My local bosch approved shop says that they can upgrade the internals of my IP to and I quote "Flow way more fuel than you could ever use" He says he knows of larger plungers that will fit etc...I don't know the names for the parts in an IP so I cannot continue but I am going to stop by there this week sometime and he says he'll explain to me what he can do.

This is an mw pump from a 82 300D
