Posted: Mon Feb 25, 2008 2:11 pm Post subject: Fuel Tank Leak

After 190 hours a leak developed around the fuel line fitting with the strainer that goes into the right tank.  It appears the fuel is leaking around the flange inside the tank and coming out around the opening for the fitting.  They are QB wings so I can't take credit for not properly prosealing the flange to the fuel tank rib.  With no access to the inside of the tank I'm trying to come up with a fix short of removing the tank.  First two attempts to come up with a fix failed.  The third attempt appears to be working knock on wood.  I'm getting really good at taking the wing root fairing on and off.

  

 The thought of messing up my paint job removing the tank screws is not pleasant.

  

 TIP - Those in the process of building the tank don't spare the proseal around the flange that is riveted to the rib.

You did not say how you fixed it on the third try.  I have a leak on my QB tank and Van has sent me a new tank but the thought of replacing and repainting the tank has stopped me short.  My leak (the third discovered on this tank) is at the outboard panel.  Any suggestion short of opening an access hole?

I'm lucky in a way in that I can see the leak by removing the wing root fairing. I put two flat washers over the strainer and on to the fitting.  I put a liberal amount of proseal around the washers which I hoped would push the proseal into the opening around the hole in the fuel tank rib when I tighten the fitting.  The washers also might help in tightening up the flange in the tank against the rib.  If it starts leaking again I'm going to try thinning out some proseal with MEK and suck it into the hole using a suction pump on the fuel vent.

  

 After that I'm out of ideas and will have to remove the tank to cut an access hole so I can get to the flange.  A paint cutter (The Yard Store) works fairly well around the screws to keep the damage to the paint at a minimum.  A friend with a fuel tank leak used the cutter around the screws of his painted RV-7 and it looks OK - not great but OK.

they sent you a new tank?? wow, I thought they were  handing out 4 inch "access panels".

  

 Never understood the logic of repairing a pinhole  sized leak with a 4 inch access panel.

Consider that likely the replacement tank was built by Van's staff

rather than in the Philippines. Might just be a bit better

construction.

Yes they did.  However, my first leaks began on two rivets, then at the fuel pick up area, and then at the outboard baffle.  I had no difficulty asking for a new tank.

Scott told me that it will be built here with the knowledge that it is  

going to replace a tank for an unhappy customer.  I am also  very  

pleased that we deal with such a great company that backs up their  

product without question.  They certainly make up for that rare  

deficiencies that come up.

That makes sense,Always nice to hear how Van's  stands by their product when there is an obvious problem. 

 Thanks for explaining!
