Danish,
If you have the time, I would check it. It is usually better to tune things up than just live with them.
I would try "surveying" it before you go to the trouble of popping it open. Take the tank off. Find a level bench. Fill your syringe with some test fuel. Lay tank along edge of bench and fill thru feed line until it just starts to come out the uniflow. (This assumes an "all tubes forward on centerline" tank.) Pick the tank up and avoid spilling any fuel. Lay it down on the opposite side (top becomes bottom) and see if fuel comes out. If not, continue filling until it just starts to come out. Pick the tank up and flip it over again. Now if it does, then the two lines are not at the same height, and you can guesstimate how far off they are. You get the idea, and can work out the variations.
Or you can just unsolder it if you like doing that kind of thing....

PS--You might also eyeball the tank from the side. Sometimes they are not quite level and that can screw you up. It is easy to do if the thrustline and the wing centerline are offset, and if the nose doesn't have any straight, horizontal edges.
