RE: Welcome to Club SAITO !
Hello; I had a look at my Saito 45s and I think that the collar that the fuel nipple attaches to will rotate. Loosen off the nut that is closest to the niple and see if you can twist the nipple to where you want it. The reason I think that the collar will turn is; each of my 45's carb nipple is in a slightly different position. If you have the 45s then the nipple points straight up, and can't be moved, it has the same carb as the later 50's and 56's. You can always cut the fuel pressure line and put a piece of brass tubing in the joint where you can get at it easily.
