, but I don't think that anything beyond, a single 0.1uF at the normal lead length, is really going to have an impact on system performance. IMO the 0.1uF cap is enough.

Do you mean one of these?:
I'm just having a hard time choosing the right type, with these definitions:
