ok but I though the filling was through the intercooler pipe( one in and one out ) ?thats correct Renjean1. You could use the above method but requires more pieces.
1-M14 fitting JIC adaptor
1-½” JIC reducer adaptor
With the VAS fill adapter
Remove sump plug, screw in fill adapter, fit plastic hose to fill adapter, its a snug fit so hose clamp is optional.
If you have the parts to do it without the VAS filler tube, then by all means use it.
thanks for your answer !
