Hoot...
Please elaborate.... You say that performance problems and shutdown would occur before any damage from a second filter...
If that's true, then why don't performance problems and shutdown occur before an injection pump works itself to death trying to make up for a failed lift pump?
Well, come to think of it, maybe these performance problems do actually show themselves when a lift pump goes out, but some people just don't notice them.
But you really don't think the additional filter (which, if I'm not mistaken, goes inbetween the lift pump and the injection pump) adds any stress to the injection pump?
