ok, so this is the ProTurbo tank adapter im now selling
it has 4 X 3/8NTP outs, that ill allow from -6 to -10

so you can run two -10 out to your efi fuel pumps, a -8 return and a -6 to drain the fuel from your tank

perfect
or
if you only want one out, just plug the ones your not using with NTP plugs
you can use the standard intank filter and washers

This it the highest flowing adapter out there, all the passages are as big as you can get from a stock vw tank




there £40 each
