So whats with the TRW ones? Who / what are they, I see reference to them as an aftermarket suppler, so they have there own version of the pump they sell as a standalone also?
Looks like all these pump configurations have a simaler shape / guts I bet, but the fittings and mounting are all a little different.
Yes, that could work too, most of the outboard systems just power the pump when they want to move, this thing takes a few seconds after key on to start so that could be a little annoying.
