Has anybody else had problems with the quick build tanks leaking. Mine seem to be leaking around the outlet port. The sealant they used is turning gummy and it is more of a seep than a leak.I cant believe they used rivets on that particular piece as there is no way to snug them a little.Any ideas on how to remedy this?

Bruce, i did. After making major repairs without success, gave up and got a new tank. Van supplied the tank for free since it was QB tank. 

Major reapir: removing the tank, cutting a hole on the back side of the tank and reaching inside. Vans supplied the repair kit. 

If you need more detail, email me offline.

Repairs from the outside do not work.

Bruce  

I had a leak on the right quick build tank and was finally able to determine it was seepage around the round head rivets on the flange which hold the outlet fitting. I used scotchbrite and alumiprep to clean and roughen the area. I then rinsed well and dried. I covered the area in proseal. It has held leak free so far. I was able to do this with the tank and wing installed.

I have 3 rivets that were seeping fuel on the QB tanks.  Unfortunately it wasn’t apparent until I had the airplane painted (aaggghhh!)  Previous posts here mentioned using the green Loctite which penetrates threads that are already assembled.  It took a lot of applications but appears to be working.  Not as good a fix as the major repair kit or sending the tanks back to Vans, but cheap and a lot less work if you want to give it a try.

The late Mark Ritter had the same problem. He tried coating the outside with proseal and several other fixes. He finally was successful by pulling a small vacuum on the tank and sucking proseal into the leak. I don’t remember if it was deluted. I have a very small leak around the drain flange and have not been successful with the vacuum method.

Thanks for the suggestions guys, I will give them a try. My concern is the gummyness of the proseal around the leaks, its like really tacky, like it was not mixed properly. I will attemp to remove and clean today and see where that gets me. It sucks that it is both tanks at exactly the same spot.

I've had leaking rivets in both wing walk areas, 4 in each side.  It's

leaving a nasty brown stain that's been steadily growing on the one I

haven't repaired yet.  Gets on your clothes if you sit on the wing,

too.



I tried loctite without any luck.  I finally drilled out the leaking

rivets and installed some closed-end blind rivets.  I put a lot of

proseal into the hole and all over the rivet before I popped it in.

The new rivets aren't quite as flush as a standard rivet but I can

live with that.  It's been several months and so far the leaks are

fixed.  Still needs to be repainted though.

David,



Did you use 3/32" or 1/8" closed-end rivets? I have been unable to locate any less than 1/8". If you have a source for 3/32 I would appreciate the information.



Thanks

How did you drill out the rivets without anything falling into the tanks? I 

would think a vacuum would pick up the small pieces but usually I punch out 

the drilled rivet and need access from the inside.

Thanks!

Try access by removing the fuel float sensor.

Grease on the drill bit helps alot to capture chips.  Other than that,

you just have to be pretty vigilant about getting all the pieces out.

We have a boroscope that fits into the screen outlet.  A small piece

of sticky tape on the end of the scope grabs the rivet.  Tap on the

bottom of the tank and they sort of migrate towards the screen by

gravity.  By finding one tail at a time you can keep track.  I only

changed a few, a whole bunch would be too tedious this way.

One of my QB tanks leaked in exactly the same place (seemed to be leaking between the riveted fitting and the rib).  There's no visible proseal in that area, though the proseal on the areas of the tank I can see looks fine (not gummy as you describe).  I put the finger strainer in and put new seal around it.  Now no air leak in testing, but I haven't filled with fuel yet.

OK I cleaned all the gummy sealant out of the way and did an air test and found it was leaking between the rivets. I thought maybe it was the fitting but after changing them out my conclusion is between the rivets. I put the fittings back in place and put a vacuum on the tank and tried some green loc tite. I am letting it dry over night and then will air test again tomorrow. I might even try some epoxy around the edges of the fitting before air tests. By the way the tanks can take quite a bit of pressure, my plan was around 3 lbs but the valve got kicked and it went up to 20lbs, really made the leaks standout though. The tank came out with no visible problems. After I get the left one  one stopped on to the right. Seems there was a problem on the day my tanks were assembled in the  Philippines.

Hard to believe 20 lbs didn't distort/deform/ destroy the tank... You must be one lucky guy.
