I just got thinking. older Volkswagons with fuel injection ( port and TBI ) have external high preassure fuel pumps, the tank pump is only a transfer pump. some of these engines are turbocharged. couple towns over, is the VW Parts USA ( 1800-VW- Parts ) junkyard, that ships worldwide, and is well known by the VW tuner crowd. they sell new OEM parts ( real cheap too ), as well as used parts. I could get a brand new fuel pump that can pump 20 PSI, and maintain a good flow. those guys are pretty knowlagble about the VW stuff, I'v dealt with them b4 ( brother had a couple VW's that always had somthing wrong ), so they could probably get me flow # and a good deal on somthing that would work. it's all Bosch stuff, so that's not bad.
