One of the first things we did with our YJ was get rid of the computer-controlled Carter carburetor. To do this we first bolted on a Trans-Dapt adapter (PN TRD-2086) from Summit Racing. The mounting flange on the stock YJ intake is very small, so to avoid vacuum leaks we had to make a thicker gasket out of some spare gasket material we had. As an added precaution, we filled the bolt mounting holes with a little silicon gasket maker. We then made a new upper gasket to ensure a leak-free seal around the adapter bolt holes.
