----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----Hi Dennis; How much speed did you gain with all those hail modified surfaces? >grin<
If your fuel system has not been modified, you may have all stainless steel tanks or ternplate tanks. If so, your fuselage tank is held in place with two straps which must be kept snug and have felt or leather between the straps and the tanks to prevent chaffing. You should only have one fuel return line which runs from the top RH side of the fuselage tank down to the RH wing tank. Are your tanks welded or riveted together? (stainless are welded)
What I have noticed with the steel fuselage tanks is that there is very little air space at the top. The return line comes up pretty high (you can remove the fuselage tank cap and look down inside to see the return line) and it takes very little running of the engine to fill the tank. If you can get someone to help you, you could try pouring a little fuel in the tank opening to fill it up, while the other person looks at the tank from the rear to see where the fuel comes from. However, you will most likely have to remove the tank in order to effect a repair.
It is possible to remove the 5 gal header tanks without removing the control column. You have to remove the control wheels and shafts, disconnect the carburetor heat, brake cable and throttle, remove those controls from the panel and remove the fuselage tank after draining and disconnecting all the lines.
John Wright, JR., your local fuel tank repair expert, and I would recommend talking to him before you do much more than trouble shoot where the leak appears to be coming from. (217-698-8243)
Good Luck
