Adam, you should be aware that a SIGNIFICANT re-design of the 226 engine took place during the 1947 model year, and that wiring, fuel line,exhaust and other connections changed as a result (along with various engine parts). Since you did not specify which type you may need, I have posted two pictures. The first shows the original version of the 226 used in some earlier production Frazer and Frazer Manhattans; the exhaust pipe attached at the exhaust manifold at the front area of the block and the single-action fuel pump is mounted on the side of the block at rear. The second shows a car being worked on in the company garage; This is the later type of 1947 engine with exhaust pipe hooking up to the manifold in the center area of the block (directly below the carb area) and a fuel pump on the side of the block up front.
Also, is there a tank with provision for rubber hose line attachments inside the right fender area of the car? This will help identify if your fuel pump is single-stage or double stage. Manhattans used both. You can check this out in the KFOCI HANDBOOK Version 4.0 CD under the area on 1947 Frazer Manhattans for additional info.
Remember that KFOCI members get free ads in KFOCI MONTHLY BULLETIN and there is a Wanted section for needs like this. You should also be looking for the blue/black cover 1947-48-49 factory shop manual and the 1948 issue ILLUSTRATED factory parts list covering the 1947 and 1948 model year cars; this was the first illustrated factory parts book issued that covered 1947 model year cars.
