hey guys,

i wonder how exactly the jet pump system can be involved in a twin fuel pump setup (or big single aftermarked fuel pump like walbro GST525).

i know some companies such as radium or deatschwerks provide a jet pump to hook up inline. But i thought it must be possible to build one too.

also as i know the jet pump on the factory or upgrade drop in pumps for quattros have the jet pump on the feeding side not in the return line.

does anyone build something like that and got some infos?
