I purchased a "J" bend from Summit and sectioned it to create a gentle ess bend, TIG welded the sections (2" OD pipe) and used some BUNA-N fuel-proof rubber and Seals-All to create the proper OD to fit inside the BMW filler pipe. Very little clearance between the 'glass body and the BMW sheet metal. I used a Sawsall to make a couple of vertical cuts in the sheet metal and bent the BMW flange inward about an inch. The supplied recess piece was widened (large Cobra style cap) and fiberglassed to the fender.
I used Rivnuts in the recessed part for the cap. Two 2" ID fuel hose pieces were cut and SS hose clamps are used for the connections. Very tight fit. The Seals-All is fuel-proof and will adhere to both the Buna-N rubber (1/32 thick) and the plastic BMW fill tube. One wrap on the fabricated 2" tubing was needed.
I'll try to get some photos up this afternoon.
