At the start of this week I'd talked to Chris about how to best attach an Aston fuel cap to the BMW pipe. Chris kindly talked to Car Builder Solutions on my behalf and worked out what I needed. Quick call to CBS and wallet was lightened by over £200 to get the cap, piping and connections.
Not the most straightforward method of placing a fuel filler (or cost effective!) but 4 hours of labour this evening has connected the pipe to the BMW pipe and created the recess for the Aston cap to sit in. Still needs another go of filler and sanding to finish it off but nearly there.
And how the cap will roughly sit in it.
