Subject: [alfa] re: What is this FISPA device?
I've heard that these devices are vibration dampers for pulses
in the fuel. I don't really understand it, but I heard it from a
mechanic. I have no verification of this, in fact, I don't know if
I believe it.

For what it's worth, I know that more modern (electronic) sequential
FI systems usually have such devices. I can understand that you
don't want the momentum of fuel in the rail to screw up your fuel
delivery, and similar issues may apply inside the Spica pump. What I
don't understand is why batched injection systems like L-Jet don't
have these, because I'd think that pulses in the fuel would be a
bigger deal with all the injectors opening and closing at once.
