TLAC made a superb job of their oil access pop up on G-TLAC and I wasn’t convinced mine would look as neat and, having gone through the pain of over trimming one top cowl, I opted for a slightly different approach.
This involved drilling a pilot hole to check that I was directly over the top of the dip stick and then widen this to take account of the larger diameter alloy petrol cap.
The dremel came into its own as the hole was neatened to accept the fitting.
Although I knew the flat nature of the alloy cap would require a small amount of filler to make up the slope of the cowl it all turned out very well. The filler will be smoothed down to ensure a streamlined finish then paint with the top.
Made up a supporting alloy ring for the underside – The fitting comes with a cork ring but no metal backing as I guess it assumes you are fitting it to a car.
I now simply pull the flap, half turn and out pops the access. Simple and easy to get.
