timb2117 Posted October 29, 2020 Share Posted October 29, 2020 Hi guys checked the build manual nothing...New aero fuel cap and neck assembly, does the cork gasket go outside the painted bodywork underneath the aero cap part. OR;Inside the bodywork on the flange of the neck assembly where it contacts the inside of the body panel?Ill probably double it up with fuel proof gasket anyway but want to get it correct. Thanks heaps in advance for this simpleton Q? Link to comment Share on other sites More sharing options...
SM25T Posted October 29, 2020 Share Posted October 29, 2020 Outside. Edit ... when I retrofitted an aero filler to my car, it was just one piece that fitted from the outside, with the cork gasket between it and the paintwork. Link to comment Share on other sites More sharing options...
Wrightpayne Posted October 29, 2020 Share Posted October 29, 2020 If you study the components, the fixed part of the aero cap assembly has an o ring which seals against the inside of the filler neck. There is no need to seal the neck against the inside of the ally. RegardsIan Link to comment Share on other sites More sharing options...
timb2117 Posted October 29, 2020 Author Share Posted October 29, 2020 Brilliant I knew you guys would know - yep I was looking at the o ring thinking done deal! Many thanks all great, now hope my fuel system overhaul fixes the pesky lumpiness at 5500 rpm, soon to find out!Thanks again. Link to comment Share on other sites More sharing options...
